[SOLVED] Stutter, laggy desktop performance

Hi all,

I've just finished a fresh arch install on my desktop, and I am getting what appears to be poor performance, or stuttering when using desktop applications. This is particularly bad when watching videos and has extended to my terminal (keys not showing when pressed until another key is pressed). Game performance doesn't seem to be affected (have only managed to test CS:GO but it runs well apart from screen tearing - an issue for another day).

I suspect this is due to hardware video acceleration. I have worked through https://wiki.archlinux.org/title/Hardwa … celeration but alas no luck.

Using nvidia's proprietary drivers and VDPAU for video acceleration.

neofetch:

OS: Arch Linux x86_64 
Host: X570 AORUS ELITE -CF 
Kernel: 5.13.7-arch1-1 
Uptime: 7 hours, 25 mins 
Packages: 696 (pacman) 
Shell: zsh 5.8 
Resolution: 1080x1920, 2560x1440 
DE: Budgie 10.5.3 
WM: Mutter(Budgie) 
Theme: Mojave-dark-green [GTK2/3] 
Icons: Cupertino-Monterey [GTK2/3] 
Terminal: kitty 
CPU: AMD Ryzen 5 5600X (12) @ 3.700GHz 
GPU: NVIDIA GeForce RTX 3090 
Memory: 2488MiB / 32046MiB 

vainfo:

vainfo: VA-API version: 1.12 (libva 2.12.0)
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA-API - 0.7.4
vainfo: Supported profile and entrypoints

      VAProfileMPEG4Simple            :	VAEntrypointVLD
      VAProfileMPEG4AdvancedSimple    :	VAEntrypointVLD
      <unknown profile>               :	VAEntrypointVLD
      VAProfileH264Main               :	VAEntrypointVLD
      VAProfileH264High               :	VAEntrypointVLD
      VAProfileVC1Simple              :	VAEntrypointVLD
      VAProfileVC1Main                :	VAEntrypointVLD
      VAProfileVC1Advanced            :	VAEntrypointVLD

Should <unknown profile> concern me?

grep -iE 'vdpau | dri driver' /var/log/Xorg.0.log:

[     5.895] (II) NVIDIA(0): [DRI2]   VDPAU driver: nvidia

Any help would be greatly appreciated!

https://wiki.archlinux.org/title/NVIDIA … de_setting - parameter AND early loading

Parameter added to rEFInd:

nvidia-drm.modeset=1

Modules added to /etc/mkinitcpio.conf

nvidia nvidia_modeset nvidia_uvm nvidia_drm

Re-ran mkinitcpio

mkinitcpio -P

Reboot and no more errors in /var/log/Xorg.0.log
