I think my longest render time was about 11 hours. I can't stand waiting. From these above posts I'm guessing there is NO WAY to improve render times? What a horrible concept! I have a new computer and graphics card, but it doesn't help at all! My renders are usually just for stuff like wallpapers. I don't print out my stuff or anything. The render times have always handicapped me making a real complex scene. It's infuriating! I have one right now I really want to render, but I can't have this thing controlling my computer!!! AH! I use my computer everyday, so is there anything I can do?!?!
