Epic Games Launcher Preview Beats Steam on Speed, but AI Raises the Stakes

Epic Games released its Epic Games Launcher preview with a striking claim: the rebuilt client starts 46% faster than Steam. The company also says artificial intelligence helped write and review the new software.

That combination turns an overdue application redesign into a public test of AI-assisted development. Epic is not merely promising a quicker launcher. It is tying a consumer product, a direct Steam comparison, and its wider AI strategy together.

The speed claim needs careful framing. The test was commissioned by Epic, the preview remains unfinished, and several legacy features have not arrived. Steam also competes through its mature platform, not startup time alone.

Still, Epic has placed a measurable result in front of players. If the software survives broad testing, the release gives AI coding advocates a credible production example. If bugs, missing features, or security concerns dominate feedback, its provocative launch message will age quickly.

The Epic Games Launcher Preview Rebuilds More Than the Interface

Epic has replaced the launcher's technical foundation instead of applying another visual update.

The company released the preview on October 14, 2026, for Windows, macOS, and Linux. Linux receives a native Epic launcher for the first time, although many games still require compatibility tools or lack Linux support.

Epic describes the release as a new foundation rather than a facelift. The company says it rebuilt the application from scratch using a different technology stack. Existing functionality guided the design, but the development team did not reuse the old client’s code.

Martin Keely, general manager of the Epic Games Store, told PC Gamer that AI helped write and review new features. His explanation matters because “vibe coded” can mean anything from occasional autocomplete to extensive code generation.

In this case, Epic presents AI as part of the implementation process. Vibe coding means describing desired behavior to AI systems that generate code, which developers then inspect, test, and refine.

The resulting application unifies the Store, Library, and Develop areas inside one common frame. Recent games remain accessible across views, while the social panel supports parties and voice chat.

The library receives a larger overhaul. Users can switch between grid and details views, create visual collections, hide games, and filter titles by attributes such as platform or genre.

Each game now has a dedicated page containing status information, play controls, add-ons, activity, and update details. Epic also added a centralized download manager with live network, disk-read, and disk-write speeds.

These features matter because several already exist in competing clients. Epic is not establishing a new category of launcher design. It is addressing shortcomings that made its existing software feel incomplete and slow beside Steam.

Former Epic Games Store leader Steve Allison acknowledged that problem earlier in 2026. As documented in a launcher interview, he said the old client repeatedly contacted backend services when users moved between sections.

That architecture could make each click depend on network conditions. Rebuilding the shell allows Epic to reduce those repeated waits instead of hiding them behind a refreshed interface.

The preview also carries accounts, purchases, installed games, cloud saves, and progress into the new client. However, installing it automatically removes the legacy launcher from that computer.

Users can return to the old version later, but the replacement process adds friction to casual experimentation. That choice reinforces the preview’s real purpose: Epic needs sustained use and actionable feedback, not brief curiosity.

The release therefore changes two things at once. Players can finally test Epic’s promised performance overhaul, while Epic can test whether AI-assisted code holds up outside an internal demonstration.

Why Speed Is Now Epic’s Opening Against Steam

Epic is targeting Steam’s daily user experience because store exclusives and free games have not erased the platform gap.

A launcher sits between a player and every game tied to that storefront. Delays during startup, browsing, updates, or downloads accumulate across hundreds of sessions.

Epic has chosen startup time as its headline metric because it is easy to understand. The preview website lists 5.47 seconds from a cold start to the store for its new client. It lists 10.07 seconds for Steam.

That difference produces Epic’s claim of a 46% faster cold start. The same page calls the new result 1.8 times faster than Steam, another expression of the measured ratio.

Epic also reports a smaller advantage when restoring each application from the background to its library. Its launcher took 0.36 seconds, while Steam took 0.42 seconds.

The percentage difference is 14%, but the practical gap is only 0.06 seconds. Most users will notice the cold-start difference more readily than the background result.

Epic says Keywords Studios conducted the October 2026 testing as an independent third party commissioned by Epic. The published methodology covered five tests on each of 13 machines.

However, Epic excluded the three lowest-end machines from its reported average. The company warns that individual results will vary, but it does not publish every machine configuration or individual measurement.

Those limits do not make the result meaningless. They do mean the 46% figure should be treated as a commissioned benchmark, not a universal outcome.

PC Gamer received an advance demonstration and reported that the improvement appeared significant. The publication also noted that it had not independently tested the client when its article appeared.

The comparison gives Epic a sharp promotional line, but Steam is a difficult opponent to reduce to one timer. Valve’s client includes years of accumulated features, including community systems, controller tools, Workshop support, family functions, streaming, and extensive library management.

More functions can create more startup work. A lighter preview could therefore outperform an established client while offering fewer capabilities.

Epic acknowledges that its first release is “light on features.” Its playful “speedboat” description captures the strategy: establish speed first, then add weight without restoring the old delays.

That sequence creates the central pressure on Steam. Valve does not need to panic over several seconds, but Epic has identified a dimension where its unfinished product can claim a numerical lead.

The pressure also runs back toward Epic. Once the company makes Steam the benchmark, players will compare far more than launch times.

They will compare account tools, social behavior, storefront navigation, download reliability, game discovery, refunds, controller support, and overall trust. Epic has invited that broader examination even though its headline covers only one narrow task.

The Epic Games Launcher preview therefore changes the competitive conversation without settling it. Epic can credibly say the new client starts faster under its test conditions. It cannot yet say that players will find the total platform better.

Vibe Coding Is Both the Mechanism and the Message

Epic wants the launcher to prove that AI-generated code can support a widely distributed consumer application.

The official launch announcement begins with a joke: “Programming is hard.” Epic then says it vibe coded the new client to make it faster and more responsive.

The phrasing is deliberately provocative. A company that builds Unreal Engine and operates Fortnite obviously still employs professional programmers. The joke signals that Epic wants its AI use discussed, not buried in development notes.

Keely’s comments provide the more useful explanation. Epic started with a new architecture, selected a different technology stack, and used AI to write and review new functionality.

That account describes AI-assisted software engineering rather than unattended generation. Human developers still decide the architecture, define requirements, evaluate output, integrate components, and approve releases.

Those steps are crucial because code generation is only one part of building dependable software. Authentication, payments, updates, local files, cloud saves, and game launching create failure paths that a generated interface demo might never encounter.

Epic’s approach also reflects a wider company strategy. CEO Tim Sweeney has described a major internal move toward AI acceleration, with teams retooling their development processes.

Sweeney argues that the objective is higher output rather than simply reducing staff. According to a development interview, he wants teams to build more and improve the resulting work.

The launcher gives that strategy a visible test surface. Unlike an internal prototype, it interacts with millions of accounts, diverse hardware, large game libraries, and unstable network conditions.

It also handles commercially sensitive workflows. Users browse products, manage downloads, authenticate accounts, and make purchases through the application.

That makes the preview more consequential than a small AI-generated utility. A bug can interrupt access to games, confuse installation state, expose account friction, or undermine confidence in Epic’s engineering process.

At the same time, the rebuild shows where AI assistance can have practical value. Replacing an aging client often requires recreating familiar behavior while changing the underlying implementation.

AI tools can help generate routine components, translate patterns into a new stack, produce tests, and review repetitive changes. Developers can then spend more time on architecture, profiling, edge cases, and integration.

The public evidence does not reveal which AI tools Epic used, how much code they produced, or what proportion survived review. Epic also has not described its security testing, code-ownership rules, or defect rates.

Without those details, “vibe coded” remains a branding phrase rather than a complete engineering methodology. It tells readers that AI played a meaningful role but not how Epic controlled the resulting risks.

That ambiguity serves the launch campaign because it attracts attention. It also creates expectations that ordinary software projects avoid.

Every visible defect can now become evidence against AI-generated code, even when comparable bugs appear in traditionally written previews. Conversely, a smooth release will be presented as support for a development process that outsiders still cannot inspect.

Epic chose that scrutiny. The company connected its new architecture, speed claims, and AI strategy in the same announcement. The launcher must now support all three parts of that story.

What the 46% Faster Claim Does Not Prove

A faster benchmark does not establish reliability, security, or performance across every computer and network.

Epic’s comparison measures a defined journey from cold start to the storefront. That is useful, but it does not cover signing in, validating installed games, processing updates, or recovering from interrupted downloads.

It also does not measure a long session. Memory consumption, background processor use, network activity, cache growth, and stability can matter more after the opening screen appears.

The test population deserves attention. Epic reports results from 13 Windows machines but excludes the three lowest-end systems from the average.

Users with slower processors, older storage, limited memory, or poor connections might experience a different ranking. The available disclosure does not show whether both clients had comparable libraries, caches, settings, or login states.

Steam’s 10.07-second figure also needs context. Valve updates its client regularly, and its behavior varies with account configuration, installed features, and background tasks.

A benchmark captures a version and setup at one point in time. It does not guarantee a lasting lead after either company ships another update.

Epic’s claim that the library loads 30 times faster is even less defined publicly. The landing page provides the multiplier but does not state the underlying times beside it.

That missing denominator makes the number difficult to evaluate. A 30-fold gain can be impressive, but the practical difference depends on whether the old wait lasted milliseconds or several seconds.

The phrase “faster startup” also appears in several forms. Epic lists 5.47 seconds for the complete cold-start journey, while another claim says the Store opens three times faster.

Those measurements may refer to different stages. Readers should not combine them or assume every screen receives the same improvement.

Tom’s Hardware correctly emphasizes the limits of the evidence in its benchmark analysis. The publication notes that Epic commissioned the testing and offered little direct performance data against its own legacy client.

That omission is notable because the old launcher is the product Epic must replace. Steam supplies a useful competitive headline, but existing Epic users need to know what improves in their daily routine.

Security raises another set of questions. AI-generated code can reproduce unsafe patterns, misunderstand requirements, or pass superficial tests while failing unusual conditions.

Traditional code can do the same. The difference lies in how teams review generated changes and whether developers understand the systems they approve.

Epic has not published an independent security assessment for the preview. There is no verified evidence that the application is unsafe, but there is also insufficient public detail to infer stronger assurance from the speed test.

The preview label is therefore important. Epic explicitly warns that some functions might not behave as expected and asks users to submit bug reports.

Early testers should evaluate more than the time required to reach the store. They should watch installation state, downloads, cloud saves, sign-in behavior, account controls, and background resource use.

Competitive players received confusing guidance during the launch. An early version of Epic’s material reportedly recommended that some developers and competitive players remain on the legacy client.

Epic later removed that recommendation. Senior communications manager Brian Sharon clarified that games, developer tools, and non-gaming applications should operate normally after launch.

The correction reduces concern about game services, but it also illustrates why preview messaging needs precision. A fast client gains little trust if users remain unsure which workflows Epic considers ready.

Missing Features Turn the Steam Comparison Into a Tradeoff

Epic’s speed advantage matters only if the launcher retains it while approaching the functionality players expect.

The preview already contains the core path from account sign-in to game launch. It carries purchases, installed titles, saves, and progress from the existing client.

However, Epic says certain social functions and account-management options remain unavailable. The company is working toward feature parity, meaning the new launcher must eventually reproduce the important capabilities of its predecessor.

Feature parity is only the first threshold. Steam supplies the external comparison, and Valve’s client has become more than a storefront or executable list.

Players use Steam for community pages, discussions, reviews, mod distribution, controller configuration, remote play, family management, broadcasting, screenshots, and marketplace functions. Not every customer needs every tool, but their combined value strengthens the platform.

Epic’s redesigned library closes some visible gaps. Collections, filters, dedicated game pages, and centralized downloads make a large catalog easier to manage.

Users can also connect PC libraries and view shortcuts associated with games from other clients. That feature recognizes a basic reality of PC gaming: many players maintain accounts across several stores.

Yet a unified view is not the same as a unified platform. Purchases, updates, achievements, social identities, refunds, and community content still depend on the original services.

Steam therefore remains the primary opponent because its advantage rests on accumulated behavior. Players do not select a launcher solely during installation. They build libraries, friend networks, habits, and expectations over years.

Epic can reduce waiting without immediately changing those habits. The company must show that faster navigation makes its store meaningfully easier to use, especially after more features increase the client’s complexity.

The Linux release adds a more distinctive opportunity. Epic now distributes a native launcher for supported versions of Ubuntu, Fedora, and Debian.

The company is also rebuilding Easy Anti-Cheat support so Fortnite can eventually run on Linux. Easy Anti-Cheat checks multiplayer environments for unauthorized software and modified behavior.

Fortnite is not available on Linux through the launcher yet. Epic says it will proceed after reaching sufficient support among Linux distribution maintainers.

That project connects launcher adoption with a real catalog issue. Native store software is helpful, but Linux players need compatible games and dependable anti-cheat support.

The preview’s current system requirements also narrow its reach. On macOS, Epic supports Apple Silicon but not Intel-based Macs.

Windows support covers 64-bit Windows 10 and Windows 11. Epic lists four gigabytes of memory across Windows, macOS, and Linux, although storage requirements vary by platform.

These limits are reasonable for new software, but they remind users that the rebuild involves migration decisions. Faster software does not automatically mean broader compatibility.

The most revealing phrase in Epic’s announcement may be “new foundation.” A foundation succeeds by supporting what gets built later, not through its empty-state performance.

Each added social feature, account control, storefront component, and developer tool will test the architecture. Epic must preserve responsiveness while restoring functionality.

That is where the AI development claim becomes relevant again. Generated code can help teams move quickly, but rapid expansion increases the need for consistent design, testing, and ownership.

If Epic reaches parity without returning to the old client’s delays, the rebuild will look well judged. If performance declines as features arrive, today’s Steam comparison will describe a temporary advantage.

Three Signals Will Decide Whether Epic’s Experiment Worked

The stable release, independent performance results, and feature-parity updates will determine whether this preview represents durable engineering progress.

The first signal is independent testing across ordinary hardware. Reviewers should reproduce the cold-start measurement, examine the excluded low-end class, and compare resource use during longer sessions.

Those tests should also distinguish local interface speed from network-dependent storefront loading. If the Epic Games Launcher preview retains a clear lead across varied setups, the benchmark claim gains credibility.

If results vary widely or depend on carefully prepared conditions, the 46% headline becomes less useful. Epic would still have a faster client than before, but its Steam comparison would carry less weight.

The second signal is the path to feature parity. Epic has not announced a firm stable-release date, and its public roadmap describes a feedback-led progression.

Watch how quickly account functions and missing social features arrive. More importantly, watch whether each update preserves startup speed, navigation response, download reliability, and background efficiency.

A stable release with incomplete workflows would weaken the argument that Epic rebuilt the whole launcher successfully. A complete client that becomes slow again would undermine the architecture’s central promise.

The third signal is Epic’s treatment of defects and security. Preview software will produce bug reports, so the mere existence of problems will not settle the AI debate.

Response quality matters more. Epic needs clear release notes, rapid fixes, reproducible testing, and transparent communication when behavior affects accounts, purchases, saves, or installations.

The company should also explain more about its AI review process. Players do not need every internal prompt, but they deserve confidence that engineers understand and maintain the code entering production.

Linux offers an additional verification point inside these signals. Native launcher support becomes more meaningful when Fortnite arrives and Easy Anti-Cheat works reliably across supported distributions.

Failure there would not prove the launcher itself is flawed. It would show how difficult it remains to connect a fast new shell with Epic’s broader services and game ecosystem.

The company’s messaging will face a test as well. “Programming is hard” works as a launch joke because it contrasts with measurable speed.

It will work poorly during a serious outage or account incident. Epic has made AI part of the product identity, so its communication must match the confidence of that choice.

For players, the sensible approach is practical rather than ideological. Testers should record startup behavior, inspect downloads and saves, report defects, and compare the preview with their existing workflows.

Users who depend on missing account or social functions can wait. Preview participation is most valuable when people accept unfinished software and provide specific evidence about failures.

Developers and technology leaders should watch the release for a different reason. It exposes the gap between generating code quickly and operating software responsibly at scale.

The important question is not whether AI wrote a component. It is whether Epic’s team can own, test, secure, and extend that component after deployment.

The Epic Games Launcher preview has already succeeded at changing the conversation. It transformed a routine client rebuild into a direct test of Steam’s speed and Epic’s AI-first development strategy.

Now the company must preserve that advantage while adding everything the preview lacks. Try the client if unfinished software fits your risk tolerance, but judge the experiment by months of updates, not one benchmark.
