Hello everyone! Been a while since I've posted - work's been a bear. :( Anyways, here's my scenario. I had been working on this image the other night, and, as usual, when I began my render I shut down all unnecessary services and programs running (basically, there wasn't anything running my taskbar), and set Bryce to use Realtime Priority in terms of Memory Management. Then I killed the render because I noticed something wrong, and as I was working on the image, I noticed that movement of objects was extremely slow and clunky. Opening up the Task Manager again showed that Bryce's Priority had been set to Low, as opposed to RealTime. Hmm. I then set it to High and continued to work. After about thirty seconds, back to clunky, so I checked its priority again and it went back to Low. Hmm :(. Finally, I got the object to where it was at least passable for a WIP render, but I'm curious as to what might have caused this. No software was installed between my previous usage of Bryce and this; Machine Specs are P4 2.53 Overclocked to 2.7, 768M Ram, so speed shouldn't be an issue. Anyone have any ideas as to what might have caused this? I'm not sure if I can replicate the problem and even if I could, I'm not sure if I want to, you know? :) If you've got insight, it'd be appreciated. Thanks!! (Image included so you can see that I wasn't doing anything super-processor-intensive...)
