[Wine] Problem with popcap games and more

[Arjitan]

I´m using the latest stable version under Debian 6.0 x64.

most of the popcap games run slow with activated 3d acceleration (ingame).

Wow in opengl mode runs at a maximun from 30fps with all settings to low.

my question is, is that normal or is something wrong with my setup?
blender(linux) runs smooth even with more complexe scenaries.

pc specs:
intel P4 3,2 ghz
ati radeon hd 4xxx  (with latest drivers from ati)
4gb ram

some suggestions/help would be fine.
