--- Comment #79 from Lucas Lima <[email protected]> --- 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.
