Higher than normal CPU usage on desktop/idle on Intel 12th Gen + RDNA3 platform
RodroG-85 opened this issue · 24 comments
Hello. I noticed again that the CapFrameX process shows higher than expected CPU utilization (constant CPU usage fluctuations, about 1% to 2%) on desktop/idle conditions with Overlay enabled using v1.7.1 and the latest pre-release beta build.
While in-game and capturing, the CX CPU % sensor shows continuous fluctuations from 0.0% to 0.3% max. This one seems a more expected percentage, though.
I had to roll back to version 1.6.8 to see a steady 0% CPU usage of CapFrameX.exe on desktop/idle/minimized-to-system-tray conditions with overlay features enabled. However, this version lacks many recent and new features, including Win 11 (coming from PresentMon v1.8.0 and later versions) and RDN3 support.
My system/platform specs are attached below:

Please, could you look into this?
Best regards.
I can confirm the behavior, see here: GPUOpen-LibrariesAndSDKs/ADLX#11
You can try to use the "ADL Fallback". At the end, it's up to AMD to fix this.
Thank you. I will try it. Hopefully, AMD will take the report into account at some point.
I've just seen that ADLX SDK was updated recently to v.1.1, but I don't know if this changes something regarding the issue.
https://github.com/GPUOpen-LibrariesAndSDKs/ADLX/releases/tag/v1.1
I've already updated the latest ADLX version.
Hello, just to add some salt : I've the same issue on two computers : Ryzen 9 5900X + 6700 XT and Ryzen 5 5600X + 6700 XT. Tried the ADL fallback but no improvement.
Got some tips from an AMD dev(?!). I've changed the ADLX API calls. Please check the following version (Build 110):

Thank you! I will check it and will report back.
It seems better with the 110 version on the 5900X, I'll check also on the 5600X.
@DevTechProfile CX CPU utilization on idle/desktop conditions is slightly better using build 110, but the issue persists. Using 110 ver, the app's CPU usage continuously fluctuates from 0.2 to 0.8% on idle/desktop, and on the same conditions with "ADL Fallback" enabled, the CX CPU usage now spikes from 0% to 0.1% all the time.
AMD should further mitigate CPU usage for their ADLX API calls.
Working on it. This has nothing to do with the AMD library.
Edit... it has something to do with the ADLX... ^^

What a pity @DevTechProfile
So, can you do something to resolve or further mitigate the issue?
Looks like I've already fix it. Will upload a new version asap.
New problem, TBP is not being detected any longer. This AMD stuff kills me...
I'd some strange behaviour with some beta drivers from AMD (the FSR 3.0 related), I was missing some informations about the card like RPM Fan and so on. The 23.11.1 seems to be OK now. Can it be related to your problem ?

@DevTechProfile how is it going?

I tried a lot of variants but at the end I came to the conclusion that the ADLX causes a significant CPU overhead, no matter what API calls I am using. It's up to AMD to fix that.

I hope the AMD guys do something and don't ignore the issue or take years to fix this CPU overhead.
Given the current situation, you could add a warning informing the users about the issue.
