System.NullReferenceException: OpenRA.Graphics.Renderer

[Vassonx]

So I just recently installed OpenRA playtest- 20131112.

I just click on the icon to start the thing up and after a little while, expecting OpenRA to start up but all I get is crashing and Windows asking me to send an Error Report.
I use Windows XP SP3.

This is the entire contents of the exception.log (There wasn't anything else):

Hope you can fix. Good luck :)))

Can you try http://open-ra.org/news/playtest-20131130?

[Vassonx]

huh? I can't seem to find a link to download the 20131130.

[Mailaender]

http://openra.res0l.net/download/ My Chromium always needs me to hammer F5.

[Vassonx]

Still crashing.

Have you installed the manufacturer-provided drivers for your graphics card? (this is mentioned on the download page).

[Mailaender]

I wonder why we get an NRE here. It is pretty much impossible to break the renderer since #4038 even when I explicitly set Graphics.Renderer: to an empty string. Is the graphics.log really empty?

[Vassonx]

Here is the Graphics.log

[Vassonx]

Intel(R) says my driver is up-to-date compared to my graphics card. So i suppose my graphic card might be crap or I don't know another problem. Strange through, It can handle other old games just fine.

[Vassonx]

Either my software is shit or my driver seems up-to-date.

Unsupported GPU: Missing extensions: GL_ARB_vertex_shader,GL_ARB_fragment_shader,GL_EXT_framebuffer_object

GMA 900 is far too weak and does not even have the required OpenGL extensions. https://github.com/OpenRA/OpenRA/wiki/FAQ#no-valid-techniques-or-unsupported-gpu

It is strange however that it dumps a NRE into exception.log and the actually readable exception into graphics.log

System.InvalidOperationException: OpenGL Error: See graphics.log for details.

This could be a side effect of #4038. I think we want a specialized error pop-up for this common error: no driver please update if Vendor.Contains("Microsoft") and too weak hardware if Unsupported GPU: Missing extensions (this case)

[Mailaender]

Fixed with #4326
