Odd video problem with Descent 3.

I just installed D3 again a few nights ago and ran it fine in Direct 3D mode. Then, tonight I took it over to a friends house to LAN with and used his monitor. I noticed it looked a tad funky when I ran it at his house and when I brought it back tonight, I load up D3, and notice a grid right across every loading screen, like it is divided into squares. Not only this but none of my command lines seem to work such as the -bumped- tag. I tried it in Open GL and that works fine but I can't run it in Direct 3D. I've also tried it in some of my other games and didn't see any issues. It tried patching the game and reloading drivers. I'm hoping my video card isn't having issues already as I only received it earlier this month. Anyone have this same issue? Direct 3D and Direct Draw tests check out ok.
I'm running an eVGA 7600GT with dual monitors. One is a 22\" Widescreen Acer 5ms LCD and the other, a KDS 17\" Flatscreen CRT.

heh...
Descent 3 is known for \"tearing\" when running under Direct 3D. Just run it under OpenGL and you'll be fine. Besides, D3 runs faster under Open GL than Direct 3D. =P

The grid pattern in the D3 menu system under direct3d is the result of full screen antialiasing running, there is nothing actually wrong with it, just a bug they never fixed.

I think I may have found my solution. I changed a few video card settings and I set it to performance settings over quality and D3 ran fine after that. Even though, games like Dark Messiah and Oblivion run fine with the quality settings. I still can't get bump-mapping to work again though. Did 1.4 disable you from using bump-mapping or something? I have the -bumped- tag in but nothing. I also noticed that when it worked before on this same video card, when I would enter the game using Descent3.exe I would see the effect, but entering from Vortex, I could no longer see the effect and I can't get it to activate. Matter of fact, none of my command lines work entering from Vortex. Even if I set them up in Vortex itself.

Try the "-subpixelcorrect" command line parameter.
Readme.txt wrote:Adjusts for subpixel correction under Direct3D for cards that do not support it. You can tell if subpixel correction is not supported if your main menu initially has lines in it like a tic-tac-toe board.
"-bumped" turns on bump-mapping. Both parameters have an effect only on the D3D render path.
