Thie game has a major slowdown with a very specific visual effect on D3D12. This effect is present in a lot of the game's stages, and as such is a relatively significant nuisance. The effect in question can be seen whenever Mario is travelling to a stage, and in quite a few stages in the background. See attached screenshots for example location, the first actual stage of the game.

This problem occurs any time the effect in question is on screen while using D3D12, and is easily reproduced. Interestingly, this does not happen when using OpenGL. The effect in question appears to be broken and does not show up at all in D3D11, circumventing the issue.

This is happening on 4.0-8947, I have not tested any other versions yet.

My computer is as follows:
Windows 10 x64
Intel i5-6600k @ 3.97 GHz
8 GB DDR4 memory
Nvidia GTX 970
