Card - nVidia TNT2 model 64 PCI 32mb
OS - Windows 98SE
DirectX - 9
Graphics driver - 71.84 (from nVidia website, stated to be the last package which supports the TNT2)

Problems:

Run dxdiag, run direct draw test, when you see the full screen white bouncing square test, you see it flickering.

Also, run a few directx games, eg Jedi Knight & NOLF. Both display corrupted texture graphics.

So, I try other older nVidia graphics driver packages: "66 94", "53 04", "45 23", "40 71". Same problem!

So, I try an even older graphics driver package: "30 82". Bingo. This works. The full screen bouncing square test inside dxdiag works as it should do - very smooth animation, and my two test games mentioned above display their graphics properly.

What is the problem? Are nVidia's driver packages buggy, or is it my fault - have I not tweaked some of the directx options correctly inside nvidia's control panel?

Thanks a lot for any thoughts, best regards, Robert.
