Quake 4

In 1280x1024 the CPU limits the system performance. However in 1600x1200 GeForce 7900 quad SLI doesn’t show any remarkable results yielding quite significantly to GeForce 7900 GTX SLI and a little less to Radeon X1900 XT CrossFire, which both sport only two graphics processors! However, all systems here perform at over 110fps, which would be more than enough for any first-person 3D shooters fan.

The new Nvidia solution manages to finally leave behind Radeon X1900 XT CrossFire and catch up with GeForce 7900 GTX SLI in FSAA 8x + AF 16x mode. In this case all multi-GPU systems again cope successfully with the workload and reach 100+ fps in 1600x1200.

GeForce 7900 quad SLI manages to perform better that dual-GPU SLI system in SLI AA 16x in 1600x1200. It is about 50% ahead and 89fps is a very good result keeping in mind how many resources the SLI AA 16x mode eats up. However, we clearly see than in the Quake 4, which engine is very favorable to the GeForce 6/7 hardware, Radeon X1900 XT CrossFire system is 10% faster compared to the GeForce 7900 quad SLI!

Although Quake 4 is a relatively contemporary game, it doesn’t demand much from the graphics subsystem. As a result, GeForce 7900 Quad SLI can show acceptable results even in the extreme anti-aliasing mode – SLI AA 32x, but only in 1280x1024 resolution. In 1600x1200 the average performance of the Quad SLI system drops below 50fps. It is definitely not enough for comfortable gameplay, because in scenes with complex graphics and plenty of enemies the performance can drop dramatically. Also, we should remember that there are slight SLI AA-related artifacts in the Quake 4.
