You can use backport for MESA (24.2.8)/Vulkan 1.2.289
Now I did it properly and test it. I saw a massive performance increase for game loading and a better performance with Vulkan. Unfortunately , Vulkan 1.3 is not officially available yet for Pi, only 1.2.289 is available .You can get it only with MESA 24.3 but it should be soon.
Here's what I did :
1- Create an empty file /etc/apt/sources.list.d/debian-12-backports.list and write this inside with a file editor
deb http://deb.debian.org/debian bookworm-backports main
You must change the folder restriction first
2 - update MESA
sudo apt install -t bookworm-backports mesa-va-drivers
3- Double check your installed packages with:
dpkg-query -W | grep '~bpo'
4 - Update Vulkan if needed
sudo apt install mesa-vulkan-drivers/bookworm-backports
Note : - Do a backup first
- I also recommend to update cmake sudo apt install cmake/bookworm-backports.
