No problem, I'll get a RPi 3 in the mail soon and I'll hopefully manage to install and benchmark the latest VC4 stuff from Anholt too see if it's even worth your time. Seems Anholt's super busy trying to make the driver compliant enough for the foundation to consider using it as default, which is what we need really!
http://anholt.livejournal.comOn the hardware side, I'm quite disappointed with the RPi 3 which still is 40 nm (power hungry and hot, the 50% performance increase comes at a 100% power increase), still has a bus that is too slow and too little memory for 64-bit. The GPU speed has been bumped to 400MHz, but apparently you can bump the RPi 2 GPU to that too without issues.
I'm looking at other boards even if that means porting to OpenGL ES which I don't like...
What about Vulcan, to me it seems verbose and super abstract, maybe it's a big leap going from OpenGL 1.0 to Vulcan directly? Can you draw a simple triangle with Vulcan programmatically or is it the same buffers and stuff as ES?
Also, off topic, I'm hoping to be able to get the screen of my HTC Vive with GLFW in LWJGL 3.0, do you think that would work even if it's "undetected" by the desktop and in direct buffer mode?
