  • [SOLVED] How do I make it so that Mesa (or whatever) exposes more of the available OpenGL functionality?
[SOLVED] How do I make it so that Mesa (or whatever) exposes more of the available OpenGL functionality?
s8as8a Apr 26, 2020
If I'm correct, some functionality is already implemented but not exposed due to not all of the functionality of that OpenGL version being implemented.

So, how would I expose such functionality?

I vaguely recall reading that an environment variable or something of the sort could be used to achieve this.

I'm trying to get OpenGL 4.4 and 4.5 features, since right now, I only have up to OpenGL 4.3 (according to glxinfo).

(My GPU does not support Vulkan, and I don't have the financial means to get a new GPU for another few years.)

Any input would be greatly appreciated!

This are probably the variables you're looking for:

MESA_GL_VERSION_OVERRIDE --> e.g "MESA_GL_VERSION_OVERRIDE=4.5"
MESA_GLSL_VERSION_OVERRIDE --> e.g "MESA_GL_VERSION_OVERRIDE=450"

That's what I wanted to know! Thanks!

P.S.
Technically, I think you meant MESA_GLSL_VERSION_OVERRIDE=450, but I got the point! :D

P.P.S.
I find your word choice funny here, given that x-wing is your name. ("These are not the droids you're looking for.") ;)
