OpenGL Extension support

I’m trying to use this opengl extension GL_COMPRESSED_RED_RGTC1_EXT.

Do you know if it’s supported in PowerVR Rogue 8XE GE8430 (using GLES 3.2)?
If yes, do you have an example for how to use this extension?

thank you.


Welcome to PVR Developer Forum!

Would you mind share the DDK version for this device?
We’ll check and get back to you.


Thank you for the quick response.
it should be : IMG DDK 1.15.6133109 (ti-img-rogue-driver → dunfell )

After checking our internal documents for the support of this extension and also while confirming with our OGLES DDK team, we found that this extension is currently not supported. However, it’s part of the 23.3 release coming soon.
But, it will be made available only on certain cores - those that support this DX format in Hardware.
GE8430 does not support DX compression so it won’t be made available for these cores.

Hope this answers your question. Kindly let us know in case you have any other queries.

Best Regards,
