Performance Degradation with 1.14.5.0. Upgrade

Pre Update: Mix between High and Ultra Graphics between 25 - 40 FPS with Custom FBW at 3rd party addon Airports frequent stuttering, but not that visible while flying Post Update: 10 FPS already on the world map between 18 - 25 FPS on the same conditions as above now also “limited by GPU”, before only “limited by mainthread” Unlucky, I can´t fly anymore.
