Vulkan runs really slow on Kubuntu 20.04

I have a Kubuntu 20.04 installation on an external drive (and Windows 11 on my internal drive, and another drive which i use for storing data). Vulkan wasn't working, so i added the repo "ppa:oibaf/graphics-drivers" and then i installed the packages libvulkan1, mesa-vulkan-drivers and vulkan-utils. That made it work, but now when i run anything that uses Vulkan, it runs really slow compared to OpenGL and Vulkan on Windows. When i run sudo apt upgrade, it complains about missing firmware files.

EDIT: Here's the output of sudo lshw -C display

EDIT 2: Someone on Reddit told me that it was because it was using the radeon driver instead of the amdgpu driver, so i switched to it and now it works as it should!

Please do `cd ~/Downloads && git clone https://kernel.googlesource.com/pub/scm/linux/kernel/git/firmware/linux-firmware.git && sudo cp ~/Downloads/linux-firmware/amdgpu/* /lib/firmware/amdgpu && sudo update-initramfs -k all -u -v` in a terminal.

I just did that and rebooted, it's still the same.

Is `apt` complaining for missing firmware now?

`sudo update-initramfs -k all -u -v` will show missing firmware files.

It is, but it's complaining about less. https://imgur.com/a/cYTIfu9

The files are not available in the official Linux Firmware of Ubuntu... Are the official drivers installed `sudo ubuntu-drivers autoinstall`

I tried running that, it said "No drivers found for installation.".

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
