Tomb Raider: Legend
Tomb Raider: Legend proved to be incompatible with ATI CrossFire technology: when you try to enable multi-GPU mode, the performance plummets heavily. The quad-SLI system is free from that problem, yet is not very efficient, either. It ensures a performance growth of 15-20%. Owners of a GeForce 7950 GX2 can play the game in the Next Generation Content mode, but not in resolutions above 1280x1024. It is in this mode that the game gives you the highest image quality, so you should better lower the resolution than lose in the level of detail and special effects.
It’s virtually impossible to play the game with enabled 8x SLI AA or 8x Super AA, yet we can note that the GeForce 7950 quad-SLI and the Radeon X1950 XTX CrossFire are roughly equal to each other in this test.
The same is true for 16x SLI AA/14x Super AA mode. The combined power of two of today’s fastest graphics cards is still not enough to run Tomb Raider: Legend with a level of antialiasing higher than 4x.
