Quote - So far the SR3 is causing my Poser 7 to act weird.  The Material room is acting retarded. It's reaction to any clicking is very retarded in time. Before it would respond within 1 to 3 seconds, now it's response is retarded to 15 seconds to 2.5 minutes.

Do you have an ATI graphics card or chipset? If yes, then please update your graphics driver. If you deleted your preferences during installation of SR3 and the problem appeared, then you might have previously had the workaround for the driver problem enabled that we shipped in SR2.1. You could still do that, but at this point it's better to just get the improved driver from ATI/AMD.

Quote - Rendering four threads is strange to watch now. Before it would render as normal, now it splits the screen into quarters and render each quarter seperately . Strange but usually gets the job done..

Rendering in four threads was always done in four quadrants, no change there. If you had 'Render in separate process' enabled previously, it might have looked like it did it all at once due to how the results are read back.
