Tim Sweeney updated the Unreal Technology page with a big update with an explanation of, or at least the confirmation of, the problem where TNT/TNT2 cards suck down an extra 25 MB of system RAM in UT, some cool links, and some tweaks for TNT users to improve performance in the Unreal Tournament Demo. Thanks Frans at 3D Action Gamers. Here's the tweaky part:

TNT Users, Try This!

Tweaks:

• Play in 16-bit color, which is significantly faster than 32-bit color.
• Turn the detail options down in the Preferences/Video menu.
• Use the "-" key to reduce the HUD size.
• In Preferences/Game, turn off the display of your weapon.
• If you have enabled Advanced Options / Audio / Use3DHardware audio support, TURN IT OFF for now! Big driver performance problems.

Experimental improvement for the brave:

• Try NVidia's Beta Detonator 3.34 drivers (thanks to Anandtech's site for the link).
• Try putting this new D3DDRV.DLL into your \TournamentDemo\System directory. Please back up your existing one first!

These two downloads are beta and haven't been rigorously tested yet, but in our gameplay sessions here, they're a huge improvement on low-RAM machines with the TNT, TNT2, and GeForce256.
