Hello Umberto
Thank you again for your answer.
The problem for my system really seem to be the dynamic lights. If I disable the P3D, the FPS increase massively. But not in the FSDT Sceneryen. I have tested with all settings, regulator left, Antialaising and I only got minor FPS increase vin max. Up to 3. LM told me that the frams I get with my system and views are very noticeable.
My system consists of:
Asus Maximis Hero III, GTX 1080Ti FE, 16GB RAM 2x 256 SSD and I7 6700 4.0 GHZ. With various addons like CH Pro X, GEP3D and airports.
Best regards
Urs
