I emailed Skuzzy this info yesterday and shared it with my squad. These 5 tweaks directly to my network card made a HUGE improvement for me. I see about 5% of the warping that I used to see, and so far -- fortunately -- no one is reporting that I'm warping. Before these tweaks, I was told that I was warping BIG TIME.
I hope it helps others...
Note that I'm using Vista Home Premium SP1 (64-bit); so, the settings might have a slightly different name on your PC. These are from my notes:
