If Company of Heroes has historically run well on NVIDIA cards, the EGO engine underpinning Race Driver: GRID has run creamily-smooth on ATI hardware. That's still true today, as the HD 4890 XT is between 15-20 per cent faster than HD 4870.

Interestingly, there seems to be some driver-related quirkiness with the GTX 275, because its scores are lower than the GTX 260's - something that should never happen once you factor in the architecture. We observed that the FRAPS-recorded benchmark would display extremely erratic frame-rates, being perfectly playable one moment and practically a slide-show the next, lowering the average frame-rate.
