Dynamic shadows artifacts

GetScreenSpaceData has non trivial cost associated with it. Suggest that you replace it with a function, that would grab only normals from gbuffer(or at least double check, if unused parts of it are compiled out of ASM. I believe they are not.), as well as exposing constants on that lerp for control, but overall, that would be a feasible temporary workaround. There are other potential uses for surface normal during shadow filtering btw.

Shader compiler are really good for removing unused parts of code. GetScreenSpaceData is used pretty much everywhere without worrying which parts are not used. I can check the ASM to be sure. I don’t use source code version so I can’t add control for parameters.
