Hey guys!

I've got a brand new computer with ATI Radeon 5970 HD which has two GPU.
When i check MSI Afterburner it says GPU1 usage is 0% and GPU2 usage is 90%-99%

I have no problem in for example BF3 and I have the newest drivers.

Just found a solution.

I played in Windowed (Fullscreen).
I changed to Fullscreen and now it works with both.

Also vertical sync only works in Fullscreen.

This needs to be fixed!
