Okay. Before I say anything stupid, let me just say that I really know
next to nothing about Pentium optimizations.
That said, I do know that Quake is very floating-point intensive, and the
pentium-memcpy patch uses the FPU to perform 64-bit-wide memory copies. I
would guess that this would put more demand on the FPU and cause the Quake
slowdown.
