Far Cry 2
FarCry 2 sees the HD 5870 repeating its success in Futuremark by leaving the GTX 285 in the dust by as much as 30%. The lowest performance difference between these two cards was 12%.
The performance gap between the HD 5870 and HD 4870 X2 varies. The HD 5870 loses by 14% 1920x1200, but seriously shines at 2560x1600 with antialiasing on, as it beats the HD 4870 X2 by 9%.
Thanks to DirectX 10.1 support, HAWX really likes AMD Radeon cards. With DX10.1 support enabled, the GTX 285 suffers a tough defeat. The HD 4870 X2 ends up about 23% better than the HD 5870.
