It's 2021, still got the problem on retina displays

I previously created this topic: Latest patch on 8th October makes my mac very sluggish

Issue remains, but now i’m using an iMac 2020 with 5500XT, still the same problem, my GPU is hovering around 95 celsius when playing hearthstone, even heroes of the storm on ultra preset doesn’t make my gpu even close to 80 celsius. I’ve tried “low resolution mode”, it helped a bit, now my gpu temp are hovering around 85-90 celsius, but isn’t it too high for a such game, lol.
