for a very logn time, since I first installed ut2k3 when it came out, after many reformats, custom kernel upgrades in both the 2.4 and 2.6 branch, and several mouse changes/port changes from usb and ps/2. changed refresh rates, just about everything I can think of. nothing solves my problem, now that I have explained what I have changed I will explain the problem.

I have good performcance in the game, moving everywhere works great, however only with the keyboard, when I use the mouse it will get glitchy liek it goes a little distance backtraces a bit and goes again. so if I am looking left with the mouse it will go left a bit, then right a tiny bit then continue left and keeps glitching. I have tried various mouse smoothing, exceleration, and sencitivity settings as well.

system specs:

slckare 8.1+9.1+customisations out the wazoo not a stock slack install

kernel 2.6.3 w/ ruby kernel patches (multiple displays w/ seperate keyboards and mice each (problem occured before I used this patch)
