Does LZDoom use the same opengl version as GZDoom?

No, it uses the renderer from GZDoom 3.3.

It's the old renderer with later additions plus D3D for software.

It targets OpenGL 2.1 primarily and the software renderer on DX9.

However, In a recent comment Frag did mention it also supports OpenGL 3.3 with broken drivers, but this is not the main target of LZDoom. LZDoom (Legacy ZDoom) targets lower end GPU hardware first and formost.

GZDoom minimally needs OpenGL 3.3 but ideally loves Vulkan or OpenGL 4.5.

@Dr.Frag thanks for this release, this is the build i am going to use for my Doom adventures from now on.

Short for Direct3D. Its part of the DirectX component base.

So im asking about what renderer LZDoom uses because i'm trying to get LZDoom hardware renderer work on an old windows XP machine I got the other day.

It currently:
~Works with ZDoom
~Works with Zandronum, software only
~GZDoom 32/64Bit isnt recognised as a windows application.

So does LZDoom work on old machines like that too?

BTW, its a HP Compaq DC5100

EDIT: The small form factor version of that machine.

If Zandronum works software only, you won't be able to use LZDoom with OpenGL as well.

Ok, but what about GZDoom not being a valid application? Is that just because it has some compatibility issue with Windows XP?

EDIT: Because I could just get a cheap old graphics card and be able to run opengl.

Scratch that I just remembered that I have an old NVidia Quadro 600 lying around.

EDIT: But GZDoom still doesnt work :?

No, GZDoom no longer works with XP, compatibility was dropped when I upgraded the compiler to Visual Studio 2019 which no longer features an XP toolset for compilation.

What is the last GZDoom version that is compatible with windows XP?

More importantly is LZDoom more up to date than that version?

1) The last 4.1 release
2) Yes and no. The renderer is a lot older but it has integrated a few more recent features.

For playing more updated mods then should I use LZDoom?

More importantly is there a list of commands in GZDoom that LZDoom is missing? I cant find any lists or reference on the ZDoom wiki...

LZDoom should definitely run on XP, also lowres scaling modes are still supported natively for OpenGL but you'd need to set texture filtering mode to none.
OpenGL 2.1 is not the main target of LZDoom, GL 2.1 is required and 4.5 recommended. The old renderer tends to run better (and not crash) on old hardware and the modern one runs better on modern hardware.
