azaiya: if you go to the snapshot in menu, yeah. though it doesn't ALWAYS listen to your size, always double check what it took. sometimes it just takes black screen.
(and there are other potential issues that are sometimes a problem, like it'll calculate the shadows/water/specular in tiles the size of your actual screen, and the tiles won't match up so you'll have all these weird seams. i think that bug is squashed again currently, but it pops up from time to time)
