Thanks but that's too much of a developers challenge to me. I thought there might be a simple solution that I missed. I can live with the fact that you will not get exactly the same performance in Linux/Wine that you have in XP. But the difference is to high for me (as a regular "user") so I will (reluctantly) keep Microsoft for now. Hopefully the next version of Wine (if thats my problem) will be even better and/or the next Nvidia driver (if that's the problem) for Linux will be better. If I can contribute in any way in the development just tell me what to do (in details since I'm not IT-technician or "Linux-nerd") just let me know.
