Hi,for me it helped to update the nvidia driver from 182.46 to 197.13. I have the GTX260 and also had at some places (EDDH) a lot of spikes. I was surprised, but the new driver helped a lot on my system.With BP=0 I have a big improvement in FSDT KORD with the CS757 and Full AI. FPS increased from 8 to 14 (looking to the AA terminal).BUT now I have the black screen problem after clicking the menu :(
