How to run software renderer?

[omxgamer127]

Hi it is possible to choose between software mode or opengl or vulkan by a command line?
I need it because i'm using a doom launcher to run my collection of wads ,when i click on start to play it's not ask me because all iwads are already configured to the specific pwads
The port the most i use is LZDoom_3.88b
Give me all the commands if it's exist

@lafoxxx i have this error : Unsupported OpenGL version.
At least OpenGL 3.3 is required to run GZDoom.
can i use mesa to bypass it? i'm on windows i found a windows version here : https://github.com/pal1000/mesa-dist-win and here : https://fdossena.com/?p=mesa/index.frag
In the official wesite : "Mesa releases are available in two formats: .tar.xz and .tar.gz."

Use the "softpoly" backend when starting GZDoom.

If you're using the command line you can type "+vid_preferbackend 2" when starting GZDoom. You can try 3 instead of 2 just to test.

Either way though your GPU is much too old to run GZDoom.

Also - please don't bump really old topics. I will split this one into a new topic.

Looks like a problem with GPU driver. OpenGL 3.3 is quite old tech.
What is your GPU?

I found a solution here : https://community.citra-emu.org/t/force ... dows/14122

You can force that all your want but a HD3000 only has supports for OpenGL 3.1. Anything above and you are just running into weird fixes that aren't really fixes at all.

Frank of the matter, a HD3000 is just really old and it just does not cut it for GZDoom at minimal settings. Stick to other ZDoom flavors or use the GLES renderer.

Somehow i missed this thread, he wrote me a PM on Discord and he managed to get the Mesa driver running but of course it's a software driver.
I advised him to use softpoly too.
