I know the last gz versions to support ogl 1.1/2/3/4/5. But what were the first?

I'm having a hard time telling what version of opengl is in one of my retro boxes. For example techpowerup says a geforce 4 mx is opengl 1.5 but wikipedia says 1.3. Gpu-z says 1.5 too. Same when I use another machine. Gpu-z even thinks something truly ancient like a tnt2 is 1.5, I don't think that version even existed when the card came out. The reason I ask about this is I want to be sure that an old version of gzdoom is using a certain opengl version. Why? Because if I'm unsure about the video card version, but I use a gz version that only recognizes up to, say, ogl 1.3, then I can be 100% certain that 1.3 or less is being used.

GZDoom's use of features is dynamic, i.e. it checks the extensions. So there is no such thing as a GZDoom version that uses "up tp" a given GL version without ever using features that were not part of that version's core.
