Performance is significantly less than expected

English Hardware
1

I have attempted to solve this problem before here, and it definitely made some improvements, but since then, I have noticed far more problems and I am really getting sick of it. The noticeability of this varies widely depending on the exact scenario, but this is what I have noticed:

  • On games (like Prison Architect), people with similar hardware can get 40x the number of entities on the screen as I do with smooth fps.
  • top still shows well over 100% cpu usage on some applications that aren’t that intensive.
  • My screen times out way earlier than it should (5 minutes vs 2 hours) even when watching Youtube and Netflix in full screen.
  • irqtop -s delta shows an overall delta of 10,000 right now and up to 25,000 at times. I cross checked this with number another tumbleweed system which had 3,600. Almost all of mine are catagorized as local timer interrupts.
  • GPU ‘coil whine’ is really loud even with fairly low usage. It sounds a lot more like something is boiling than coil whine.

Overall, my very expensive system is performing a lot more like a mid-range laptop. And I built this system to be as far away from a laptop as possible so this kinda sucks lol.

There were some open questions in that previous thread - it’s still open, so I would suggest following up there rather than starting a new topic. :slight_smile:

@WarJT Unless you use something like switcherooctl to launch applications on the Nvidia gpu, it will be using the Intel CPU/iGPU…

For example on my Dual AMD GPU laptop (my Intel/Nvidia system is on other tasks at present);

So as you can see I can switch between the two GPU’s, on your system it would be the Intel and Nvidia devices.

Interestingly enough, switcherooctl list returns nothing for me.

5

Did you start and enable the switcherooctl service?

6

I have now :sweat_smile:.

I am still learning all of this stuff so I don’t really know what all of that did but here’s what I did

switcherooctl list

Device: 0
  Name:        NVIDIA Corporation AD104 [GeForce RTX 4070]
  Default:     yes
  Environment: __GLX_VENDOR_LIBRARY_NAME=nvidia __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only

Device: 1
  Name:        Intel Corporation Raptor Lake-S GT1 [UHD Graphics 770]
  Default:     no
  Environment: DRI_PRIME=pci-0000_00_02_0

inxi -Gz

switcherooctl inxi -Gz

From my limited knowledge, I don’t think switcherooctl inxi -Gz did anything? Also it looks like my NVIDIA GPU was already the default so I’m even more confused now :laughing:.

7

It would seem so, so try something out and see if you notice a difference you could also install nvtop and monitor the gpu.

8

nvtop shows GPU usage significantly higher than expected, but the correct graphics card is being used. Other than that, nothing is new to report.

9

@WarJT So performance has not improved for the issues indicated?

To me default should be using all intel, not a mixture… That’s what I see on all my hardware.
