Thanks for instructions! For future reference: 295.33 - no problems (full performance) 295.33 + nvidia-blacklist-register-mapping-290-295.diff - no problems (full performance) 295.40 - regression (drastict performance loss) (by drastic I mean, from 1400 fps to 5 fps in glxgears, or from 50 fps to 0.5 fps in Counter-Strike 1.6 under wine).
