Prey is the latest title to be released using the Doom 3 engine, and since we have learned how to tweak the engine a bit more since then, it makes sense to include this major title in our testing suite.
Very suprisingly, the X1950 XTX outpaces the 7950 GX2 card by a lot at 2048×1536 and 2560×1600. Even without the multi-GPU advantage that NVIDIA’s card have, the ATI configurations have the decisive win here. In fact, in CrossFire mode, I was able to play at 2560×1600 with 4xAA and 8xAF enabled never dropping below 47 FPS!!
Both Quad SLI and X1950 XTX CrossFire setups use standard AA and AF here, despite the indications on the graphs as the Prey engine doesn’t put any restrictions on the cards. All three setups show GREAT performance on this game even at the 2560×1600 resolution!
