25 days agoThere’s a specific version of proton to use for RDR2. I believe it’s Hotfix. Do a search for getting it to run on Steam Deck, because I recall there may have been a command line argument to add to get it to run.
Set proton to Experimental.
Set this as the launch options:
WINEDLLOVERRIDES=vulkan-1=n,b %command%


My whole-ass PC got a huge performance increase going from W10 to Arch (SteamOS), and that’s even with using Proton/Wine.
