Blurry ground scenery in Germany

Hi,

I got the problem that when I fly in Germany, I got a blurry scenery about all over the place, when I use time excelleration like 2x.

When flying with Feelthere B737, my computer seems to be soo bussy with the scenery that computing the aircraft gets hard and I get sudden bank angle warning and sudden movements.

I got a pretty decent computer, as you can see in my signature...

And see the screenshot please.

What do you need to know about my FS9.cfg or anything else, so you'r able to help me here to improof my FS9 experience?

Greetings, Torben
