i am waiting for the OP to post his CPU temps.. i suspect at the heart of this there may be a cooling issue. "Is Poser 6's OpenGL broken? I have an old MX with only 32MB and OpenGL works fine in Daz Studio and every other OpenGL application I have." on some lower end cards it doesnt display properly. for example my rendering machine has a 128mb geforce 4000mx, which i thought would be more than adequate as a cheap desktop card. turns out that when you load a transparency in poser and have opengl workspace enabled it will not display properly. ill take a couple of screenshots and show you, hang on...
