CPU-bound?. That's rare as I said I didn't noticed any issue, tested loading multiple locations including Act 3 and runs as always. But I use a M1 and the issue seems to affect Pro and Max chips, which differs their CPU cores configuration.
I don't have time to look check it with Activity Monitor right now, but it certainly shouldn't be CPU bound on M1 Max when it runs just fine on Steam Deck.
And yeah, it does generally seam to run better when I first start up (well,
after dealing with the other problem, anyway) and then get worse as time goes on. Going through a loading screen into a smaller, indoor location will see everything running just fine until going out into the city again, as well.
