Yeah im using fullscreen, i got better performance with pseudo because then it disable crossfire, there is plenty of games what doesen't suppot crossfire but this is first game with crossfire is poorer than 1gpu same card, CRAZY. I mean crossfire doesen't need straight support to work faster than 1gpu same card, this is first game when crossfire is slower than same card with 1gpu.
With pseudo i cannot use vsync and i got terrible tearing, this is reason why i use fullscreen.
