First thanks for the help.
Unfortunatly it doesn't work, althought the plugin glN64 that I found on the page works alot better then any other plugin so far. The fps is still around 30 thought which is too low to be playable.
I got a GeForce 8800GTS, Intel Core 2 Quad 2.4GHz processor and 4gb ram so my computer should not be the problem(and im using XP).
If you have any other ideas help would be appreciated.
