The D3D9 rendering path of DC edition has a terrible problem of performance (not present with D3D11 path).
I'm speaking of big shading/illumination errors AND performance drop in some areas.....and crashes too.

See/Download this video please! Detroit LIMB clinic outdoor in D3D9:

Devs, you can't let the game stay in this state!
