Epic's vibe-coded launcher preview starts 46% faster than Steam in a test Epic commissioned
Epic Games has released a preview of a rebuilt launcher that it says it vibe coded and calls light on features. The 46% startup lead over Steam comes from a test Epic commissioned, and the backlash so far is posts on X.
The Engineer · Build desk
Epic says its new launcher is 46% faster than Steam from a cold start and 14% faster when restoring from the system tray, which Tom's Hardware notes accounts for 0.06 seconds. Epic commissioned the testing from Keywords Studios across 13 Windows platforms.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Faster than Steam from a cold start, per Epic | 46% | 4 | |
| Faster than Steam restoring from tray, per Epic | 14% | 0.06 seconds, per Tom's Hardware | 4 |
| Windows platforms tested | 13 platforms | 5 |
What happened
- Epic lists "certain social features and account management options" as missing and says it is working toward feature parity.
- Epic suggests Unreal developers and competitive Fortnite and Rocket League players stay on the old launcher, and Tom's Hardware says the reason is unclear.
- One X user advised removing every payment method linked to an Epic account, and Kotaku described a wave of roasting over the vibe-coded framing.
Why it matters
- decision Players with a card on file have to choose between trusting a build Epic itself says could have issues and removing the card, as one X user urged.
- constraint The 46% figure measures cold starts against Steam on machines like the 13 tested, so current users cannot use it to decide whether to switch from the old launcher.
- exposure The reputational cost so far is attached to the vibe-coded label on a storefront that holds card details, and the only reaction reported is posts on X.
The 46% figure is the only measured comparison Epic published, and the comparison is with Steam. Epic says the new launcher starts 46% faster than Steam from a cold start and 14% faster restoring from the system tray [4]. Keywords Studios ran the testing for Epic, in five tests across 13 Windows platforms [5]. For that number to transfer to your machine, the machine has to resemble those 13, cold start has to be the delay you care about, and Steam has to have been measured in the same state.
Existing Epic users would want a different comparison. Tom's Hardware noted that Epic's only statement about its own current launcher is that the new one is "way faster and more responsive" [9]. The "30x faster" claim for the library, on Epic's landing page, comes with no details [9].
The tray number is small. Tom's Hardware pointed out that the 14% gain amounts to 0.06 seconds [4]. If that is the absolute gap and the 14% is measured against Steam's time, Steam restores in about 0.43 seconds and Epic in about 0.37 [17]. In our view a gap that size is hard to feel.
The label is a separate question from the speed. Epic's announcement said "we vibe coded a new Epic Games Launcher that's way faster and more responsive than the current one, and has a new look" [1]. It also says the preview has "advanced digital commerce technology such as a shopping cart" [12]. Epic Games Store general manager Martin Keely described the work to IGN: "So this is a completely new tech stack, a complete new rewrite of both the shell, which has the download manager, library, and the app itself, as well as the new store architecture" [8]. He added that discover and product detail pages have been rewritten too [8]. Kotaku described the storefront as the place where Epic wants millions of players to store their credit card info [13].
Epic did not disclose which parts an AI model wrote, how much, or how the code was reviewed, and none of the reports cite a payment bug or a count of removed cards. Kotaku described a wave of people roasting the framing and said the launcher appears borked [16]. One user wrote, "I would strongly advise removing all payment methods linked to your EGS account if you use one" [14]. Another posted that on day one, switching Fortnite from Performance mode to DX12 opened UEFN [15]. That is a single user's report.
Epic's own guidance is cautious. It suggests Unreal developers and competitive Fortnite and Rocket League players stay on the old launcher [11]. It lists "certain social features and account management options" as missing and says it is working toward "feature parity" [10]. The disclaimer reads, "The new Epic Games Launcher is in Preview for testing, and with any beta there could be issues" [3]. Epic promises those problems will not affect players once they boot their games, most of which were not vibe coded [7].
CEO Tim Sweeney confirmed this week that Epic is retooling for maximum AI acceleration, according to Kotaku [6].
What to watch
- Whether Epic publishes a comparison against its own current launcher, or details behind the "30x faster" library claim.
- Whether the stable release closes the missing social and account management features, and whether Epic stops steering Unreal developers and competitive players to the old launcher.
- Whether Epic says which parts of the launcher, including the store and cart, an AI model wrote and how that code was reviewed.
