Gfx.WaitForPresent killing my framerate...

I don’t understand this… It was working perfectly fine last night, and I haven’t changed anything since. And today, all of a sudden, my framerate falls into the 10’s (down from 2000). The profiler shows this:

I had never seen this “Gfx.WaitForPresent”. Some googling resulted in it being something to do with v-sync? I don’t recall ever turning v-sync on. Someone help please! D:

Edit: The meshes in memory seems to act odd during these gfx lags. Maybe that’s related?

Fixed it myself by doing absolutely nothing at all… Well okay then…
