Epic Games released a public preview of its rebuilt Epic Games Launcher on October 14, 2026, introducing a completely rewritten software architecture created with artificial intelligence tools. Available now for Windows, macOS, and—for the first time—Linux, the updated desktop client aims to resolve years of user complaints regarding sluggish performance and heavy resource usage. Epic asserts that its new application boots from a cold start 46 percent faster than rival platform Steam, while acknowledging that the early build remains light on features and contains bugs.

Inside Epic’s AI-Assisted Rebuild

In its official announcement, Epic took a tongue-in-cheek tone toward the engineering overhaul, stating that “programming is hard” and explaining that the team “vibe coded” the replacement client to be faster and more responsive. Behind the casual phrasing lies a major architectural shift. According to IGN, Epic Games Store Vice President and General Manager Martin Keely confirmed that engineers rebuilt the client from the ground up on an entirely new tech stack. The rewrite covers the application shell, download manager, game library, and core storefront pages.

Rather than copying legacy code from the nearly eight-year-old launcher, a small team used AI agents to write, review, and test new code that replicated existing functionality. Keely noted in a briefing reported by The Verge that while AI agents wrote and reviewed the codebase, human engineers supervised and managed the entire process. Epic executive Steve Allison also pointed out that AI tools assisted with code efficiency, architecture design, and quality assurance, allowing the team to deploy across multiple operating systems simultaneously.

The release coincides with a broader corporate mandate regarding automated software development. On October 12, Epic CEO Tim Sweeney posted on X that the company had a “huge pivot underway,” reassigning developers to maximize AI acceleration. According to Business Insider, Sweeney emphasized that the reorganization is intended to help teams build more software rather than reduce headcount, following a separate round of layoffs affecting more than 1,000 employees in March 2026. The company’s internal push varies by department; while the launcher team relied on human-supervised AI output, Bloomberg reported that an Epic director working on an unannounced Disney project instructed staff to stop writing code by hand altogether.

Unpacking the Steam Performance Claims

Speed is the central selling point of the preview build. Epic states that the redesigned library loads 30 times faster than its predecessor, overall startup is twice as fast, and the installation footprint sits at roughly 300 MB. In direct comparisons against Valve’s market-leading storefront, Epic claims its preview client reaches the store page from a cold start in 5.47 seconds compared to Steam’s 10.07 seconds—a 46 percent reduction. When restoring the window to the library view from the system tray, Epic reports a time of 0.36 seconds against Steam’s 0.42 seconds, which it markets as a 14 percent advantage.

However, independent observers and testing details add necessary context to those promotional figures. According to Ars Technica, hands-on testing confirmed that the preview launcher loads its store page from a cold start a few seconds faster than Steam, provided no login prompts or updates interrupt the sequence. Yet the 0.06-second advantage when opening the app from the system tray proved imperceptible in real-world use.

The methodology behind Epic’s headline numbers also carries notable caveats. According to Game Rant, the comparison data stems from testing commissioned by Epic and conducted by Keywords Studios across 13 computer systems, with the three lowest-end PC configurations excluded from the final published results. Because the full hardware specifications and testing conditions have not been independently reproduced, it remains unclear how the software performs on budget gaming rigs.

Missing Features and Linux Expansion

Epic compares the current state of the preview client to “a speedboat and not a yacht,” warning users that the software is still in beta. While it introduces long-requested quality-of-life upgrades—such as customizable top-bar navigation tabs, a unified downloads page, a recent games list, and Steam-style library collections—several legacy functions are absent. Certain account management settings and social controls have not yet migrated over. According to Tom’s Hardware, the revamped social panel currently follows users between the store and library screens without an option to close or resize it.

Early messaging around the launch also caused brief confusion regarding stability. Epic initially advised Unreal Engine developers and competitive Fortnite and Rocket League players to stick with the legacy launcher. The company later removed that warning from its blog post; Epic Senior Communications Manager Brian Sharon clarified that once a game or developer application is running, all services function normally for both casual and competitive play.

For the broader PC gaming market, the most practical expansion is native Linux support, which carries major implications for handheld devices like the Steam Deck. Epic confirmed that bringing the launcher to Linux is the first step toward making Fortnite natively playable on the operating system. Before that happens, Epic must finish rebuilding its Easy Anti-Cheat software for Linux and ensure compatibility across a critical mass of distribution maintainers.

Frequently Asked Questions

Do the startup speed improvements apply to older or lower-end PCs?

It is not yet verified. Epic’s 46 percent faster startup claim is based on commissioned testing by Keywords Studios across 13 PCs, from which the three lowest-end hardware configurations were excluded. Players on older hardware may experience different load times.

Which features are missing from the Epic Games Launcher Preview?

While the preview includes core store, library, and download tools alongside new library collections, it currently lacks several account management options and full social controls. In the current build, the social sidebar cannot be resized or closed.

When will the new launcher permanently replace the existing version?

Epic Games has not announced a final release date. Company executives stated that the legacy launcher will remain available until the preview build resolves early bugs, achieves stability, and reaches feature parity with the original client.
