Is there any way I can start OpenGL in software emulation mode, like DirectX where there is reference rendering option?

1Initializing OpenGL is VERY platform-specific. So tell us what OS you're using, and whether you're using any wrapper library, such as SDL. – Ben Voigt Sep 09 '11 at 16:55

What does that mode do? Render with CPU instead of GPU, or something else? Force CPU rendering at: http://superuser.com/questions/106056/force-software-based-opengl-rendering – Ciro Santilli Путлер Капут 六四事 Mar 22 '16 at 08:54

if you are trying to just test your existing software there are a bunch of tricks... like: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=148011
if you are writing software and have the ability to specify the render... then in windows:
from: http://www.opengl.org/resources/faq/technical/mswindows.htm
To force software rendering from your application, choose a pixel format that is not hardware accelerated. To do this, you can not use ChoosePixelFormat(), which always selects a hardware accelerated pixel format when one is available. Instead, use DescribePixelFormat() to iterate through the list of available pixel formats. Any format with the PFD_GENERIC_FORMAT attribute bit set will not be hardware accelerated.
for linux or mac... I would have to look through real books... let me know if you are on linux/Mac
