State of OpenGL driver on Pi3?

Thu Jul 07, 2016 1:08 pm

I was going to get a Pi 3 B, partially for the extra power, and also because of the new experimental OpenGL driver (no, I don't want to play Minecraft on it), but after seeing viewtopic.php?f=66&t=150420, I'm having doubts... advice?

What do you want to do? Difficult to recommend without that sort of information.

Note the new OGL drivers works on Pi2 and Pi3 versions, not sure about Pi1.

I was just wondering how well it works in general compared to Pi2, seeing as some people in that thread seem to be having some problems with it, admittedly mostly on a newer kernel version...

Also, just so you know, the option for enabling the driver in raspi-config is disabled on Pi1.

People have problems because it's still in beta. There are still bugs.

Only OpenGL performance Pi2 vs Pi3 is probably negligible.
There are 10 types of people: those who understand binary and those who don't.

OK, to all intents and purposes, there is no difference between Pi2 and Pi3 with regard to this driver. The VC4 GPU core is the same (also same on Pi1, but I think it doesn't have enough memory)

The fact that opengl support is in alpha and just gives people black screens when trying to boot with the latest version of raspbian os pixel is kind of a big deal. I'm trying to code a program and i'm getting 3 frames per second and 99% cpu usuage just by drawing a quad. Its kind of ridiculous, the hardware is more than capable of supporting it. The chip natively supports open gl es.

Not quite sure what you are getting at. The driver is indeed in its early stages, so issues are to be expected.

The standard OpenGLES library API's are available (and have been for 4 years) and work fine - you should be getting up to 60fps on complex scenes using that - all the demo code works that fast. What they don't do is interface particularly well with the X window system, so no windowing.

Is there some documentation, demos, anything at all that I can find on this?

I've been searching for some days and I still can't get any sort of GPU support working on my pi2.
My goal is to use Qt5. It can use a framebuffer just fine, Qt supports wayland and X11. So it should really work, but it doesn't... (using raspbian)
