Find attached a log with the Atom, representing weak hardware with only
ps_2_0 support. These (esp. lots of Intel GMA systems) are likely also the
ones which would not be able to run a real OpenGL version, so I see need
for alternative ps_2_0 (GLSL 1.2) shader programs. Either this (running
still reasonably fast via ANGLE (about 7-10fps vs. 2-3fps with MESA)), or
a MESA fallback, or system requirements should climb to "Hardware with
PixelShader 3 (DirectX10)/GLSL1.30 (OpenGL3.0) support".
Kind regards,
Georg
