[Hang/Crash/WTF] Super DoF

When I press the ‘render’ button, I get some crappy gray crap (like a cut-out corner on the screen) and GMod hangs.

My GMod is legal and up-to-date.
-Windows 7 Ultimate SP1 x64
-AMD Phenom II x6 1055
-Zotac GeForce GTX 470
-4GB Ram
-MoBo is Gigabyte GA-890GPA-UD3H Rev 1

Turn multicore rendering off.

Thanks, I will try this later.
