High Quality AA and AF
Our high quality tests let us separate the men from the boys and the ladies from the girls. If the cards weren't struggling before they will start to now.
AA and AF performance is a little surprising. While the fact that Aliens vs. Predator numbers are unplayable, we can see that Mafia II performance at 55 FPS is pretty good.
You might want to move back to 8x AF or around that mark and you could enjoy a 60 FPS average with these settings. With strong Mafia II numbers, it comes as no surprise that performance under FarCry 2 with AA is quite strong with a 41 FPS minimum.
