The problem we described in our two previous reports on CrossFire still persists. This game still doesn’t like multi-GPU technologies and suffers a performance hit as soon as you try to use them.

The Super AA and SLI AA modes (when the additional GPU is only used to improve the antialiasing quality) work correctly, although we can’t see any speed growth over the Radeon X1800 XT CrossFire. The gap between the two versions of ATI CrossFire is less than 1fps at the biggest.

Quake 4

Like in many cases above, the Radeon X1900 XT CrossFire is only any better than the older platform in 1600x1200 resolution and when extreme antialiasing modes are turned on.

As you see, the balance between the TMU performance and pixel processor performance in the GeForce 7800 GTX is more optimal for today’s games than what Radeon X1900 XTX has to offer. Unfortunately, the low texture fetch speed limits the performance of the new solution greatly in a number of games, including Quake 4 .
