To update further on my issues, I have solved the graphics glitches in NWN2. I had a gut feeling on this that at some point one of the Nforce driver updates had an adverse effect on my system. I went into device manager, went to the display adapters, update software, browse computer for driver software, let me pick from a list, then I chose probably the oldest driver from that list, the release date was about one year old. I figured I would start there and if I want I can move it forward.
I had a gut feeling about this and after all these years of troubleshooting and building my own computers, testing ram, and so on, working as a computer help desk agent, something was suspicious about this.
Well I can say all the game issues are solved things are back to way they should be, actually seems better now than it has for quite awhile. The graphics are flowing beautifully at cranked settings, no glitches, and so far, crossing my fingers, no BSODs since rolling back!
It makes me wonder about the current status of Nforce drivers? I don't think it is possible to make a driver backwards compatible forever, or is there something else going on here? I'm no programmer, software developer or engineer.
