[Bf-committers] Minimal Blender specs - 5 year old systems & OS

Hi Alexander,

With minimal specs I mean this:

- The reference we test Blender for and ensure it keeps working.
  (startup settings, OpenGL defaults)

With average specs I mean:

- The reference we release and configure and design Blender for.
  (UI layouts, tool designs)

Of course you then can still use Blender on a 1.5 Ghz cpu with simple graphics. But users of older hardware should expect to fall behind in performance and usablity, or even need to accept that a future release might not work anymore.

All this assuming we don't have people to support such old systems, and that we might accept code and design in Blender that's not working (well) on old systems.

Tablets (Android, or other) are a special case here. That project is still WIP and with unclear outcome, especially how this will result in usable software. I'm extremely motivated to get tablets supported well, but not at the cost of limiting our software for 3D professionals working on film, animation or games.
