I'm new to Linux, I've just installed Ubuntu 23.10 and installed civilization VI from Steam. However, for some reason I have maximum 25 fps in the game, when on Windows I got stable 60 fps. I tried to run game with the OpenGL instead of Vulkan using PROTON_USE_WINED3D=1 PROTON_USE_WINE_DXGI=1 PROTON_NO_D3D11=1 but every time I launch game it crashes.

• Name of the game with compatibility issues: Sid Meier's Civilization VI
• Steam AppID of the game: 289070

System Information

• GPU: Nvidia GeForce 940MX
• Video driver version: nvidia 535
