Hi,
Thanks for the replys. I attached a DXDiag output.
I am running Freetrack, Tuneup and Avast Antivirus (which I will now turn off) Tuneup as well? It has a so called Turbo mode but to be honest I never really recognized any difference.
I have tried all settings in Blackshark, low and high and it is almost the same, which confirms your statement that the CPU is the weakpoint and not the GPU. I thought it would be the driver, for this reason.
But it makes sence as under normal flying the FPS is fine with everything high but when I play the "battle" mission or "Georgian War" Campaign than the FPS drops significantly.
Cheers. DxDiag.txt
