Sorry, I meant 4 threads active, not cores. I’m still waiting on ER to install (work wi-fi isn’t the best…) but I assume this will be the problem. Thank god it’s me overlooking something and not a fault with the deck!!

I kept telling myself to try changing Proton but never did…this has worked with Hi-Fi Rush but I am currently re-installing Elden Ring.

Also I was checking through every single setting I could think of and discovered that I had accidentally disabled SMT on the default profile in powertools, so there were only 4 cores active…I wonder if this has been the problem all along?

Will have to do some more testing when ER is re-installed.
