Video artifacts with nVidia FX5900 card using HW interface

[backinblack]

Hi all. Running AC 2004 on a 1GB machine with a 3.06GHz HT Intel and a 256MB nVidia FX 5900 XT card. When viewing the model in anything other than 2D wireframe, my crosshairs leave trails and line fragments. Hardware is fine, as it does the same with another card. Using Heidi10 and OpenGL8 default drivers. I've tried adjusting settings in the nVidia control panel with no avail. Enabling Dynamic Tessalation and Adaptive Degredation make the problem worse.

Any thoughts?

Thanks!
