This game is a Gaming Evolved title. First job for those developers is to unoptimized everything for nVidia user:
DX12 is broken and brings my card right to a crash. On the other hand i can play Gears of War and Rise of the Tomb Raider for hours without a problem...
"Shadow resolution" is just there to load the graphics card with literally no visual difference. Turn it down from "high" to "medium" and your FPS will jump. Dont believe me? Look for yourself:
High:
Medium:
High:
Medium:
The first training mission is the worst. "Shadow resolution" is mostly responsible for the performance problems on nVidia hardware...
