Vulkan

随着年度游戏开发者大会（GDC）在旧金山拉开帷幕，Khronos的Vulkan工作组今天发布了Vulkan 1.1.104，附带了几个值得注意的扩展。Vulkan 1.1.104是GDC 2019的大更新，而不是Vulkan 1.2，但是作为工作组每周/每两周发布的一部分，这是一个相当不错的更新。

Vulkan 1.1.97 已经发布，该版本主要新增了一些扩展程序，内容如下：

  •   VK_EXT_buffer_device_address - Provides a means to query a buffer device address value for a buffer. That value can then be used to access the buffer memory via PhysicalStorageBufferEXT in GLSL and SPV_EXT_physical_storage_buffer from SPIR-V.

  •   VK_EXT_memory_budget - This exposes the memory used and total memory budgeted for a memory heap. From there it can be estimated for how much total memory from each heap a process is using at a particular moment.
