When to transition from OpenGL to Vulkan With the availability of Vulkan there are now two open graphics APIs that target similar platforms. This brings up the questions which API to choose for new applications, or what to do with existing applications.

Just because Vulkan is newer, it doesn’t mean it is always better, nor that OpenGL became an inferior choice over night. Will the application benefit from Vulkan? In this section we will discuss 5 important scenarios to consider to help you decide if it makes sense to port from OpenGL to Vulkan. After all, if you do all this work, you do want to see a benefit from it! • Rendering rate not limited by other CPU work. Download Free Acog Ob Gyn Coding Manual 2011 Software Reviews there.

Vulkan’s design allows great reduction in CPU time spent in the driver, therefore check whether your application is actually driver-bound and not application-limited. The latter is often the case for code-bases that have traditional scene-graph traversal which mapped well to the original OpenGL state machine. • Balanced GPU/CPU usage ratio.

There are no fundamentally different GPU features in Vulkan versus OpenGL. As a consequence, if the GPU workload dominates the rendering time in your application, and is expected to stay that way (growing problem size with new hardware generations), Vulkan may not offer any speed-up to you.

Or differently phrased, do you have a good use-case for the additional CPU time gained with moving to Vulkan (or indirect effects such as potentially lower CPU power usage)? • Intolerance to missed frames or micro stuttering. If your application is sensitive to stuttering, then Vulkan’s explicit design could allow you to manage state and resources better than internal driver heuristics, by controlling explicitly when expensive operations happen during rendering of a scene.

• Application’s work load is partitioned well across multiple threads. Vulkan excels in creating work for the GPU spread over many CPU threads. If your application is targeting that, or already scaling well across CPU threads, and you have exhausted modern OpenGL techniques, then Vulkan can improve the situation. • Off-screen GPU compute and graphics work. Vulkan does not need to “display” anything.
