Hi, As it is now If I try to run any godot project in a computer/laptop without GPU it fail with error.

Is there a system to make a "virtual" GPU in order to be able to make games in low rating laptop- or force godot to use cpu to emulate gpu? I have another laptops with intel card only and wont use it to make games ( I don't mind if they are slow - also can be even better because I will be forced to optimize them)

Thank you

After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentally overwriting files of the same name in the SYSTEM32 directory.

Bolded part is important. You don't really want to install the .dll file system-wide.

And for Linux? I don't want to use that OS :)

Ah, typically linux users ask for this kind of advice on their respective distros community channels(and perhaps so should you) so I naturally assumed you were asking about windows.

First step would be to look at this page to see if some precompiled libraries might already exist for your distro: https://www.mesa3d.org/precompiled.html

And here: https://www.mesa3d.org/llvmpipe.html

The later link includes also build instructions if no precompiled library for your distro exists, do note however the chances are high that even if your distros name doesn't indicate it, most distros are derived from either debian or fedora so one of the precompiled ones might work for yours.

https://wiki.debian.org/Mesa I followed these instructions. the test - glxgears -info - went ok. But Godot still give me the same error. How this is possible? What I missed? Any idea? Thanks

ps.: I tried Godot ver 2.1.6 and it work.

if you run $ glxinfo | grep OpenGL in terminal whats the output? Paste here so we can see.

test@kalitosh:~/Desktop$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 965GM OpenGL version string: 2.1 Mesa 19.2.3 OpenGL shading language version string: 1.20 OpenGL extensions: OpenGL ES profile version string: OpenGL ES 2.0 Mesa 19.2.3 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16 OpenGL ES profile extensions: test@kalitosh:~/Desktop$

Well, it seems you installed the mesa driver for your integrated gpu and not the software renderer.

Try creating a custom login session, and make sure to have LIBGL_ALWAYS_SOFTWARE=1 in the sessions environment variables. This way you have a special login session just for working with godot using software rendering.

In theory anyways, its been about 10 years since I last used linux as my primary system, so I have to google most of this myself here.

this come from another laptop where godot work fine: (base) vale@kalileno:~$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL core profile version string: 4.2 (Core Profile) Mesa 19.2.3 OpenGL core profile shading language version string: 4.20 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 19.2.3 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.0 Mesa 19.2.3 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00 OpenGL ES profile extensions: (base) vale@kalileno:~$

If I understand what is missing is that thing called "core"?

That's working ! :)

Perfect!

Thank you :)

Sir, May I get more info about this Mesa discussion? I think I have this OpenGL issue as well. I'm using intel hd graphic 3000, my display says that it supports OpenGL 3.1 but when I use the play test button in godot this not support any OpenGL errors shows up. Later that I know that its a driver problem. Unfortunately, the intel hd graphic 3000 has never been updated since 2015. Therefore I'm looking for alternatives. Please.

If your GPU supports only up to 3.1, then you have no chance of running GLES3 with your current hardware. You'd have to switch to the GLES2 rendering backend instead.
