Re: Update on OpenGL performance on Intel GPUs

 

Well Lorenzo,
 
this was always my argument when I've started to write the GAL ..
 
Today even the Raspberry Pi 2 for 30 Euro has a GPU for OpenGL (ES 2.0).
 
Greetings,
Torsten

Where I said CPU, I was meaning Laptop… I must proofread before I
click the “Send” button.

Nice, it’s good to know that the 300EUR cpu range runs
OpenGL nice for our needs. That means we’re not adding a huge
entry barrier with the OpenGL implementation.

Well, I got rich (more or less) and plundered the store for a 300 EUR
laptop for the office. CPU power is slightly better but the GPU is not
a 'classic' i915 but an HD one.
 
Performance on the opengl view is *waaaay* better; this time opengl is
better than xlib drawing.
 
(the reason is that in the HD GPUs shaders are run on the GPU, not in
the mesa library :D)
 
So I'd say that Intel's GPUs are now adequate, if you have at least an
HD one.
