Anyway, I cannot for the life of me get GPL to run nicely. I have yet to find a balance of performance, functional anti-alias, and non-blurry texture filtering.
My best attempt so far using nvidia profile inspector is this:
OGLv2, 50 LOD bias,
32xCSAA (seemingly does nothing AT ALL for jaggy pixels, but anything else means the dials on the dashboard go all wobbly/torn for no reason? Also, something is needed in this setting to enable the transparency supersampling (even though it's called that, it appears to antialias everything.),
8x Transparency SuperSampling (doing all the work!),
16x Anisotropic Filtering (<here's the problem - it looks like a mega-blurry bilinear filter unless I turn the transparency SuperSampling off entirely, at which point the wheels look smooth-ish, but the dashboard and billboards go wobbly. It gets blurrier the higher the antialias value.)
I can rectify the blurry texture problem and the antialias issues by using a 4K dynamic super resolution, but this absolutely tanks the FPS from 60 to 20-30 in training mode.
I have also tried D3Dv2, in which antialias is great, but anisotropic filtering doesn't work, but in a different way to OGLv2. On the road and on walls, I can see 3 lines very close together where texture detail changes drastically, and armco barriers seem to become 1 pixel tall textures at about 100ft.
I can't wait to do some hotlaps with these problems as just a frustrating memory and not hours of potential anger stretching to infinity!
