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 Nvidia GeForce 9600 GT is somewhat worse than the ATI Radeon HD 3870 as its speed may bottom out below 25fps in open scene at a resolution of 1920x1200. This is hardly noticeable, though, so the two cards are equals as concerns playing this game.
