Quirks

Together with the community I've found a bunch of quirks with various games. If you're encountering issues, try applying any or all of the suggestions below and see if they fix your issue.

Try these first:

• Explicitly enable VSync in the game settings (and don't override the present mode using lsfg-vk)
• Cap the game at a stable framerate
• Disable variable refresh rate (VRR)
• Disable MangoHud, VkBasalt or any other installed Vulkan layer

For Wayland users:

• Disable tearing in your Wayland compositor ("enable" no-tearing)
• Disable direct passthrough in your Wayland compositor (an option described as bypassing the compositor in fullscreen)
• Run the game in a window

For OpenGL games:

• Try using Zink (__GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink)
• If it crashes/freezes using Zink, you're out of luck :/

For Steam Deck users:

• Launch the game using ENABLE_GAMESCOPE_WSI=0 %command%
• Lower the game resolution and use non-linear scaling in the debug menu
• Wait for lsfg-vk 1.1.0

For 32-bit games:

• Try using PROTON_USE_WOW64=1 when using Proton
• Might not work using older Proton
• Doesn't work for native games

If MangoHud/Steam/etc. doesn't detect generated frames

• There's not much you can do about it except wait :P
