99% lets you run at stock clocks, but doesn't activate turbo...

I have a OnePlus6 , had the S9+, iPhoneX, Pixel 2 XL all in the last 6 months. I have the Note9 now. Agreed. Very solid phone with no issues yet. I've had it since 8/23 or so (pre-order). Some notes some might find useful from someone who's owned most recent flagships... s9+ - No stylus. Yep, I'm one of the weirdos that uses it on occasion. Screen had grainy blacks even after firmware update. No PIP as the device was 8.0. iPhoneX - Really didn't like Apple's notch implementation. Couldn't do without PIP like I get with Android 8.1. Pixel XL 2 - Screen colors were difficult to deal with. I also wanted to offload this before the oleo coating wore off on the screen. (google it) OP6 - Software still feels unfinished. Was missing a few quality of life things that the Samsung software has. Speed is unreal, though. Camera was also a bit of a compromise compared to the note9 or Pixel2xl. Also took a trippy trip to Huawei with the mate 10 pro. Software was subpar. Hardware seemed fine, though.

Set max processor % to 99% on battery in advanced power settings. This will persist between reboots and effectively disable turbo boost. Don't edit your registry for this. Bad idea.

Windows reinstall is very likely to be a waste of time if you're trying to fix true limiting on your hardware. Why not run a live Linux distro and run some stress testing? This will take 15 minutes, including the usb creation, and net you the same results without causing more work with the OS reinstall. The good news is that you've probably always been dealing with power limiting, but something else is impacting your performance. You didn't go looking under the hood before the performance impact. I'd really not focus on this. Check to make sure you didn't enable "whisper" mode in GeForce experience and you aren't running in any type of power save. You can also set your max cpu performance in power options to 99% to artificially disable the processor's turbo boost, if you think there's some other kind of power/temperature limit being imposed. You'll notice you're running pretty close to the stock clock on the CPU, which could give you headroom elsewhere. Or... there are 14 other factors that would need investigating.
