WARNING!!! IRAY Issue, CPU 100% issue when rendering with anything newer than 417.71 Drivers 1080ti

Hello,

Not sure if this was already posted here but I wanted to share a really annoying issue I just ran into.

I recently updated my drivers from 417.71 to the latest 418.91 and immediately noticed an issue when viewing IRAY through viewport or doing normal render. CPU slammed to 100% and entire pc chugged and ran slow. These are scenes that I have ran in the past without issue. I'm running a 1080ti.

I uninstalled and reinstalled driver 418.91 (clean Install), same issue. Uninstalled and went back to 417.71, everything went back to normal. CPU usage at a minimum. I tried going up one revision newer, driver to 418.81. CPU issue back again up at 100%!

From what I can see anything newer than 417.71 screws Daz up on my system.

Anyone else running into this?
