I have a very good system. During early release, I was <15ms latency and 90-110fps on maxed settings.
About 2 days ago while questing on Taris, my FPS would drop to about 5-10fps for a split second about every minute or so. It was kind of wierd and I could not figure it out.
Nothing else running the backround, nothing effecting my internet connection.
I will try to adjust some settings to see if it stops.
