[Perfomance] DirectX 11 Create GPU Device

Recently I was wondering why there were such fierce performance problems on my PC build.
I started the game with a profiler and to my horror saw an absurdly huge number of calls to create a GPU device in DirectX 11.
This is very similar to the bug and the main reason for the fps drop on my build:

  • RTX 3080
  • i7-7820
  • 64gb ram

It looks very much like the game is trying to recreate the GPU device every frame. If you believe third-party sources regarding such a problem, then this is a bug directly with DirectX 11, probably related to an error in the execution of some shader.
