It means that it has an important GL extension we use to avoid a lot of driver overhead to go faster. You'll probably still trip over a lot of driver bugs

What I mean compared to snapdragon. 
I am still doubtfull (due to thermal throttle etc) thought until I see video footage.

Devices with that extension support starts to appear since may

TMCThomas plz run this app https://play.google.com/store/apps/details?id=de.saschawillems.glescapsviewer&hl=en and upload score to be in database

Then again due to note 9 big heat pipe I am not so concerned about thermal throttling.

I've run the app and uploaded. Hopefully it will be some use.

Nice
Newest drivers so far (r12) They have also GL_EXT_external_buffer support. Any use for it by devs??

still having all the extensions required by the emulator, Mali GPU it's slow compared to Adreno.

Yes even Mali 2018 
Scored lower than Andreno540

Same problem that have all the phones. If we will play only option are the SD versions. Or some nvidia device.

There is no point for this extension for us. It is nice that they support it, but we don't need to share a buffer between different devices or processes. For uploading data, ARB_buffer_storage is very fine, there is no better way.

We still seem to hit some slow path within their driver. AFAIK they have a worker thread, and we need to care not to hit any synchronization call. I'll check it out once I'll get the next driver update on the S8-Exynos here. Let's hope they let us call glSync or glMapBufferRange without stalling the GPU....

Is Mali GPU That problematic ? 
I thought buffer storage would solve every thing.
