The story in short

Epic Games unveiled a "vibe coded" launcher that it says is 46% faster than Steam, and Valve replied with a Steam update that trims its launch time to roughly five seconds.

Epic Games announced on 15 October 2026 that its new AI‑generated “vibe coded” launcher loads the store page 46% faster than Steam from a cold start, and Valve answered with a Steam update that reportedly cuts its own startup time to around five seconds.

What we know

According to GamesIndustry.biz, Epic’s beta launcher is “46% faster than Steam from cold start to the store page.” The claim is echoed by Eurogamer, which notes Epic “admitted to vibe‑coding the new Epic Games Launcher with AI ‘to be faster than the other guy.’” TechPowerUp adds that the launcher arrives with a redesigned library, improved download handling and “no handwritten code.”

Valve’s response was reported by Windows Central, stating the Steam update reduces its own launch time to “around five seconds.” The two companies now appear locked in a performance duel that could reshape the PC marketplace.

Epic also highlighted recent progress on Easy Anti‑Cheat, claiming parity between its Linux and Windows implementations—a point covered in our own piece on Epic Overhauls Easy Anti‑Cheat to Bring Fortnite to Linux.

Why it matters for gamers

Launch speed directly impacts the daily experience of millions of PC gamers. A faster start means less waiting after a reboot or a game‑swap, which can be especially noticeable on older hardware or SSD‑starved systems. If Epic’s AI‑driven approach lives up to its claims, it could pressure Steam to prioritize performance updates, as seen with the recent five‑second launch.

Beyond speed, the AI‑first development model signals a shift in how major platforms may be built, potentially reducing development cycles but also raising questions about code quality and long‑term support. The Linux anti‑cheat breakthrough also broadens the appeal of Epic’s ecosystem for players who prefer open‑source operating systems.

For Xbox fans, the competition may translate into better cross‑play options and tighter integration with services like Microsoft Xbox, especially as all three giants vie for the same user base.
