Well RedPhantom, you're way ahead of me. I don't even have an idea yet. lol

I'll give it a shot, now that I've got Poser working again.

I found the problem and now OpenGL works perfectly, and guess what it was??...

.....It was Stardocks WindowBlinds.

The program must put some kind of transparent overlay on the desktop which was causing the problem. I got the idea when I noticed that every time I opened Poser there was a split second screen flicker so I unloaded WindowBlinds and ended the wbvista.exe process, restarted and poof the problem was gone. So now Windowblinds is uninstalled untill I can get a hold of support and see if there's some sort of workaround/patch.

Thanks for all the comments and suggestions guys, they're much appreciated :)

Quote - I have an ATI HD 5700 and no such problems. Unfortunately, I can't help you because everything worked as expected "out of the box", and I never had to tweak my settings. But I doubt that it's an ATI/OpenGL compatibility problem.

What driver version are you using for your card? Mabey I can try the one you're using and see if it makes a difference.

...and as far as working out of the box, my ATI/AMD Sapphire HD 5770 Flex works perfectly in everything except any form of Poser [Poser Pro, Poser 8 and Poser Pro 2010 64bit, yes I have all 3 installed] and DAZ|Studio.

OpenGL is OpenGL, it shouldn't matter what video card is used.

My previous card, the ATI X1900XT worked just fine using the last available legacy drivers. I only upgraded because of a couple of DirectX 11 games that I bought.
