scrobbling works for me, and the game appears to be a lot faster. especially the premium mode has improved, it's nearly playable on 4xAA, maybe a little jerky. no go with the official version with my graphics card (GeForce 7600GS/256MB with Omega Drivers). enhanced 8xAA is superfluent =)
great work there. still annoyed by the pixel-shader-blur though
edit: just noticed, in premium mode in a few cases (nearly) the whole tunnel-texture seems to be rendered, not just the white parts. looks like a square with a hole in it. I don't know if this has happened in the official version, as I have never played on premium before. on enhanced everything is fine
