I still have not configured MTRR and -dga doesn't work for me.
in this connexion -pp 15 already perform not real-time decoding
but I've not found any visible difference in picture quality,
althrough something is changed, undoubtedly.
Thus -pp 0 is better key for me. ;)
But problem with sharpness looks like image is scaled without antialiasing
(mean boundaries of diagonalled object is not smooth and have little steps,
althrough under windows - all fine).
Maybe win driver uses hardware scaling or something other tricks?

3D performance is on main goal for me ;)
But in the future I'll tuneup and this feature.
