Troubleshooting DDO graphical problems

[adRyft]

Been playing DDO for a while now. Sometimes the game seems to get... cranky. Observe if you will:

I tried installing the latest nVidia driver and the game was unplayable... it got so bad that the screen was a mesh of noise, with no discernible objects or toolbars visible. I tried running CoD: Modern Warfare and got a crash to desktop after the loading screen.

EDIT:

lots of internet research yielded that it was likely a driver problem.

I scrubbed off nVidia's latest driver (whatever it was that their site gave me) and tried one of a few older driver variants that were recommended to me for my 7600 GT.

So I started by trying the oldest recommended driver, which is 93.71. The game runs extremely choppy, but it runs. And it's clear, with no visual artifacts or glitches visible. I think my choppy results may be intense lag... I tried CoD4 single player and it runs beautifully. After trying to get through early parts of DDO despite stuttering, I got CTD.

I next installed version 169.17 beta. I'm getting the weird visual artifacts again, but DDO runs smoother. Of course, every once in a while the screen now goes black.

I still have to try 178.24.

Any other suggestions for the to-do list? Do you think newer drivers will likely yield better results?
