The goal is to +have a thin layer between the application and the vendor GL library +that saves the GL API call arguments in a buffer and then calls the +vendor implementation in a secondary thread, asynchronously. This +technique is known as "GL threaded optimization" in NVIDIA drivers and +has also been experimentally implemented in Mesa. The project aims to +implement this technique as a standalone library, independently of +underlying vendor implementation, and with very high efficiency. The +talk describes the overall approach, several specific takes taken to +reduce dispatch overhead, and notes a couple of missing features in +the OpenGL API that would make such approach more powerful. At +present, a work-in-progress implementation (iow: quick-hack-level) can +outperform NVIDIA's counterpart on Unigine Heaven. |
