Regarding gradual performance degradation while flying

[AlarmedBread]

BETA Patch v 1.03.15527 (Has happened in all versions of the game so far)

There are no issues like this using a single card. Trouble shooting has gone as far as using a clean install of windows.

I have the same issue with crossfire, the game starts out running great and after a while the frames get capped and GPU, CPU usage decreases. Paging file and system RAM start to fill up as this goes on. The only difference for me is that online frame rate stays average of 10fps with crossfire enabled and I have never been able to get decent frame rate online with crossfire on.

I am using a single 1920x1080 screen during testing. Starts at 80FPS average, after red line drops to 10FPS average. Regardless of in game video settings it eventually drops.
