[kwin] [Bug 452219] Low fps and high CPU usage on external monitor connected to NVIDIA when default GPU is Intel
https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #80 from qtm...@gmail.com --- With nvidia proprietary (not open) 555 driver, nvidia.NVreg_EnableGpuFirmware=0 kernel option and Kwin 6.0.4.1 with explicit-sync patch I have nornal frame rate on external monitor and very small CPU usage for kwin_wayland process. But now I afraid another bug with kernel panic https://forums.developer.nvidia.com/t/series-550-freezes-laptop/284772/161 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #79 from Lucas Lima --- Chiming in since I'm still very invested in this. I'm also using the Nvidia 555 driver, and I believe the issue mentieoned here: > On KDE6 (kwin 6.0.4.1), wayland session with AMD radeon 780m IGPU and > NVIDIA GeForce RTX 4060 Mobile DGPU and nvidia-open 555 driver on my external > monitor connected to nvidia HDMI port I have low fps equal to half of screen > refresh rate. Is caused by the usage of the new firmware. Kinda off topic, but to fix it add nvidia.NVreg_EnableGpuFirmware=0 to the boot command line options. Now back to the issue, since it was mentioned that it would be fixed in a future driver release, even with the new driver things have not improved. After adding the mentioned command line above, I'm back to the same performance from 550 when using a external monitor in the port attached to the Nvidia card. I'm currently using the kwin-explicit-sync package from Arch even: https://aur.archlinux.org/packages/kwin-explicit-sync, and also setting the OGL_DEDICATED_HW_STATE_PER_CONTEXT=ENABLE_ROBUST to /etc/environment, but that also does nothing. -- You are receiving this mail because: You are watching all bug changes.

I have laptop with igpu amd radeon 780m and dgpu nvidia geforce rtx 4060 mobile. Laptop monitor is connected to amd igpu and external monitor is connected to nvidia dgpu by its hdmi port. When the video plays, for example in mpv player on amd gpu and laptop monitor cpu utilization by kwin_wayland around 5-10% for one cpu core. When this video playes on amd gpu but external monitor with nvidia hdmi port cpu utilization by kwin_wayland rises to 40-70% for one cpu core.

https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #41 from petrk --- No changes with that variable. I noticed something interesting, checking power draw via nvidia-smi on X11 session running external screen I get power ramps to 20W+ while moving windows around, on Idle I get around 4W. Now on Wayland session I can't get Nvidia to bump above 5W. On idle it stays at 2W. Not does that it that Wayland session renders on IGP for all outputs by default?

Can confirm. Checking with hotspot with glxgears running on an external monitor, 70-80% of CPU cycles are spent in eglMakeCurrent in the NVidia driver when we stop using the NVidia context.

Pushed by zamundaaa into branch 'master'. backends/drm: add another multi gpu fallback With the dmabuf multi-gpu path, a buffer is imported to the secondary GPU and presented directly, but importing a buffer that's usable for scanout is not possible that way on most hardware. To prevent CPU copy from being needed in those cases, this commit introduces a fallback where the buffer is imported for rendering only, and then copied to a local buffer that's presented on the screen.

Plugging in an external display and fullscreening an application on it is what this MR helps." Well, for me it's the USB-C out == Thunderbolt == effectively DisplayPort-alternate where the dGPU lives its life.

https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #24 from Robin Tetour --- I am expiriencing this on AMD (i915 + amdgpu) as an eGPU. Display connected to it is running at half the refresh rate even though it is set to 60 in the settings. When I run glxgears and force the Vsync off it somehow get unlocked - the glxgears reports much higher fps, but the whole screen feels still like 30hz. The issue persists when using GNOME. So it is wayland only for me regardless of what compositor or DE I am using. So it most probably is something in the GBM backend right since GNOME and Plasma uses the same thing. -- You are receiving this mail because: You are watching all bug changes.
