Built in performance metrics would be very useful. If we at least could get an in-game fps and frametime counter.
We should also be able to disable the autosaving since it causes a split second freeze. That's a disaster when driving. Until you fix the streaming system and low cpu/gpu usage at least.
You can adjust Autosave under the 'Gameplay' Tab. Gives you a Full range of Options. Never bothered to disable it yet. Still, given that Option configs are possible, it should also be possible to disable the Autosave feature via that
