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 update && sudo apt upgrade 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.

You could rename the mesa_shader_cache first before you remove it.
Then you can always remove it later if you find that there are no problems.
Good idea ?

Yep. Very good idea. I'll rename it to see if there is any issues and if there are I'll just rename it back.

@gleam2003 said in Lock SDL2, MESA and DRM update:

Install your Mesa and sdl2 library in /usr/local and config LD for use this before the one installed by RetroPie.
In this way you can use original RetroPie script without lose your build library

Thanks, I'll try
