Benchmarks: Unreal Tournament 3
The Radeon HD 4850 was only slightly faster than the GeForce 9800 GTX in Unreal Tournament 3 with AA/AF disabled. This allowed the new GeForce 9800 GTX+ to overtake the lead with a small 5fps victory at 1920x1200.
Turning on 4xAA/16xAF did the Radeon HD 4850 no favors in Unreal Tournament 3, as it was now slower than the old GeForce 8800 GTX, granted by a very small margin. This placed the Radeon HD 4850 10fps behind the GeForce 9800 GTX+ at 1920x1200.
