I am sure this is a problem with my RAM, but I remember higher resolutions working for me last year, same comp… My ram is 4G, shouldn’t that me enough to handle this?
Yes, this happened to me a while back, and I am not sure why. Either try a newer version, or it could be a video card problem. I have a really old ATI and it is always freaking out in blender and maya. I also have 4 gigs.
