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.
Resident Evil 5
With the detail cranked right up including AA and AF, we can see the HD 5850 does fall below that 60 FPS average we want to see. If you look, though, we're not even an FPS away from it.
Far Cry 2
With the detail right up under Far Cry 2 we can see both HD 5800 series cards struggle to break the 30 FPS minimum we want to see.
World In Conflict
Like Far Cry 2, we again struggle with the minimum and getting close to that 30 FPS mark we want to see.
