I am able to play at 2560x1440 resolution with everything ULTRA (except Textures) very smoothly. If I set Textures higher than "Standard" I get constant texture swapping and as a result the game stutters to the point where it is quite unplayable. My VRAM usage never goes over 1600MB with "ULTRA" textures, so I'm wondering if the texture VRAM budget is too small for this resolution?

Would it be possible for you to expose the texture VRAM budget parameter within the config file to test/improve the VRAM usage?
