Possible? Maybe.
Playable? Fuck no.
You're welcome to try though.
You will need to install Mesa alongside GZDoom.
https://github.com/pal1000/mesa-dist-win/releasesI recommend grabbing the "msvc" version.
If you're using a 64-bit system, select the x64 folder and drop the dll's into GZDoom's folder. Make sure to get the "osmesa.dll" from the "osmesa-gallium" folder and drop it into the same folder too.
If you are not using a 64-bit system, then select the x86 folder instead.
*IF* you manage to get this working, set "vid_scalemode 2" in the console for best performance. That sets the lowest possible resolution for the OpenGL rasterization, which since that is being done on the CPU, you will need pretty badly. Make sure also to turn off texture filtering, do not use texture upscaling, and disable any unnecessary post-process effects, as all of those will further slow down the rendering if they are enabled.
