This is a known bug or more likely a series of bugs and optimisation issues that is still being tackled on Frontiere end. I get the stuttering sometimes as way.
The only stutters I get are in the hyperspace animation. Check your graphics options and see if the framerate limiter is on as I have seen claims it can cause stutter.
my keyboard is having conection issues, when im near any orbital mass including planets and station of any kind my stuttering gets worse. and it looks like im fast forwarding in small bits
this doesnt happen on my other games or the multiplayer ones (arma 3)
and my ping 9, 25mbps download and 6mbps upload.
i did the whole firewall process and put avast in gaming mode.
