[Solved, but new question @ latest reply] REPEATING SCROLLING LINE OR SCREEN TEAR

[slickkwilly]

I have seen one post that claimed something like this and said it was fixed by forcing v-sync, but I was not so lucky.

As soon as the opening screen comes on a bacaward z shaped line that goes from left screen to right screen starts scrolling upward from bottom to top repeatedly. Sometimes faster than the last one. I can see what was the previous or maybe the upcomming sceen in the line. The line is about a quarter inch thick.

kind of the thickest screen tear i've ever seen. It is also bright, so if the screen is a dark or black, I can see bright and all objects with in the long backwards z.

Please help here.

oh and it does not happen in windowed mode.

windows 7 64bit, geforce go 7950

I have updated my drivers, which solved the darkness problem. I have turned every setting on and off and I cannot figure this out.

Been at it since 9am and it is now 11pm.

I downloaded pnumbra demo and does the same thing. no other opengl games I run do this.

any ideas?
