Hello Arch Friends,
Perhaps i have relatively speaking high expectations of Wayland in it's current form but is it possible to get Hardware Acceleration with Nvidia to work on Wayland? Because I had no success in it so far.
My GPU is a GTX 1080 Ti and it falls under the proprietary nvidia drivers for either "nvidia" or "nvidia-dkms" package. I am using nvidia-dkms here.
My current Linux kernel version and nvidia driver version are linux (non-lts) 6.13.2.arch1-1 and nvidia-dkms 570.86.16-2
but i have also tried to get it to work *before* performing pacman -Syu with no difference either using nvidia-dkms 560 with it's respective kernel version linux-6.11.9.arch1-1. I mention *before* because this is relevant to what's changed.
I tried some things.
installing nvidia-vulkan from AUR using yay:

driverUUID = 4a385d89-2a0a-49d7-f263-43c1e5335f32To me it looks like a vulkan <---> nvidia (dkms?) driver problem. More so I don't see my GTX 1080 Ti listed here anymore (i saw it when i had the linux kernel version matching the nvidia driver version 565).
What's weird is that ffmpeg CAN encode & decode video files using nvenc and nvdec (using the Nvidia GPU to perform video conversions from or to H265 codec). OBS Studio was able to encode video captures using nvenc H265 but since i performed pacman -Syu this encoding option has been lost.
I have not yet tested this using the normal X11 display thingy.
I have heard several things such as nvidia proprietary drivers having terrible support for linux (that or wayland having issues with that) or that driver version 570 broke HW acceleration ( from https://bbs.archlinux.org/viewtopic.php?id=303202 )
What can I do? Should i start using the normal and what I think is a less flexible "nvidia" package over the DKMS variant?
Update:
Just booted up on my LTS kernel linux-lts 6.12.13-1 and nvidia-dkms 570.86.16-2 (as it is displayed from pacman -Q). Vulkaninfo now correctly lists my discrete 1080 Ti. Plus mpv shows less errors but one remains.

Exiting... (End of file)So it looks like HW acceleration works on the LTS kernel since I see the Using hardware decoding text but I'm not sure if i must worry about vaapi because it's text is in red color and it looks like a nvidia driver initialization has failed.
Also something got screwed up since I performed pacman -Syu for Linux kernel 6.13 - specifically it boots up with a kernel panic: not syncing: No working init found (missing init= option to kernel). That's a separate issue with the kernel however.
Update 2:
Just regarding the kernel panic error, i actually ran out of space for my encrypted boot partition mounted under /boot having only 512 Megabytes *facepalm*

As from my updates to my original post, i seem to have magically solved it myself and the worst part is i don't even know what I did except rebooting the system after running pacman -Syu, which got my nvidia-dkms driver version to 570 and linux non-lts kernel to 6.13 - it so happened, that mkinitcpio during the pacman -Syu operation was unsuccessful because my /boot partition ran out of space.
In the meantime i doubled my /boot partition size and mkinitcpio worked through.
While I don't see HW acceleration being available to Firefox, at least on Steam it works. And MPV reports successfully too.
