OpenGL vs Vulkan

This video demonstrates a performance comparison of OpenGL and Vulkan under almost identical conditions. The performance, measured in fps and CPU/GPU load, is testet and recorded against different antialiasing settings (2x-8x MSAA and FXAA). The performance indicators, shown in the top left corner of the realtime simulations, are slightly inferior than the measured and averaged values due to the recording software. The simulation shows an FFT generated ocean, an atmospheric skydome and a sun. The scene is generated with a deferred rendering engine an post processing bloom effect. The GUI overlay in the top left corner is blended on top of the scene image. MSAA is applied by means of a sample coverage mask during the deferred rendering process. FXAA is deployed between deferred rendering stage and post processing effects.
