Hey,
it happened to me too for unknown reason although it wasn't often.
Mainly on Eos and Voeld, others planets were fine.
Maybe once in the tempest.
I think it's due to an optimization problem and not a driver issue.

Or it could be like in most Frostbite engine's game, due to auto save when having two different Hard Drive.
I had this problem in Mirror's Edge Catalyst and Star Wars Battlefront.
It was due to the auto save. Game was installed in E:\ (HDD) and save would go on C:\ (SSD).
Many people have reported similar problem and changing the save folder fixed it.
However sometimes it was just the speed of the harddrive not being fast enough.
Try to check that but I won't promise it's the issue there.
