Report : tri and quad GPU systems

Enemy Territory : Quake Wars

While Quake Wars is based on the Doom 3 engine, it has undergone some evolution such as mega texturing which facilitates the work of artists; however, there is the additional cost in terms of decoding and access to mega textures. In the end, Quake Wars is a little more resource heavy than Doom 3 or Quake 4.
We saved a demo in a sequence versus 4 bots. Given that artificial intelligence was not calculated in the time demo, results were less affected by the CPU than in actual gameplay or at least in this case versus our bot adversaries.

All parameters were set to a maximum in the game including 16x anisotropic filtering. The patch 1.2 was used.


In this first test, SLI does better than CrossFire which with more than 2 graphic cards doesn’t add any gain. Triple and Quad SLI, however, are CPU limited especially in 1920x1200.


Once antialiasing is activated, the three GeForce 8800 Ultras surpass the two GeForce 9800 GX2s in 2560x1600. This is probably due to the fact that they are handicapped by their memory limited to 512 MB. Triple and quad CrossFire do not function correctly. It’s probable that the OpenGL driver is not yet "CrossFire X".
