I used 1920x1200 for FC2 and STALKER CLEAR SKY and 1920x1080 for CRYSIS WARHEAD(strage that it doesnt have 1920x1200 option)
Well the results were good for me,i ran FC2 Benchmark tool and i got 60FPS on average,when i had CAT 8.11 i got 49FPS on average.
In STALKER CLEAR SKY and Crysis,well i played a little but i got an 3-4 FPS more,the good thing is that it increases the min FPS too,for example in STALKER when the game starts (probably the most demanding part of the game) i got 19FPS woth 8.11 min now i get 24FPS min
I am happy with the results
wating for final version:)
