With the use of Heroic game launcher, I’m wondering if you all preferred to play your GOG version of games over the Steam version. I can go either way but sometimes I pause and think, having two copies of the same game, one on steam and one on GOG, which one would give me a better gaming experience. For example, I may choose the GOG version because I don’t have to deal with pre-shader work being downloaded every so often and support DRM free gaming, owning my games. Take the game files anywhere I go. I can just into my games. Yet, Steam achievements and seeing the game’s metadata is always life: seeing the game info, store page, community stuff about the game, and more all there. So what do you chose? GOG game or the Steam game.
Yes, a lot of games work fine without precompiled shaders. Others, like Apex Legends or Rocket League, are a complete mess (at least for the first few minutes of gameplay - it used to be much worse but DXVK 2.0 helped a lot with this). You’ve probably just only tried the games that work fine.
Have you tried with the newer Mesas (like in SteamOS 3.5)? Apparently it shouldn’t be a problem anymore with the new shader compiler.
