I am no longer using any CPU speed control utility, and thats for any of my PCs:
AMD-mil64-2.5 Ghz, P4-2.4 Ghz, P4-HT-3.0Ghz, P4-HT-3.4Ghz, D2C-2.18Ghz
We used to use this throttle down method before this Glide wrapper, but it is no longer necessary
unless you run D3D and not Glide 3Dfx graphics and wrapper.
If you use the DGVOODOO wrapper and set it up as we recommend via the REFRESH settings,
the game world rate will be limited to the monitor's refresh rate (60, 65, 70 hz) and
thus you dont need to throttle down your CPU.
Note also, when you play multiplayer and share a common cockpit (pilot/cpg) get both players to
run the same monitor refresh rate (60hz or whatever) to reduce the amount of visable update blinking
and close up formation winking out of the other a/c when very close.
