Valve has updated the Steam client with startup performance improvements to counter speed claims from Epic Games. The patch reduces desktop launch times while introducing modular achievement groups that prevent game expansions from wiping completion milestones. The update is currently rolling out globally to all desktop users.
Epic Games recently debuted a redesigned launcher running at 5.47 seconds compared to the standard 10.07 seconds on Steam. Valve responded with a performance patch targeting client initialization. Independent community testing shared on X by user girlglock registered a 5.23 second launch time for Steam. Testing conducted by PC Gamer produced different results, measuring Steam at 9.32 seconds and Epic at 5.98 seconds. Real world boot speeds continue to vary based on local storage hardware and system configurations.
Valve added a beta system that splits achievements into distinct categories. Developers can separate base game trophies from expansions and seasonal events. This change ensures that extra content releases will not strip players of their 100% completion badges for the original game. Early support includes titles like Portal 2, Left 4 Dead 2, and Forza Horizon 5. Big Picture mode also received a Big Art Mode home screen toggle alongside a customizable screensaver system that plays user screenshots or a retro bouncing logo.
The update introduces Pyrowave, an experimental video codec for Remote Play that delivers low latency streaming over high bandwidth connections. Desktop Linux installations now run Windows game binaries through Proton by default. Controller firmware updates add a 2nd pairing slot for Bluetooth connections, while Steam Input received improved layout configurators and better sensitivity alignment between the Steam Deck and Steam Controller.
