Has anyone else found their screenshots aren't working anymore?

I turned off FSAA, to see how many extra frames it would give me (about 6 at 2560 x 1600) and I swear it looks better.

However, I'm getting more stuttery jerkiness than before. And the white edges on buildings shimmer/glitter horribly. Also some buildings are failing to load now, I'm seeing only their foundations (half a village in one case).
