Would it be possible to backport Mesa graphics stacks within backports from Ubuntu to Mint

Well, I don't really know how to start this ask, but here it will be;

In some way, default Mesa graphics are a bit underpowered for Ivy Bridge CPUs and older hardware, requiring to scale down the resolution or disable lots of stuff to be able to run a game (not a recent title, but something that can run in any operating system, specially distros of Linux), and they can run really well on other distros

My idea would either bring kisak mesa, or backport Noble/Jammy/Resolute's backports of Mesa and other graphics stacks for

In the above screenshot, I am running Mesa 26.1.4 thanks to Kisak, and as far as I know, PopOS 22.04 brings Ubuntu 24.04's Mesa and Nvidia for extended driver support, so I wonder if it is hard or easy to bring Noble's backports for the current supported Mint releases (21.x, 22.x, and in the future, 23.x)

Thanks for reading

Ubuntu LTS (on which Mint is based) already has backports of the kernel and graphics stack.
About the kernel hwe must be selected manually (there may be incompatibilities with dkms modules that do not support newer versions): https://ubuntu.com/kernel/lifecycle
There is also continuous backporting of the graphics stack: of xorg, mesa etc.
LTS versions of NVIDIA drivers are also being backported. Older, unsupported versions are also included in the repository to allow you to use older video cards that are no longer supported by recent drivers. However, you need to be careful when choosing the driver, as you may encounter problems. Older drivers may also only support the initial kernel version and not the hardware versions.

Maintaining the kernel, graphics stack and graphics drivers is a huge job that the small mint team, already overloaded with much else, would not be able to do and it is better to let Ubuntu take care of it as it already does a lot in this regard.
Is also possible use PPA (as you did) to get newer versions faster, but be careful because it involves more risks than using drivers from the more tested and supported official repositories.
PPA use is best left to experienced users, who can downgrade the drivers from CLI if they encounter problems that prevent the graphics stack from starting upon the next reboot.

Thanks man for answering, yeah, it's lots of work for an already really small Mint team, and it's best to let Ubuntu team take care of it as they always did
