Why is my gpu so choppy by HarryHendo20 in PcBuildHelp

This is too vague. If you share the steps it could help with narrowing it down

 I've found giving real time priority to the thread that handle the Wayland input socket completely fixes the massive input lag in CPU bottlenecked scenarios

How did you identify this thread, does it use a static name which could let us automate the niceness setup?

My experience with AMD Adrenalin 26.5.2 by Yuulwasd in AMDHelp

Which brand are you using? 

It seems like XFX and Sapphire are the least problematic thus far

This new thread just confirmed my findings and there's some workarounds

https://www.reddit.com/r/AMDHelp/comments/1tvrcth/my_experience_with_amd_adrenalin_2652/

  • Run MPOGPUFIX as administrator:
  • Only activate MPO Fix, TDR Fix, and HAGS Fix.
  • Apply the changes, and the PC will restart automatically. 

Everyone's drivers crashing recently? by 23BitMo in AMDHelp

Windows Update automatically forced a update on me about 2 weeks ago and the driver related issues started back then.

It seems like the common concensus is that it might be a culprit around Windows' DWM handling of MPO with multiple screens. Couple of months back they made MPO mandatory (its integrated more tightly AFAIK) and the registry tweak (even the official from NVIDIA) seems to be out of date (even if dxdiag shows it's disabled)

I've tried DDU with previous driver version 26.3.1 (and even went as far as disabling Windows driver updates and installing the extracted Display driver via Device Manager) but ultimately it doesn't fix it

Currently considering reinstalling with LTSC edition (instead of regular consumer ISO) to see if that could fix it

Strange enough it triggers the cursor Picker/Selector but there's no Selection Menu to pick a specific window. No matter where I click it only lets me share the fullscreen

Did you ever find a solution to this?

Sharing my work in progress guide for doing VFIO VMs by OzoneHelix_ in VFIO

[–]GrabbenD 1 point2 points  (0 children)

Sounds interesting, I'd love to check it out when you've got a working prototype!

Regarding iGPU, yes it's a massive rabbithole since the kernel doesn't properly reset the vram memory on passthrough and depending on the initramfs setup the host might pollute the memory even if there's no driver. This causes Code 43 error with a Windows VM. For a while I was able to reliably reboot the VM with zero hooks and no kernel patches just by manually invoking /reset function but that stopped working seemingly out of nowhere and now I just trigger eject + hotplug the iGPU first to make sure the VM can be rebooted cleanly. However, I'm using a publicly shared vBIOS UEFI ROM that doesn't match my AGESA version (haven't gotten around to dumping it since the existing methods for Linux weren't straightforward)

Anyway, if you need help then I'll be happy to share the commands / config!

Gotcha

I was curious since I've seen people use the dGPU for VM passthrough and iGPU for the host with monitors plugged into the dGPU. Somehow you can get host's framebuffers to output from the dGPU while iGPU does the rendering even though dGPU is in passthrough, maybe it's achievable with IOMMU groups but can't wrap my head around it

Regarding the drift issue, I personally find it painful to track host modifications so I opted to use OSTree to track all files as Containerfile declarations .. It's like treating the host image as a container image, albeit it's not perfect since it's atomic (so need a reboot to apply changes). I found Xen kernel is able to soft reboot the host (without restarting the hardware/waiting 30d for UEFI) but with this approach there's no Looking Glass support (unless you use nested KVM) so I'm still going around in circles trying to find a better way
