Sorry to bother you with all my problems regarding blender. But I wonder if there where a way to speed up the rendertime as mine renderer is so very slow. even for simple scenes. My latest project takes forever even when I am trying to make a preview with small resolution. (250*250 pixels) I had it going for many hours and I didn't see any progress. I wonder if its something wrong with my computer or my blender. I have reinsalled blender 2 times to try to fix the problem. I have also tried to maximize the memory as it needs a lot of memory. It peaks at 1,36 Gb and staays there. The system window show the renderer is running.

By the way I got an AMD 2200+ with 1 Gb of ram and about 1,5 Gb of swap file. My graphics card is Nvidia Gforce 6600 with 128 Mb of ram. IU have installed WinMem Optimizer that supposedly should free up some ram by dumping unused programs and file from the memory. The program is runniing in thew background. Could that have something to do with it?
