Description of my "discovery"
If I run Q3 live normally everything runs ok. I have 125 FPS but game does not seem very fluid (I explained this to myself this way after my ping worsened for some reason on all servers about twice few months back). No system change, no major drivers change.
I installed CrossOver (it was free yesterday ) and checked if it changed performance in Win games run under Wine. Didn't see major change.
But to my surprise if I run Q3 again after Wine game end Q3 runs sooo much more fluid - so fluid I have never seen before (even under Win). How is that?
I can't say if it was actually caused by crossover or it was always like this. Does Wine change something in kernel settings (it is not permanent change, it disappears after reboot).
Can anybody confirm this and explain how does it work?
