3D acelleration packs in after a few minutes of Neverwinter Nights (windows port)
 

Hi

Does anyone know why the 3D on my Ubuntu i386 box gets all jerky after 10 minutes or so of my Neverwinter Nights game. I installed the game from the windows partition and patched it to run, which it does but just for a short time.
The only other hardware accelerated games i have tried are Tuxracer and Chromium with no problems.
