Hi, i have recently installed RedHat Linux 7.1 . It really seems as fast as Glide2 + Xfree86 3.3 . I am happy about that :) .
  In my previous configuration i was running kernel 2.2.16, XFree86 4.0.1, and some version of the kernel module and Glide.
  I have noticed differences in file sizes for the kernel modules. In fact the 2.4.3 module for 3dfx is 50Kb and for the older kernel was 8Kb.
  Can someone clear things out? What is improving performance? The new kernel module? The patches in XFree86 4.0.3?
