ATI's Radeon cards reigned supreme in our 4xAA testing with F.E.A.R. 2. The 4870 X2 delivered the best overall performance, outrunning the GTX 295 by 18% at 1600x1200, but the gap narrows to 2% by 2560x1600.
The Radeon 4870 outperformed the 216 shader GeForce GTX 260 in all our tests, in fact in some cases it's quite competitive with the GTX 280. Between the 4870 1GB and 512MB, we noted a slight performance advantage in favor of the 1GB card, but with the margin only topping out up to 1.3% faster, the two cards are close enough to basically call it a draw. Moving further down the spectrum, the Radeon 4850 easily managed to outpace the GeForce 9800 GTX+ while the 4830 had no problem handling the 8800 GT. The closest fight is probably between the 4670 and 9600 GT, with the 4670 outrunning the 9600 GT slightly at 1600x1200 and 1920x1200.
