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.
Far Cry 2
At these intense settings you can see that both cards sit quite close together, which is a bit of a surprise. We saw this in our non AA tests, though, at 2560 x 1600.
World In Conflict
Both of these cards aren't really built for high resolution AA / AF gaming and we can see while the HD 4830 does again lag behind, the HD 4850 still struggles to offer a playable setup under these settings.
Left 4 Dead
We again see the HD 4830 lag behind as expected. Again, though, at these settings a 28 FPS or 35 FPS average isn't playable.
