OK. Thanks Florian for pointing this out. I'll drop the request to remove TIMESTAMP queries, under the assumption that they may be necessary in the future.Kirill, please adjust your code to query for the number of bits in TIMESTAMP queries, and choose your implementation strategy based on that.-KenOn Wed, Jun 8, 2016 at 3:21 AM, Florian Bösch <email@example.com> wrote:It should also be noted that although timer queries are not part of OpenGL ES 2.0, 3.0, 3.1 or 3.2 core profiles, they are part of OpenGL 4.0, 4.1, 4.2, 4.3, 4.4, 4.5 and Vulkan 1.0, including TIMESTAMP and precision queries. It is to be expected that OpenGL ES 4.0 will include elapsed and timestamp queries in its core profile. It is also the case that TIMESTAMP queries are the only queries supported in Direct3D 12, and that elapsed queries are emulated on Direct3D via timestamps.
