Turned into a gist due to high likelihood of deletion. Also edited down to not include irrelevant trolling as to be useful to someone else considering Depth Reprojection.

Yes I know SSR and Parallax Corrected Shadowmaps work, but the consequences of errors in those depth tests aren't as high.

Lack of Generality (oh the irony)

You yourself state that this is general purpose engine, how is a technique that will have trouble with:

• deformables (cloth, vegetation, skinned meshes, etc.)
