Hi guys,

Apologies if this is in the wrong sub-forum, I didn't know which was best...

After a (very) long time out, I'm trying to get back into PC gaming. I've recently got an Asus TUF Dash F15 - 12th gen i7, RTX 3070, I've put another stick of DDR5 in so it's now got 32gb. I'm really impressed with it. However, I'm getting very low CPU usage during games (0-3%), and I don't think I'm getting an optimum FPS. In some games (e.g. assassin's creed odyssey) at 1080p I'm getting around 70 FPS (with drops to low teens in places, which obviously causes stutter). F1 22 I'm getting around 70 fps. Forza 5 seems to be ok and is >100 fps. Dropping the quality down to lower settings helps with FPS (however, CPU usage remains @ 0-3%), but I'm thinking this shouldn't be required and I shouldn't be having problems with games such as AC Odyssey with this spec. GPU is being 100% utilised, but CPU usage hovering around 0-3% during gaming doesn't seem right?

I've been doing quite a bit of searching on google and I'm starting to think this could be a Windows 11 22H2 issue? I've disabled core protection (memory integrity) and a few other windows features, in line with microsoft's own guidance on the problem. However, it doesn't seem to have improved things. I've also tried reinstalling the latest Nvidia drivers, also tried an older Nvidia driver, without luck. I found a suggestion that 22H2 is causing Windows to under-report CPU usage, but that suggests it's just a reporting issue and wouldn't explain the poor performance I'm getting.

I don't have the option to roll back as I've got a fresh install of 22H2 Windows 11 Pro. Does anyone have any ideas, or are my expectations too high?

Thanks in advance for any advice.

G.
