aeilkema, I'm not in a bad mood. If I was in a bad mood I would have said something unpleasant. But I didn't say anything even remotely unpleasant. When I see a post that is ignoring facts or seems naive, I attempt to reveal the facts that should be taken into account. Nothing more than that.

Whether somebody is confused about how shadows work, or confused about how business works, or confused about how software works, or confused about how product managers do their jobs, if I think I have a better understanding than is indicated in a post, then I reply. As I did here.

The only logical thing to do about OpenGL problems is to work with SM to solve them. The quote you quoted actually began with an illogical question: Has anybody reported them officially? Obviously the right answer is: If you have this problem, YOU should report it. The answer then is yes, it was officially reported. Then maybe ask here if somebody else has the problem and has found a solution.

Moreover, if you read the feature list of the product you bought, it says quite clearly:

OpenGL Preview Improvements
Real-time preview engine improvements in Poser 8 now display lights and their accumulated values more realistically, sorted by intensity. The light properties control allows the user to select each light they wish to illuminate the scene preview. Mip Map support has been enabled for enhanced performance when previewing large textures. Together, these real-time preview engine enhancements let the user view larger textures and offer more complete scene previewing when setting up lights.

See that? View larger textures, more complete scene previewing. That means more data stuffed into the card, and more horespower needed from the card to display the higher quality preview. You even said it - simpler scenes, no real difference. More complex scenes, it is slower. Duh. Of course it is.

Also, there are settings you can adjust to tailor the preview rendering, in case your card or driver are not up to the task of what P8 demands, even if they were good enough for P7. Have you looked at any of these? I'm guessing probably not. In particular hover over Preview texture resolution. It says: lower settings = better performance.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
