Here are some details from the OpenGL Profiler I managed to figure out some things (I just included the top 5 as all the other ones are not that interesting):

GL Function # of Calls Total Time (µsec) Avg Time (µsec) % GL Time % App Time

CGLFlushDrawable 1,265 4087917 3231.56 82.08 6.86

glDrawArrays 2,106 260195 123.55 5.22 0.44

glBegin 14,525 140308 9.66 2.82 0.24

glClear 1,265 139147 110.00 2.79 0.23

glDrawElements 3,398 121990 35.90 2.45 0.20

So, from this I can see that glDrawArrays is taking up 5% of OpenGL time. What is OpenGL time? Is that the time my process spends in the OpenGL library?

Is there any documentation about how to make this faster? Is this considered slow?

Kind regards,

Samuel
