SteamOS 3.5 Delivering Some Decent Performance Gains For The Steam Deck
One of the popular games where I saw the biggest uplift with SteamOS 3.5 was Counter-Strike: Global Offensive. Regardless of running under OpenGL or Vulkan, Counter-Strike: Global Offensive saw a very nice speed-up with the SteamOS 3.5 preview.
With more demanding games like the F1 22 racing title there didn't tend to be any significant performance difference with SteamOS 3.5 on the Steam Deck.
Similarly, for HITMAN 3 on the Steam Deck the performance was largely the same as SteamOS 3.4.
