could it be because i did a long haul in the morning and it was completely fine, and then after i landed, i quite my sim and enabled some other airports via my scenery config as usual, and then did a flight from EDDT aerosoft to LIPZ RFSB no blurries, but when doing LIPZ to LICC other airport without restarting the sim after 120 nm got blurries and then the blurries fixed themselves following a sim crash, 16GB RAM , GTX1080, i7 7700k @4.4ghz, ( i did not restart my pc after the long haul.)
