I know most of you won’t care or see why this is of interest but I got another game, this time No Man’s Sky, working in #SBS (side-by-side) mode using #ReShade [on Linux PC] 🤓
Steam start parameters are a little bit different though, once ReShade was configured for Vulkan:
WINEDLLOVERRIDES="d3dcompiler_47=n;vulkan=n,b;vulkan-1=n,b" gamescope -h 2160 -w 3840 -H 1080 -W 3840 --scaler stretch -f -e -- %command%Apparently there is an open bug for ReShade and Vulkan via Proton but frankly I didn’t quite get the details – it just worked for me: https://github.com/kevinlekiller/reshade-steam-proton/issues/6 – YMMV.
As usual: Viture or XReal users can probably just press fullscreen after switching into SBS mode to watch this. Others may need an external player to sort it out – I sure love delivering to the absolute niche of the niche [of yet another niche] 🤷
