Hi, I noticed there's a thread
for Thief and SS2 (which are based on the same engine btw (except Thief3)).
P.S. I just noticed that the last post there is yours
I did some testing with my 7900GTX last year, and I can confirm that NFS5 works OK, although the 3D effect is not as great as I had imagined. I can't comment on Quake2 exactly, but I played a bit of Kingpin, which uses the Q2 engine, and it was pretty good.
NFS6 is DX8.1, and it should work with modern solutions, I tried it with iZ3D a few months back, and it's mainly OK, with the exception of car models - they are all rendered as big white boxes, pretty ugly sight
, and this makes it unplayeble for my standards. I also remember trying Thief 3 with iZ3D (the game is DX8) but unfortunately the lighting was buggy, or the shadows, can't remember exactly, but it was ruining the game.
BTW, NFS2SE works fine in 3D with Glide->DX wrapper
I think the latest Nvidia drivers with OpenGL support or Dx8 or smth. were for GF7900.
I think they support DX9 as well, or at least partially, I remember playing Oblivion, it was quite buggy if I remember correctly. Oh, Condemned was pretty good with this legacy driver, and it's DX9c I think.
