So I have an issue I've never heard of before.
When using 2300 dpi and 0.32 sens in UT99, I have massive negative acceleration, like the mouse won't track when moving relatively quick. I tried 3 different mouse pads and the issue was the same. At 1150 and 450 dpi, the mouse tracks fine with no negative accel regardless of my UT99 sens- I can set it very high or very low with no issues.
In UT2k4 and other games, using 2300 dpi with any in-game sens works perfectly, with no negative accel.
I've also replicated this exact behavior in both games with different mice (tested both my g5 and ec1 evo at different dpi settings)
It seems UT99 specifically has an issue with high dpi mice? Then again, I know guys like unrealshots claim to use 2000+ DPI, and surely they don't have these unplayable tracking issues. Has anyone else experienced this?
