They feature Formac's LCD Shutter Technology and support RAVE and OpenGL games. Also, you can use them for any 3D application, not just games. We put the ProFormance 3 through some vigorous testing and benchmarking. We used MacBench 5.0, Quake 3 Arena, Unreal Tournament, Quake 2 and Unreal. All tests were done on a clean install of Mac OS 9.0.4, with Virtual Memory turned off, and the latest versions of all the games.
Longer bars are better.
The ProFormance 3 dominates this test. It is by far the fastest 2D card I've ever used. My copy of Photoshop begged me to keep it instead of sending it back after I was done testing. In this test, we can see that the ProFormance 3 does fairly well, besting the ATi card. However, the Voodoo3 runs away from the pack with a whopping 53.8 fps.
