GRVK

GRVK is a Mantle to Vulkan translation layer.

Mantle was originally developed by AMD and DICE starting in 2013, in an effort to produce a low-overhead graphics API as an alternative to DirectX 11 and OpenGL 4. Mantle was discontinued in 2015, with only a few games ever supporting it. Support was dropped from the AMD drivers in 2019, and it was never compatible with Nvidia cards. Despite this short life, it spawned a new generation of graphics API, including Metal, DirectX 12 and Vulkan.

This project is an attempt to revive Mantle and make it run everywhere.
