Nvidia's OpenGL driver maps gl(Named)BufferSubData with some requirements to a fast. This path has an extra memcpy but updates the buffer without orphaning or waiting for previous calls. It can be seen as a better model for "push constants" that can upload a whole UBO instead of 256 bytes. This path has some requirements established here: http://on-demand.gputechconf.com/gtc/2014/presentations/S4379-opengl-44-scene-rendering-techniques.pdf#page=24 Instead of using the stream buffer, this commits moves constant buffers uploads to calls of glNamedBufferSubData and from my testing it brings a performance improvement. This is disabled when the vendor is not Nvidia since it brings performance regressions. |
