Lo-Fi Games

I've started getting some graphical glitches. See attachment.

Not sure if it's something I triggered. I did upgrade my radeon drivers from 12.x to 13.x, but the game was working fine for several hours after that update.

I don't recall changing any settings immediately prior to this issue starting, but i tried changing them to see if it made a difference:
FSAA: 0 and 4
VSync: No and Yes
Windowed mode, and full screen
I've tried changing the in-game settings (fancy shaders, terrain cutting, force single threading).
I've tried importing my crew to a new game, and starting a new game altogether.
I tried a computer restart

computer specs:
AMD Radeon HD 6800 series
windows 7
intel i5 processor.

Any suggestions?

p.s. Bought this game today, and looking forward to 0.40 .

UPDATE: This seems to have fixed itself for now. Don't know why or how - it was playing up, so I just ignored it, and about half an hour later I'd noticed the glitching had stopped. I'll post again if I get any more info.

Do you have any sort of temperature monitor available for your video card and/or processor? If so, try watching the temp if it happens again. Your card might just be overheating as you said it was running for a few hours before this happened (mine overheats because it tries to post too many frames when playing low graphics games like Kenshi).

Other than that, maybe the new drivers broke something.

My CPU and GPU temperatures were both below 60 C which is normal.
