Describe the Bug

Characters have a shadow over them when using HW renderer. This issue was previously mentioned here #12172 , in the last message. The reporter had an NVIDIA gpu, and he managed to fix the shadows using Half Pixel Offset. I have set the Half Pixel Offset fix to all possible values and it did not fix the issue for me

Reproduction Steps

  1. Have a non-Nvidia GPU???
  2. Set the renderer to DirectX with any Blending Accuracy, or OpenGL/Vulkan with Blending Accuracy lower than High.
  3. Start a new game and watch the first in-game cutscene.

Expected Behavior

This game should have the half-pixel offset preconfigured to Special (Texture) and (not sure about this one) for AMD iGPUs the blending accuracy should be set to High.
Screenshots from Vulkan with High Blending accuracy:

I don't see what HPO Special does for the dump and as for blending I'll change what we already do which is recommend high blend to a minimum of high blend as it's needed for it to work correctly in OpenGL Vulkan and Metal.
