>>>the VideoCore VI GPU can do OpenGL ES 3.2, but it can’t do OpenGL 3.0,
> Can you give a bit more details on this issue?
It is an issue with HW limits. Videocore VI hw only supports up to 4 multiple render targets.
For OpenGL ES that is enough, as the minimum value for GL_MAX_DRAW_BUFFERS is 4 (see table 6.27 on OpenGL ES 3.0 spec).
But for OpenGL 3.0 that is not enough, as the minimum value for GL_MAX_DRAW_BUFFERS is 8 (see table 6.51 on OpenGL 3.0 spec).

Wait, what? I always thought the GPU supported OpenGL 4.x. It's kinda weird to me that it doesn't support it but supports Vulkan (not saying that supporting Vulkan is bad thing of course). I'm just genuinely surprised.Zink on V3DV allows for OpenGL 2.1 support to be exposed, which is the maximum desktop OpenGL version supported by the Raspberry Pi hardwareLeave a comment:

Michael please stop chanting every other day about Zink. It is an extremely inefficient solution and I will risk, an uneducated, analysis this problem has a fundamental basis. It is based on the architecture of Gallium. For this reason I predict that a performance similar to the DXVK will never reach. It's a good experiment but let's not go over it.Leave a comment:
