Performance in Third-Person 3D Shooters
Lost Planet: Extreme Condition
The HIS HD 4870 X2 speeds up at every resolution when overclocked, but its bottom speed doesn’t change, which means that the card is still limited to 1920x1200 in this game. Well, we didn’t actually hope that there would be a performance breakthrough at 2560x1600 just because we had increased the GPU frequencies by 50MHz.
Tomb Raider: Legend
CrossFireX subsystems work normally in this game after the release of ATI Catalyst 8.8, yet the Radeon HD 4850 CrossFire still cannot deliver a comfortable frame rate at 2560x1600. The HIS HD 4870 X2 feels all right at that resolution. Overclocking just adds it a little more speed. The only exception is the resolution of 1600x1200 where the GeForce GTX 280 is superior for some reason.
