Nier Gestalt [BLUS30481]

Starting from "rpcs3-v0.0.6-8411-85b1152e_win64" Pull Request #6207
I'm experiencing a huge performance regression on Vulkan and OpenGL.

The problem also affects the latest release "rpcs3-v0.0.6-8442-6e89e4eb_win64".

Before, the game run at stable 38fps with Vulkan and a little bit less with OpenGL.
Now the game runs at 8fps with Vulkan and OpenGL, especially when there are a lot of things on the screen.
