Robert G. I know Michael is a genius. I have talked with him via e-mail many times. I fear by your statement that Quake is optomized for the Pentium you are missing my point. The mix of coding in Quake would be desasterous on a Pentium featuring MMX with a big cycle penalty. I am well aware of the hand optomization in Quake. I have seen "psuedo-code" for the engine. The Cyrix's chips performance (the 6x86) on Quake doesn't worry me, as it was hand optimized for another chip. However, you will probably be seening a bonafide Windows 95 version in the not to distant future. This version will use less (but not none) hand optimized code. This would improve the performance on a Cyrix machine. It would also harm the performance on a machine like the Pentium MMX with the big cycle penality. The point is, while Inel has a good idea with MMX their implementation leaves much to be desired. They should have used a set of dedicated registers for MMX and not shared the FPU registers. Steve
