More Hardware Troubleshooting

• We received some more confirmations of Unreal working better on TNT's with the Creative Labs unified drivers using Glide than Direct3D. If you have a Creative Labs TNT card and have having performance problems, try that. Especially if you have under 128 megs of RAM.
• Lots of reports of slowdowns from users with Monster Sound's who have enabled the "Advanced Options / Audio / Use3DHardware". If you're having this slowdown, disable Use3DHardware and try again. Then please email utbugs@epicgames.com and let us know whether that helped. I've seen three confirmations from users that their problems (huge slow down) went away after disabling this.
• Jack and I have been tracking down the performance problems with the TNT on 64-meg (and lower) machines. To our great surprise, it appears that the TNT is keeping duplicate system memory copies of all our textures--we saw system memory grow and shrink in almost exact proportion to our "supposed" video memory texture allocations. Thus the game uses an extra 12-26 megabytes of system memory--a very inefficient allocation of resources. This is a big surprise, because the NVidia guys has always told us this isn't the case.
  
  Problem in my code? I don't think so, but I'd love to be proven wrong. I'll follow up with our henchmen at NVidia and Microsoft and see if we can track this down...
