Post From: Copied shaded rectangle performance with OpenGL

I need transparency enabled for these drawings to be of use. The question is the difference in GPU usage on the primary chart (nearly 0), vs the GPU usage on the secondary chart where the drawings are copied to (nearly 100%). Are the drawings effectively being calculated/drawn twice when being copied between charts? This would explain the dramatic performance difference, as it looks like shader performance is not linear. Can I just throw more GPU at the OpenGL shading function (vertex shaders?)? Can the precision of the shaders be reduced to speed this up? (Not sure if this is even related) Is there a metric to look for in GPU selection that will optimize for Sierra's OpenGL shading? |
