bugger all displacements I guess. On is just a cloud test with a power fractal terrain, the other is a bit more complicated... 2 cloud layers, tree, a smattering of surfaces although only 1 with a small displacement and a power fractal terrain... but still a bit of a surprise. RAM at 12Mb and 22Mb now with about 1/2Gb VM each.
I guess it shows how much of a strain functions and displacements are. Both renders are at detail 1, AA 4 (no GI).... ahhh, both were rendering sky. One render has hit the ground now and up it goes...
It must have shovelled as much as possible off to VM when it started rendering
