Attached Link: RivaTuner

Hey Kawecki, you're a technical guy - could you answer me a question please? I downloaded this freebie app, called Rivatuner, which is an overclocking/tuning app for Nvidia vid cards. I have a GeForce 7600 which is already pretty quick, but this program sped it up pretty well. I played around with the settings with Lightwave and the game Oblivion, and it did real well.   Then I tried it with Poser 7, and although the preview display sped up somewhat, it caused P7 to crash the second a render was finished. I tried it several times, with different figures and props and so on, each time with the same result - Poser 7 just crashed. Not a hang, but just *poof* - gone.

Any idea why, or what could be done to prevent it?
Also, due to other things I've seen, it seems that P7 completely takes over my video card, so I'm wondering if they have some sloppy OGL programming going on in P7.
For example, I often have LW and Poser open at the same time. if I open LW first and load something, all is well. But if I load Poser 7 first, then LW, the OGL performance in LW is horrendously slow. I don't know much about it, but I wonder if Poser simply hijacks everything it can get ahold of in the video memory and takes over the whole vid card for that matter.
