Any advancement on this?
With another Nvidia user ( Pascal GTX 1060 desktop) we are able to reproduce the issue.
To put it simply ; on Optimus setups app profiles doesn’t seem to be applying.On a desktop system (or any other unaffected system) modifying binary driver as to look for randombinary.exe instead of DOOMx64vk.exe will reproduce the issue. This behaviour also explains why issue below happens too. Same issue.
