Bad CPU usage

[Sidiano13]

Hey, 

Im using my Omen max 16 for weeks and I had a lot of issues with high CPU usage games. I have a Ryzen 9 AI HX 375 with 32go DDR5 paired with an RTX5080 laptop. But there are some games my pc have hard time running  : Warhammer 40K Darktide, REPO, Indiana jones, DeepRock Galactic... And its always an issue of high pc latency or low 1% fps. I monitored my threads with HWinfo and mainly the 2nd and the 3rd core are really used, going up to 207% of usage while all the other core sleep at 50% usage. In Darktide, even in the lowest quality, I cant manage to have under 45ms of pc latency. In REPO, I have 240fps with an 60 average 1% fps dropping to 37fps lowest i've seen (which is crazy). 

How can I manage to have a better threads usage so my CPU wont constantly bottleneck my GPU?

thx

Did you check if temps are normal, not near 90°C? 

Try these

1. Open the NVIDIA App → go to the Graphics tab → select Global → set Power management mode to “Prefer maximum performance” and set Shader cache size to “Unlimited”. Click on apply in last if available. 
2. Open services windows and disable "NVIDIA FrameView SDK Service". Set startup type to disabled.
3. Open device manager, Expand Sound, video and game controllers and disable NVIDIA High Definition Audio and NVIDIA Virtual Audio Device 
4. Restart and check performance. These are the known cause.

Hey,

I do not have any temperature limiting, my GPU never reached 80°c since I got it. And most of the time when those porblems appears, I still have 10 to 20% of GPU unused. 

I tried the 3 other tips you gave me, hope it gonna help.

thanks for your answer

[Mr_RadhaTech]

Try and test those settings I provided and report back with results. I check further if issue remains

Okay so I tested it for few days, it sadly did not help at all. The most revealing test is on Plague Take requiem : average 80 fps with no FG max settings 2.5k. If I stay still I have this amount of FPS (70-80fps) with 91% of GPU usage. If I start moving, FPS drops with massive stutters and freezes and GPU usage drop from 91% to 50% as voltage goes from 0.850V to 0.7V.

It feels like a pipeline probleme idk what to do. My CPU have a lot of power still avaible, none of my threads are saturated

I suggest you to try this windows optimization:

Turn off Frame Generation if you are using it. If your laptop has any third-party antivirus software installed, it could be the cause, as it may consume a significant amount of system resources.

Also, disable the screensaver, automatic wallpaper-changing features, and Wallpaper Engine if you are using them. Disable all overlays as well.

I am using no FG, I disabled all overlays, all antivirus, all wallpapers, all unecessary apps. Still have massive drops in games. What can I try next?
