The edges are stupidly overdrawn and visible, it makes the game look like...like...mud. Just mud.
I'm not even sure how to replicate it because i'm the only one getting it, as far as i have found.

Operating System
Windows 7 Ultimate 64-bit SP1
CPU

Do you have shadows enabled? If so, try turning them off.

Move the settings.cfg from your SM folder and start the game with default settings and look if that changes it.
Change the VBO Bulk mode settings on/off and mem size as tests
