Performance in RPG
ATI’s flagship is considerably slower than the cheaper and more economical GeForce GTX 280 at resolutions below 1920x1200 and has a far lower bottom speed at 1920x1200. But it provides a higher average frame rate at 2560x1600 although Nvidia’s card maintains a playable speed, too. Overclocking doesn’t change anything in the overall picture, adding just a few percent to the already high speed of the HIS HD 4870 X2.
The Elder Scrolls IV: Oblivion
The game loses much of its visual appeal without HDR. Although some gamers argue that point, we think TES IV looks best with enabled FP HDR and test it in this mode.
The performance of the HIS HD 4870 X2 improves by 10% at 2560x1600 in the closed environments. At the other resolutions the performance grows by 4-5% only, which is quite a normal consequence of a 50MHz increase in GPU frequencies and no improvement in memory frequency.
