These are called Sync Objects and are designed to synchronize the activity between the GPU and the application. OpenGL contains a variety of calls that force synchronization between the CPU and the GPU.
Opengl 4.3 not detected on phone code#
The sample code is written in C++ and is designed for Windows* 8.1 and Windows® 10 devices. While this article refers to graphical game development, the concepts apply to all applications that use OpenGL 4.3 and higher. It is accompanied by a C++ example application that shows the effect of some of these calls on rendering performance. This article covers several of those calls and describes ways to avoid using them. To get the highest level of performance from OpenGL* you want to avoid calls that force synchronization between the CPU and the GPU.
