Symptoms

Really strange graphical behavior with a halo of sorts emanating from the heads of enemies and friendly NPC's. They say a picture is worth a thousand words, so here's a 1 200 000 word report 😄

Reproduction

Start the game with DX12 enabled and play until you meet first NPC or enemy. Would've worked around it by just using DX11 instead but the game is unplayable due to ho-o-o-orrible stuttering while processing shader data

Start by reviewing steam-391220.log and the linked full system information report, then reproduce Rise of the Tomb Raider (Steam AppID 391220) with DX12 on Proton 5.13-6 and Proton Experimental. Compare it with DX11 and use the NPC/enemy halo and shader-stuttering steps to verify the issue; done means the reported DX12 graphical behavior is no longer reproducible.
