I was actually referring to a specific area around BRABANT flying from say Maastricht to Rotterdam. On my highend machine suddenly the scenery goes blurry and very blocky. Also FPS drops through the floor. It doesnt happen in all areas. Infact my standard test flight after updates is LELYSTAD turning right towards the bank of windmills.
No issues there. But some areas in Netherlands are weird.
I believe it has been mentioned somewhere before.
