But you have a Nvidia RTX 3070 Ti:
I had similar issues with video.
I think you have the wrong drivers for your 30XX GPU. You need nvidia-open-dkms.
I’ll just tell you what others have told me, and this actually fixed most of the issues for me on a RTX3080 M:
First, remove incorrect drivers:
sudo pacman -Rdd garuda-nvidia-config nvidia-dkms nvidia-settings nvidia-utils opencl-nvidia libxnvctrl lib32-nvidia-utils lib32-opencl-nvidia gwe python-py3nvml nvidia-prime`
then (without reboot)
sudo pacman -S nvidia-open-dkms egl-wayland lib32-nvidia-utils lib32-opencl-nvidia nvidia-settings opencl-nvidia nvidia-utils nvidia-prime`
and type yes for all dependencies
then reboot
Then install vulkan and dxvk
sudo pacman -S dxvk vulkan-icd-loader vulkan-tools lib32-vulkan-icd-loader
paru -S lib32-libdxvk-gplasync
Then update kwin
kwriteconfig5 --file kwinrc --group Compositing --key Backend OpenGL3
Please see the topic I marked as solution here: Sluggish system on i9-11900H and RTX3080M - #52 by astrodarius
It’s a long topic about similar graphics issues, I was dropping a lot of frames (70%) when simply playing 4k videos.
