I've uninstalled Wine 1.32, downloaded from WineHQ repository, cleaned apt-get, disabled WineHQ repository and installed Wine from Ubuntu Karmic repository. I've found the version stable and the version unstable 1.1.31. Installed the last, I've found more speed, apparently. The cpu % cpu usage remain lower, with peak of 27% during gameplay.
My mistake. Wine 1.32 or Wine 1.31 it's the same. The speed it's the same, and the process it's splitted on 4 cores like 100% of 1 core. Wine seem that have a very bad usage of potentially of my cpu. WOW it's slow, but my cpu it's sleeping. And the problem isn't fixable lowering to minimum effect/graphics and I don't have an bad vga (8800 GT AMP with 190.42 nVidia driver). On Windows the speed it's more fast, because it's use more cycles/clock.
