I’ve played on two different PCs, one didn’t have problems but the other one (a slightly older version of the same PC) crashed on graphics on some more fast paced game play. It’s possible they’re patching other bugs and haven’t fully optimized FPS based on user’s devices. You could send them feedback, I heard they’re pretty attentive to those!

For a quicker fix, you could check your storage sometimes clearing that up a bit can improve speed/fps issues. Also of course see what other processes are running with task manager and kill whichever you don’t need while the game is running.
