I recommend you run/show the HUD from MSI Afterburner, and check the VRAM usage when you see the FPS drops.
I've mentioned in other threads that I've been monitoring the vram usage, and on my 8GB vram RTX2070 Super, I get severe FPS droppage and stutter when the game fills up all 8GB.
VRAM gets a clear-out in-game when you do an FSD jump to another system; I've seen up to ~2GB being cleared during a jump. Other than that, the game/game engine appears to have quite poor VRAM management; this becomes apparent when you're in one location for a time. It also becomes apparent when you e.g. call up the System Map and/or the Galaxy Map - VRAM usage jumps up a bit, but when you exit either, it doesn't appear to be the case that whatever vram was needed for those was then cleared.
The System Map in particular seems somewhat problematic with a couple of issues; the aforementioned lack of clearing the vram it used, and it looks to me like some background process or thread for the System Map keeps running even when you exit it - my guess is it's whatever process/thread is started to generate the planet textures when you bring the system map up; it feels like said process never gets stopped or keeps running in some error-ridden condition. I've seen my GPU at 100% utilisation after entering the system map screen and continue to be like that after exiting the system map.
The bonus is these problems are intermittent and occur at random times; I've had playing sessions where everything worked great, and sessions where it got so bad I had to exit to desktop and restart.
tl;dr monitor your vram usage when you notice the fps drops and/or stuttering.
