One thing you should to know is that: VIM3 GPU doesn’t support OpenGL.
It supports OpenGL ES 3.2, Vulkan 1.0 and OpenCL 2.0, you can check the datasheet.
There are some GPU demos in the image you can run under framebuffer. /usr/share/arm/opengles_20.
The FPS for these demos should be 60FPS.
If you want to run OpenGL apps on VIM3, maybe this will help you:
Sorry, I’ve corrected my link.
And yes, my question is for OpenGL ES.
I’ve checked the test binary at /usr/share/arm/opengles_20. that’s working correctly.
It was not a issue.
