PowerVR SGX 544 MP and OpenGL ES 3


#1

Are you guys offering OpenGL ES 3 support to your licensees on older hardware such as those SGX 544 MP?

Unfortunately, SGX GPUs are not capable of supporting the entire feature set of OpenGL ES 3.0. However, there were a number of extensions added to the SGX driver to expose as many of these features as possible, for example GL_EXT_draw_buffers for MRTs.

Series6 was the first GPU to support OpenGL ES 3.0 (it’s also capable of supporting OpenGL ES 3.1)

I see, could it do texture arrays through extension too?

The GL_EXT_draw_buffers extension merely provides additional binding points for framebuffer attachments. It does not add texture arrays.

I’ve had a skim through the extensions that are available on SGX, but can’t find one that does expose texture arrays.
