WINE SLOWDOWN FIX BELOW:
Thanks for the info. I tried with Bottles and Wine GE and 100 different settings.
fsync seemed to help (or placebo), and wine-ge seemed also a bit faster than my normal wine installation.
But since it seemed that those slowdowns only appeared when theres' cpu heavy stuff (lot of flying grenades, shattered objects, ...) and even smaller desktop resolutions made ZERO difference, i looked further into CPU/scheduling problems.
And see: if i use `taskset -c 0 wine` or `taskset -c 0 bottles`, it's 90% fixed.
The multiple seconds long slowdowns are now only microstutters with which i can live.
