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.
If I had to pick a winner between the X1650 XT and the GeForce 7600 GT, I’d probably pick the ATI option, but both cards perform pretty well here in our Prey game tests. At 1920×1200, the X1650 XT is a bit faster: about 8%. Again though, the ATI X1800 GTO would have been the reigning champion if it weren’t seeing the end of its life.
As for the CrossFire performance, we see good performance gains here; 77% and 85% respectively. Prey, and all games based on the Doom 3 engine, are proving to be very adept at scaling with multiple GPUs thanks in large part to its use of OpenGL instead of DirectX.
