https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #98 from Lucas Lima --- Providing an update: looks like the situation improved a bit with 6.2.1.1 While the performance still at around 50% of the external monitor refresh rate connected to the discrete GPU, when setting Variable Refresh Rate to Always, the performance improves quite a bit, up to 90% of the monitor refresh rate around (150 fps, in a 175hz monitor). Hopefully, when nvidia decides to make their fix this will improve even more. -- You are receiving this mail because: You are watching all bug changes.

First, start a game using nvidia renderer. Then, put your game screen ON INTEL-GRAPHICS-CARD-OUPUT-SCREEN. If lucky, you can notice the fps has increased to the value you set. Addition: My laptop is an Intel+NVIDIA optimus one using Arch+kde plasma+wayland. Nvidia drm is enabled. options nvidia_drm modeset=1 options nvidia_drm fbdev=1 options nvidia NVreg_EnableGpuFirmware=0 options nvidia NVreg_UsePageAttributeTable=1 I guess it is caused by nvidia drm. I have tried more than five times and gotten all good results. I hope it is helpful for community and someone can resolve this problem.

https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #88 from Lassi Väätämöinen --- I am only able to reach 50% framerate on external screens with my Intel/NVIDIA hybrid graphics laptop (Lenovo P15 Gen2). Sounds plausible that it might be at least partly an NVIDIA driver issue, since I had mismatch in the NVIDIA open kernel module version vs. the proprietary driver part (550.100 vs. 550.170). When I had those mismatched components, the FPS capped at 30FPS, regardless of what the screen refresh rate was: 60Hz, 100Hz, 144Hz - it was all the time 30FPS. Once the driver components were reinstalled to matching versions (550.100), the FPS behavior went back to the 50% thing. E.g. when setting refresh rates, it was 30FPS, 50FPS, 72FPS. -- You are receiving this mail because: You are watching all bug changes.

Switch the laptop to only use the dedicated NVIDIA GPU if you laptop allows it (mine does). In this case everything worked fine since both the internal screen and the external screen were directly running from the dedicated GPU. Of course that this eliminates any of the power saving advantages that the hybrid mode may have. 2. I was able to use the nvidia-smi command to ramp up the NVIDIA GPU clock speeds. If I ramp them up to the maximum the performance issues disappear. Of course that, once again, this will probably have an impact on power consumption. These are just workarounds. What we really need is a proper fix. I believe that (pat of) the problem is that the iGPU does all the rendering and composting by default. Therefore, the iGPU must also renders what is shown on the external screen but it must be copied from the iGPU frame buffer to the dGPU framebuffer. If the NVIDIA GPU is not properly managed, its clock speeds are just too slow and it is unable to receive all that data in a timely manner. -- 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.

Also while testufo is running, when i open application launcher fps drops to 72 fps. - Brave on xwayland gets ~65 fps on testufo.com and shaking mouse has no effect. - Brave on Wayland (--ozone-platform-hint=auto) gets ~76 fps on testufo.com but it drops to 72 fps when i shake the mouse. - glxgears gets 144 fps and it drops to ~141 fps when shaking the mouse. - When i activate "Show FPS" desktop effect, current fps is ~195 maximum fps is showing 143 and when i shake the mouse, current fps drops to ~160 fps The Plasma 6 and NVIDIA 550 updates are improved performance a lot, now I can daily driver wayland on both home and work laptop (at work i have 75 hz external monitor and it was getting ~37 fps which was not usable).

https://bugs.kde.org/show_bug.cgi?id=452219 --- Comment #66 from d_avery --- I'm still having issues. Latest Nvidia driver (550.54.14-5) KDE Plasma 6.0.2 Arch Linux 6.7.9-arch1-1 Wayland session AMD Ryzen 7 4800H + its iGPU running Kwin GTX 1660 Ti Laptop (Turing) Laptop screen connected to AMD iGPU and DisplayPort monitor running at 1080P 240Hz (connected to Nvidia GPU). Glxgears only runs at around 80 FPS. In attachments 167220 and 167221 you can see CPU load increasing and glxgears framerate dropping depending on which monitor it is being displayed on. Mouse cursor movement is also not 240 Hz, or at least there are issues with frame pacing depending on what is being done on the monitor, I haven't been able to narrow it down well. -- You are receiving this mail because: You are watching all bug changes.

I installed the nvidia 550 driver and I started experiencing lags on external display like this on the X server. Strong FPS drops began in Wayland. On the nouveau Wayland works well, on the X server the artifacts are saved as in the video. On built-in display X server and Wayland work fine on any driver. On external display it works fine only on Wayland and only on nouveau.

It's around 150fps on a 165Hz screen, it may be closer than where it was, but not on there yet. Nvidia 550.40.07 on 4060Ti.

However, if I add the module **after** I got into plasma with: sudo modprobe -a amdgpu I get video on both the external display and my laptop screen, and the framedrops are gone!

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.
