So I noticed a visual bug when running the setting ''Object Details'' on Very High.
Here's some screenshots:

This happens to their clothes and in that first screenshot that ''big alien'' shows up and he has some bad artifacts too.

My PC's specs are:

Intel i5 2500K @ 3.8Ghz.
Ati Radeon HD 6950 Dirt Edition.
8GB Ram.

Everything has the latest drivers, I hope this bug can be fixed....

your setup cant handle very high. you need to turn details down then as its a very demanding game.

what have you got everything set to?

I believe it's a problem with AMD's drivers. Development is a bit slower compared with NVIDIA's rollout of updated drivers for new games.

My setup can handle it pretty well, I run it in window mode and not in 1080P with everything on very high I still get an average of 30FPS, so it runs fine. It must be what Wingless said with the drivers then.
