I was able to run "Quick Outfit Customization" and all the texture mods I installed that shouldn't work without "LML" so i think "LML" works. Here are my launch options "gamemoderun PROTON_HIDE_NVIDIA_GPU=0 PROTON_ENABLE_NVAPI=1 WINEDLLOVERRIDES=dxgi,dinput8=n,b %command%" WITHOUT QUOTES. All this options I found on RDR2 page in ProtonDB.
