Almost forgot to mention that I love HWiNFO! And you were right. I got it back now - with the same GPU driver Version, but with the driver type "standard" instead of "DCH"
I had to DDU my GPU driver a few days back and after that GeforceExperience apparently installed this DCH driver. Then the GPU Power reading in HWINFO was gone.
As far as I understand, in the long term everyone is supposed to use the DCH driver. So maybe its worth looking into this? Either the reporting functionality in the DCH driver is gone or HWiNFO doesn't "find" it in the new driver?
Interestingly GPU-Z was able to read the GPU power with both drivers, I really wonder why that is.
If someone is interested in how to get the standard GPU driver back:
For those doing a fresh install of Microsoft's latest Windows 10 operating system (version 1809 October 2018 Update), you may encounter an issue with NVIDIA graphics drivers. Namely, a message may pop up when you install the graphics driver, telling you "The standard NVIDIA graphics driver is n...
Thanks for your feedback. So it looks like there's something different in the DCH driver and I will need to look into that.
If you even get back to DCH, I'd be interested to check a few things there...
That would be great. If you do so, I'd need you to scan the drive and search for a file called "nvml.dll". If you find it, please tell me it's location. But it's quite possible that this file doesn't exist in the DCH version and that's the reason of the lack of GPU Power [W].
After the driver upgrade:
C:\Windows\System32 (<-- appears)
C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_6d316144c2e15454 (<-- changes)
One interesting thing about the "C:\Windows\System32" location... it seems to appear there with the DCH driver installation, as it was not there with the standard driver.
I also find it under "C:\Windows.old\System32" - the backup Windows made before the last "big" update. And with the old windows I definitely never used the DCH driver.
Well, at which location does it have to be after all in order to work properly?
Note that GPU Temperature is missing in my screenshot because the GPU was "sleeping". I'm running on a laptop with Optimus, so the Nvidia GPU is not always active. After running an app on the GPU, then it wakes up and the temp is available. GPU Power still is not available.
