Dota 2 is now Vulkan API ready. The beta version is available via DLC. This is a blog post on how to setup Dota 2 with Vulkan API Support. This post will help you to enable the Vulkan API Support for Dota 2.
What is Vulkan?
Vulkan is a new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in a wide variety of devices from PCs and consoles to mobile phones and embedded platforms. To know more, go to https://www.khronos.org/vulkan/
Minimum Requirements for Running Vulkan :
- Windows 7/8/10 64-bit: NVIDIA 600-series+ (365.19+ driver), AMD 7700+ (Crimson 188.8.131.52+ driver)
- Linux 64-bit: NVIDIA 600-series+ (364.16+ driver), AMD GCN 1.2 (16.20.3 driver)
- 2GB of GPU memory required – may experience crashes with < 2GB of GPU memory.
- Please make sure to opt-in to the Steam Client Beta for the latest Steam Vulkan Overlay (fixes performance issue with Steam Overlay)
- Remove -dx9/-dx11/-gl (if present) from any previous launch options.
- Make sure your graphics drivers are updates.
- The first time you run with Vulkan you may experience short stutters while the engine caches shaders on disk. After playing through or watching a match, these stutters should go away.
- There is a known issue on Linux with NVIDIA GPUs where tearing can be observed even when vertical sync is enabled. NVIDIA is aware of the issue and it will be fixed in the future through a driver update.
- Please file any bugs with the Vulkan version at https://github.com/ValveSoftware/Dota-2-Vulkan/issues/
