Shutter after FSD Jump exit

Heya My GF is playing Elite on our 4k and it worked well in the past time, then we had a hitatus from elite for a few weeks / months, and now (yes updated drivers n all) after exiting hyperspace (when you zoom in on the star) there are very noticible shutters that. She nearly got roasted in a tri star system due to that. Its gone the second you fully arive at the end. Its also barely there on small planets (red giants etc.). The framerate dips to 25 and goes back to 30, but the visible stutter is more like 10 fps :S (we use nvidias fps counter)- it seems to not matter what star she arrives, its quiet random when it happens.

Ive dug around but only found answers to different actual issues (typical if you try to fix a error xD ).

Anybody had this ? Shes playing on a 7700k i7 and is using my old gtx980. Yes its on the limit but the main "wtf" we are heaving is that it worked well previously in the past. - aka the "no fkin idea what went wrong" syndrome.

Any lead would be greately apreciated!
