It’s an old problem that FS hasn’t been able to pin down:
It’s gotten even worse for me this patch with the game eating up VRAM while I’m in a party and in the Mourningstar or just entering any menu. I have to restart the game after every couple of games. For reference my specs are:
i7-10700
3070 8gb
32gb RAM
UWQHD screen
It’s hilariously bad when the game sits at 30 FPS and below looking at a static talent tree screen. I’ve noticed that the performance sometimes recovers when I’m by myself and successfully matchmake.
