How can I run OpenGL3.2 application on GL2.0 device #57

Closed xtexChooser closed 3 years ago

xtexChooser commented 3 years ago

Mesa3d looks like supported rendering by software, so I want to run Minecraft on OpenGL2.0 computer. Minecraft is required OpenGL 3.2 in the latest snapshot version. I setted the environment variables: MESA_GL_VERSION_OVERRIDE: 4.6COMPAT MESA_GLSL_VERSION_OVERRIDE: 460 LIBGL_ALWAYS_SOFTWARE: true But the game tell me:

A forward compatible OpenGL context requested but WGL_ARB_compatibility is unavailable

The AIDA64 tell me: The ICD is mesadrv but OpenGL version is 2.1.0 The max viewport size is 4096*4096 and GL_ARB_compatibility is not supported. My graphic card is only supported OpenGL 2.0 I am using Windows7 32-bits

Try with

MESA_GL_VERSION_OVERRIDE: 3.3
MESA_GLSL_VERSION_OVERRIDE: 330

and drop LIBGL_ALWAYS_SOFTWARE: true. That only applies to GLonD3D12 which I doubt it can run properly on Win7.

I installed Mesa3d to the Java Runtime. I installed it to the system before.

I might sound Stoopid saying this but is this for windows or Linux and where do I put the Mesa override variables...

Windows.

and where do I put the Mesa override variables

You write a filename .cmd file that in addition to setting Mesa3D environment variables, it also starts your program of choice. Alternatively you can set Mesa3D environment variables in Edit environment variables for your account in Start search.

thx for the tip but can you help me wirte a .cmd script?? I want to run Minecraft Launcher with mesa env variables...

For something like Minecraft you probably don't need to set OpenGL context control environment variables anymore. llvmpipe support OpenGL 4.5 on all contexts. So just deploying should be enough.
