I’m getting consistent half refresh rate FPS on my DP connected screen on driver 580.82.07 in KDE wayland, apt package nvidia-driver-580-open. This is a lenovo thinkpad p1 gen4 RTX 3080 Laptop GPU. External monitor is a ThinkVision P24H-2L @75Hz75Hz
Kernel 6.14.0-29-generic #29-Ubuntu
> cat /etc/modprobe.d/nvidia.conf
options nvidia NVreg_PreserveVideoMemoryAllocations=1
options nvidia EnableResizableBar=1
options nvidia NVreg_EnableGpuFirmware=0
options nvidia NVreg_RegistryDwords=RmEnableAggressiveVblank=1
This problem occurs when instructing KDE to do all compositing on the igpu, if I instruct kDE to do compositing entirely on the dgpu then performance is good, but thermals are constantly high due to the graphics card constant high power draw.
Do let me know if there’s more information I should provide.
Edit: adding information about kde:
KDE: 6.3.4
KDE Framework: 6.12.0
Qt: 6.8.3
