Any way to force the game to run with OpenGL 2.1? (Linux)

[skylineone044]

I have a crappy laptop(20042 Lenovo G560), with: an Intel Pentium P6100 (2) @ 1.999GHz, which has integrated graphics (Listed as Intel Core processor),
running Manjaro Linux with the default video-linux driver, which supports up to OpenGL 2.1 (The output of "glxinfo | grep -i "opengl version"" is "OpenGL version string: 2.1 Mesa 18.3.3")

0.16 worked just fine, but as mensioned in an FFF, the game has been moved to OpenGL 3.1 (If I remember correctly)
But I updated to 0.17.0.
Which means my crappy laptop can't run the game anymore, and gives an error: "Failed to create OpenGL context: Could not create GL context: GLXBadFBConfig"

Although when I tried the video-vesa driver, the screen got all messed up, but through the many graphycal glithes the game managed to launch (And while the vesa driver was active glxinfo said it had OpenGL 3.1) but it broke itself, so I had to switch back to video-linux.

Which leaves me here. Could the game be forced to run on OpenGL 2.1, or perhaps a "Potato computer compatibility mode" could me added.

I'd say : impossible you'll have to invest into either a discrete gpu - even crappy - that supports the right version of opengl, or stick to 0.16.X, but maybe the devs will have a more nuanced answer

I am sorry to say - OpenGL 3.3 is the potato computer compatibilty mode ... otherwise we would go with 4.4+
You have to stick to 0.16 :/

Vulkan when? /ducks

When there's time ... hopefully before 1.0

Oh, so there's actually a chance ?
I wasn't really serious, I didn't think there was hope for that except for *another* complete graphic engine rewrite !?

No, from what I've heard they've been keeping it in mind while they were writing the engine.

Well that's unfortunate. Guess I'll be waiting for Vulkan then. :[

Unfortunatelly, Vulkan is available only on HW that usually supports at least OpenGL 4.5

Well then I guess it's time for an upgrade.
Thanks anyway.
