This makes it possible to use different shader languages by compiling them to that bytecode format. The primary shader language used here is [GLSL](data/shaders/glsl) but thanks to an external contribution you'll also find [HLSL](data/shaders/hlsl) shader sources. +## A note on synchronization + +Synchronization in the master branch currently isn't optimal und uses ```vkDeviceQueueWaitIdle``` at the end of each frame. This is a heavy operation and is suboptimal in regards to having CPU and GPU operations run in parallel. I'm currently reworking this in the [this branch](https://github.com/SaschaWillems/Vulkan/tree/proper_sync_dynamic_cb). While still work-in-progress, if you're interested in a more proper way of synchronization in Vulkan, please take a look at that branch. + + ## Examples ### Basics
