download-jdk VS mesa

There are plenty of vendors providing builds of OpenJDK free to use in production including Oracle themselves. Oracle's build of OpenJDK that is free to use in production is found here: https://jdk.java.net.

Java can also be found in OpenJDK. Download your version, extract it (usually, the default directory is /usr/lib/jvm), and point the java program.

As someone else has mentioned, Oracle JDK still has limitations when used in commercial applications. However, there are lots of JDKs that are free to use for anything you want to do with it. jdk.java.net is where I used to get mine from. If you want an installer adoptium.net is also great (that's the JDK provided by the Eclipse foundation).

Java.com is the website for the product Java. Oracle owns java as mentioned in 1 so it makes sense they would have java-related things on their website. jdk.java.net is the domain for the Oracle OpenJDK

This, the oracle JDK from oracle.com.. Not the Oracle build of the JDK from http://jdk.java.net/ which has always been free.

https://jdk.java.net/ is probably the most standard as those are the build from openjdk itself. The eclipse temurn is a different Openjdk build by a different organization.

OpenJDK is an open-source project. The key word there is 'source'. OpenJDK does not provide binary distributions. Yes, there is one available from jdk.java.net but that is the Oracle OpenJDK JDK.

No problems, AMD Adrenalin it's a part of Windows AMD drivers, but on Linux you have not this soft, here is link: https://github.com/Mesa3D/mesa

Basically there's this one driver for all intel/amd gpus (https://gitlab.freedesktop.org/mesa/mesa) and NVIDIA decided to make their own barely working driver (full of bugs) and also try to make their own standards & protocols instead of using the ones intel/amd have already created

For the curious (I was), I believe this is the associated commit: https://github.com/Mesa3D/mesa/commit/f2e535e4fed5bdc13e11a4...

So you're running Mesa 23 by compiling the code at https://gitlab.freedesktop.org/mesa/mesa/ then?

no it uses amdgpu driver which is build into / part of the kernel (device drivers), and you can use 2 userspace graphics drivers, one being mesa the other one being amdvlk

Good luck, check out https://gitlab.freedesktop.org/mesa/mesa and https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm?h=v6.2-rc1 this is for Linux, but I don't believe that the size of that project, would be different for windows.
