Which DirectX Version (10, 11 or 12) is recommended to use, if you want to have a low-poly game with shaders, shadow and aliasing. But not normal or height maps. Moreover my question is, because once we upgraded from directx 9 to 11 now, the GPU usage for the game was like duplicated. I can not even play it with CPU at all. It means directx 11 has higher usage even then 9.
If using Directx10, could it help to decrease the gpu usage? (Which was caused by directx upgrade)
