I'm having unusually low FPS for my system while playing Battlefield 1 with "ultra" settings at 1080p. I have a GTX 1080 Ti (Gigabyte Aorus, overclocked +50MHz Clock, +200MHz Memory), i7 6700k, and 16gb 3200 Hz RAM, but still I get an average of ~100 fps when others with similar builds have been reporting 170 to 180 fps. I've turned the resolution scale back down to 100 and have reupdated my drivers, but still have had ~100 fps in-game. As a reference, I tested my system with Unigine Heaven twice (First with ultra, 2x AA, tessellation disabled, 1080p; Second with ultra, 4x AA, tessellation extreme, 1080p) and got scores of 5732 and 4284, respectively.
What gives?
