Wipeout XL works now and Outlaws properly initializes the 3D renderer (mode switches are still painful in Outlaws). They both have some pretty nasty issues with texture transparency though. Wipeout XL has a demo (16-bit installer though): https://archive.org/details/WIPEOUT_201406
Movie playback now works in Dark Reign, Magic & Mayhem and Tiberian Sun (didn't check the others).
Dune 2000 with the latest fan patch works too now. Seems to run pretty much perfectly (this game is much less cooperative with newer systems than C&C95/RA).
Urban Chaos works now. I remember playing this, but I don't remember the awful 20 FPS lock this game has (it is the game though; not dgVoodoo's fault).
Icewind Dale II "works" now. Graphic glitches all over the place though. Not playable.
Postal seems to work perfectly.
I still have 1080p problems in Total Annihilation and I've tested and I get the same problem if I select 1080p in Tiberian Sun or Soul Reaver too.
Basically games have black bars on the left, right and bottom sides. Graphics are distorted. Cursor position is misplaced and reaching the bottom and right sides of the screen is impossible.
Fun thing, I tried "fixing" this by creating a 1918x1080 solution and it worked... Before I even selected/told games to use that resolution. Remove the 1918x1080 custom resolution and 1920x1080 is broken again.
Is it just me? Are 1080p rendered games working for other Nvidia users?
