FYi, if you can't launch the game due to a Vulkan error ("ERROR_OUT_OF_DEVICE_MEMORY"), switch the renderer to DX11 using the launch argument:

+r_rhirenderfamily "d3d11"

You can add this under Manage Installation > Configure > Features > "Custom Executable/Arguments". Duplicate the exe for another listing ("Duplicate" default), then add the argument above and name it "DX11" or such. A menu will be available next to your play button with Additional Executables and the DX11 entry you just created.
