Mesa 17.x.x on Win9x

[awkduck]

@WhiteArmpits There are some "OpenGL" environment variables you could try.

For a test, you could try "LIBGL_ALWAYS_SOFTWARE=TRUE".

You could check the OpenGL version supported by your GPU, then try "MESA_GL_VERSION_OVERRIDE=2.1". 2.1 could be set to whatever versions your GPU supports.

I know using the VBEMP Vesa driver, I've needed to set environmental variables for SDL1.2 video and audio output/rendering. Otherwise some SDL applications/games run poorly. This is more true if your audio driver doesn't support accelerated Directsound (some AC97 drivers). So maybe you can tweak OpenGL to play along.

You would open a Command Prompt, in the folder of the OpenGL application you are testing, and type something like:

Quote

SET MESA_GL_VERSION_OVERRIDE=2.1

Then from that same Command Prompt enter the command to initiate your OpenGL application (Minecraft).

Minecraft may also have environmental variables, that could be set. It might not be a bad idea to check that out; especially if there is something to set comparability with older OpenGL versions.

Thanks, i'll try later!

Update: my IBM ThinkPad T42 just stopped working, and therefore I cannot try that anymore, I will have to wait to get a new 98SE laptop in order to do that now.

I'm sorry to hear that. My T42 just stopped turning on one day. It always ran a little hotter, then I thought it should. I blamed the GPU. I still keep it around. Donated the memory to a T40 (post Win9x Intel GPU), I had to buy in a mixed Ebay lot.

I hope you find something good.

Thanks awkduck, I hope I will find a T41p or T42p someday, those two are the ideal 98SE ThinkPads for me, I will let you know if that day will ever arrive
