I'm getting much better than that with a 2080ti. Where is a good place to test?
- Try conflict zones. See what your FPS is when AI is active and then see how it is when zone is done.
- Try high threat settlements (no need to kill anyone but try to scan a Access 2 atleast). Just walk around the settlement and enter few buildings.
- Try attacking (no SRV, just on foot) a settlement and see how it is when you run around.
- And finally the Concourse itself. See what FPS is in hangar and then what is inside when you run around.
My card chokes in this areas. It is not a disaster but it drops a lot.
