Just as an FYI, there's a patch that just went into mutter yesterday that handles loading Gnome 48’s GDM in Wayland with EGL streams, which is your only option for Wayland using the 470 driver...

But eglinfo doesn't show any Wayland support through this driver once you actually get into Wayland. See: https://gitlab.gnome.org/GNOME/gtk/-/issues/4950#note_2375106

If anyone has any ideas on how to get that to work, it would be much appreciated, as otherwise acceleration using the Nvidia driver in Wayland is broken.

When Nvidia had released the driver 470 was starting to add wayland support having problems.

does it work on my kernel?
my kernel from neofetch Kernel: 6.14.0-arch1-1

@Omar2812-spec Yes, it should. Since you are using Arch I recommend you use the nvidia-470xx-dkms AUR package, you can apply this patch on top of the PKGBUILD. Also in a few days this patch will likely be incorporated to the package.

please patch 435 nvidia driver kernel 6.13 and 6.14
