--- Comment #6 from andy andy86@fastwebnet.it --- Thank-you and Sorry. That's because I install most of my games trough Steam, and Steam install game in same wineprefix where is installed itself.
Install every game in different prefix require to install one copy of Steam for each of those wineprefix. :-(
But i don't understand what game installed starforce... probably I already unistalled that game. :-\
Now i run SF official removing tool and wine performance is visibly increased. :D

Also I included complete log because I had to disable normal log in /etc/environment when some game generated biggest log that slowed itself performance. O_o
