This game has a very weird and terrible performance. I have Windows 10 Creators Fall Update > Game crashes, have to use W7 mode. I have 980 Ti > Game sometimes runs smooth as butter, but either after sometime or immediately from the start the FPS is just terrible. Changing settings (any) has no impact on FPS. Even lowest settings game still runs 40-50 FPS. I have AMD Ryzen 1700X.
