Also, to confuse even more, older games like those for Dx7 don't work properly, and some of the games run misteriously faster on the opengl than on d3d, even if most of most of the cards (that you buy for a PC, not for CAD), are first DX compliant, then OpenGL.
Also, the good old Unreal Tournament is a good test for how compliant the cards are: GeForce make for some strange Z-buffer problems and flicker when moving near lights, Radeon is having problems with the detail textures, which appear and dissapear sometimes, and even the overall look is not very good.
On contrast, you have to admit that each and every card runs extremely whell on 3dMark2001, Quake3. Never seen a card to have problems with these tests, since Quake3 and 3DMark is what sells the card. A few fps more in these games and the PC magzines notice and give 10+ score. Better performance in a game as NFS HP2 would bring no reviews.
More, all the cards can do a type of BumpMapping, and although it is a basic thing that enhances the realism in games (used in Max Payne, Slave Zero), hasn't been used in race games, in fps (Quake3, Unreal Tournament 2003 seems to lack it also, Alien vs Predator). Even a simple 1 channel bump mapping can increase the realism when you look at a paved footpath.
To make problems even more complex, lot of games use 32 bit color, but as a test proved on the Banshee, nor the Quake3, nor the Vice City nor the Serious Sam (1 or 2), put such a big difference when changing from 16 to 32 bits on another card than 3dfx. On 3dfx, even if no 32 bit is available, the filtering and way of working makes that you see no artefacts on smoke and fire, even if Nvidia and ATI are doing it...
Most of the games are 24 bit color, not 32 bit. 24 bit means 8 8 8 in R G B. The 32 bit mean that an alpha channel would exist in the parameeters, and you would see realistic bump-mapping, different as the light is casted on the object, which obviously never used in a game until now... So true 32 bit games were near sure never released until now, with the danger of broking some hearts...
