Update:
1: Bilinear filtering and dithering works only in window mode - DX10
2: Automatic fullscreen doesn't work, need to switch manually - DX10
3: Bilinear filtering cause glitches and slowdown - DX9
4: Framelimiter works only in fullscreen - DX10
5: Framelimiter works only with internal SPU - DX9
And yeah, it is slow, I have speed issues with my Athlon X2 6000 at 3.1 GHz. Hardware acceleration would by nice.
