CodeCretures requires a fully compatible DirectX 8 
videocard with preferably 128 MB of RAM to store textures. Codecreatures 
utilizes vertex as well as pixel shaders to run their tests.
The 
CodeCreatures benchmark is all videocard bound and here we see the power of the 
Radeon 9700 Pro.
As the 
resolution goes up, all the videocards start to become bottlenecked.
