After playing a few hours, FPS drops from 40 to 5FPS

Not sure if this is of any help to you guys, but this just solved all my issues i think. Testing as we speak. I had my monitor in 144hz and geforce settings wernt correct. Heres the link to what helpled me. Now got a solid smooth 30fps locked atm, gpu is now working as it should. Ill test and let you all know if i get any performance drop in the FBW as i normally did. Reproducing yesterdays flight where i landed with only 5fps.
