Performance in Simulators

Colin McRae Rally 2005

The Radeon X1900 XT CrossFire is almost as fast as the Radeon X1800 XT CrossFire in nearly all the modes and resolutions even though this game is favorable towards ATI?s Radeons. Well, all the virtual racers should anyway rejoice as CrossFire technology ensures an excellent performance everywhere in this game. The GeForce 7800 GTX SLI looks well with 8x antialiasing in resolutions up to 1280x1024 and offers a playable speed in 1024x768 with 16x antialiasing.

The main performance-limiting factors for the Radeon X1900 CrossFire are its texture fetch speed and memory bandwidth which are the same as those of the Radeon X1800 CrossFire.

Pacific Fighters

The performance of ATI Radeon based graphics cards is not the most optimal in this game because the engine of Pacific Fighters was originally developed to fit well the architectural features of GeForce 6 and 7 family cards. It uses the vertex texture sampling and the textures are sampled frequently, so the GeForce 7800 GTX and 7800 GTX 512 deliver the best performance here.

The GeForce 7800 GTX SLI is on top until the Super AA 14x/SLI AA 16x mode where it loses its ground due to the complexity of this antialiasing method and the low graphics memory frequency. The Radeon X1900 XT CrossFire limits comfortable play to 1024x768 with enabled 14x Super AA.
