I just switched over to scree3d and it is indeed faster. Though styill considerably slower than P5 it is now at least tolerable to Pose with lotsa models on-screen. But when I try to render with Firefly I still get the message in the picture, even after following the advice. When I try to render with p4 it is much less polite, it just freezes for a whileand then turns white and stops responding as soon as I click it. The suggestion about scree3d was a really good one...... Anyone else have any advice about something I may be overlooking ?
