In particular I was thinking about a3xx hardware that most likely can't physically support ES 3.1, and also drivers that may not get it for a long while. On Mon, Nov 9, 2015 at 6:29 PM, Ilia Mirkin wrote: > On Mon, Nov 9, 2015 at 7:10 PM, Ian Romanick

[Mesa-dev] Potential spec change request for EXT_buffer_storage

2015-11-04 Thread Ryan Houdek
I'm hoping to potentially convince about lowering the minimum requirement of EXT_buffer_storage from ES 3.1 to ES 3.0. The only thing that causes it to require ES 3.1 is glMemoryBarrier, which shouldn't really be a hard requirement since the extension can be used without it. This is also a similar
