Not really answering your question directly but Desktop chips have had
2.1 support for the past 12+ years. IMO trying to support systems older
than that is going to be more trouble than its worth, llvmpipe is
unlikely to give you very good performance on a system that old.

Hi all,
I am currently building an application using VTK 8.1 which requires
OpenGL 2.1, or more recent,

Contemplating using a software renderer for cases where the system does
not support OpenGL 2.1.
As Mesa is already offered on linux, this is mostly a Windows question.
1.My question is: Is it reasonable to think that llvmpipe (or other
drivers) will grand me a much wider
array of supported system if I use that implementation over the original
Windows one?
It would mean that systems that have no support for OpenGL 2.1 would
benefit from using Mesa over
Windows’ OpenGL and that Mesa is usable on much older/weaker systems.
2.Another way to ask the question is: Is there a way of knowing which
specs a system is required to have
so it can support Mesa’s implementation of all of OpenGL 2.1? (is it
common that a system(high or low end)
will support all of Mesa’s equivalents of OpenGL 2.1 features).
Thank you for your support.
