6th generation Intel Core processors have been redesigned to offer higher-fidelity visual output, higher-resolution video playback, and more seamless responsiveness for systems with lower power usage. Sample enhancements include a GPU that, coupled with the CPU's added computing muscle, provides up to 40 percent better graphics performance over prior Intel® Processor Graphics. The 6th generation Intel Core processors offer a number of all-new benefits over previous generations and provide significant boosts to overall computing horsepower and visual performance. Its multicore architecture improves performance and increases the number of instructions per clock cycle. Intel Skylake Processor GraphicsĦth generation Intel Core processors provide superior two- and three-dimensional graphics performance, reaching up to 1152 GFLOPS. When switching, the application animates the image as a visual indicator of the change. Pressing the spacebar cycles between the methods so you can compare the effects.

The current performance for each approach is displayed in a console window in milliseconds-per-frame and number of frames-per-second. These calls are compared to a non-synchronized performance. The calls are glReadPixels, glFlush, and glFinish. The example application demonstrates the effects of three different OpenGL calls that cause the CPU and GPU to synchronize. Monitor the progress of the GPU by accessing the data from the buffers with Sync Objects. Increase the initial number of pools if the oldest buffer submitted for GPU consumption is still in use. For vertex buffer objects access newly copied chunks of data with firstIndex (for glDrawArrays) or indices/baseVertex parameters (for glDrawElements/BaseVertex).

Use glFlush() with caution if you must synchronize between contexts use Sync Objects instead.If you need to use glReadPixels() do so in conjunction with Pixel Buffer Objects. Avoid glReadPixels() or glFinish(), which force synchronization between the CPU and GPU.The OpenGL Foundation’s website describes Sync Objects at, but here is a summary of ways to avoid this issue: Unfortunately this hurts overall performance because the CPU stalls until the GPU has completed its action. 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. A computer with a 6th generation Intel ® Core™ processor (code-named Skylake)Īvoid OpenGL Calls that Synchronize CPU and GPU.The following are required to build and run the example application:

OPENGL 4.3 C++ DELETE OBJECT ON KEY PRESS 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.
