return to the  old values in constants in pixelshader, the old values give mi 3 or 4 fps more,(maybe some kind of compiler optimization) in some games and with the current algorithm i notice no difference with this values, please report any problem.
optimizes SSAA to make it a little faster and, the quality should be the same but with a little speedup.
change the way the frame is processed depending is xfb is enabled or not to make this a little faster.
please test and report any problem
