Confirm PerPixel Lightning is fixed, but here's an interesting thing, enabling PPL brought Shader Compilation stuttering back, I've tested it on recent master build with D3D11 backend, and disabling it actually help to reduce this stuttering like on your DX12 build
The second thing is that generated ps.cache files are smaller with PPL disabled
tested on Metroid 2 & 3, cause the problem is most noticeable with them
