I need some help regarding viewport performance in blender. It seems like it should be higher for my computer but I can’t figure out why or if I am simply expecting too much.
I have a quite high poly model (340 000 faces) and blender shows that it takes up around 250MB of memory which doesn’t seem much. And even though in solid mode manipulating it is smooth, in edit mode it gets choppy. I have a geforce 570 card with 2.5GB VRAM and 16GB system RAM and somehow I think I should be able to work without any lag with even higher poly count meshes. Am I wrong? I tried playing with other files with face counts reaching 3M and then even the solid mode became laggy while blender was reporting only 650MB of memory usage.
Am I missing something here? Can anyone tell me what can be done to improve the performance by playing with some settings within blender or even in windows (windows 7 64bit) or explain the behavior to me if this is how it has to be? I would be very grateful.
The strangest thing for me is that while in cycles rendered view the performance is much better than solid/edit mode. Why is that.
