Since updating to Win 10 21H1 build 19043.1023, I've noticed that the GPU clock speed (in GPU Tweak II) and then in GPU Tweak III in the monitor was 90 / 100 MHz more than the maximum set at, and that the card was heating up faster / running hotter as the fans were faster than normal. I don't know what is going on, but thought I should post as perhaps this could be a serious issue. Image attached whilst running Train Sim World 2 - you can see the disparity. Note: Armory crate is up to date, but the UI does not work due to a broken MS Store with 'The parameter is incorrect' type messages that I cannot seem to fix, despite best efforts.

I've created some custom profiles to get the speed desired.
