I'm having problems with running X-Wing Alliance in 3d Hardware mode. I've tried everything and I can't seem to fix the problem. The cockpit's are showing up corrupt, as well as the lighting all around and ships appearing/disappearing sporadically. I've tried various setting changes and I've tried uninstalling it to see if that would help, but it doesn't. I will try and have a picture in a few mins.
  System stats: 
 Intel Core 2 Duo E6400 2.13ghz Processor
 eVGA GeForce 7950GT 512mb PCI-E Video Card
 Nvida Forceware Version 162.22
 2gb DDR2 667 RAM (2x 1gb)
 Windows Vista 32-bit Ultimate Edition
 Screen Resolution: 1280 x 1024 
 I've also downloaded the lates DX drivers but to no avail. Please help! 
 Edit: Picture added. It doesn't show in great detail what the problem is but I hope it can help.
