GRVK is the open-source project implementing AMD's Mantle API on Vulkan. Mantle was the precursor to the Vulkan industry standard and while it's no longer in use by AMD, there still are some games out there that allow making use of it.

GRVK allows for such Mantle games to run atop Vulkan not only for AMD drivers/GPUs but also with NVIDIA and Intel graphics too. The original Vulkan API is derived from and built off Mantle so GRVK is able to map rather nicely and has been making progress in recent months. This weekend marks the third tagged release for the project.

GRVK 0.3 is able to compile all 118 shaders of the Star Swarm tech demo albeit doesn't run the demo yet due to missing features. GRVK 0.3 has seen many AMDIL to SPIR-V compiler improvements, more functions being implemented, 32-bit fixes, a crash fix for the Intel ANV Vulkan driver, and other improvements.

More details on the changes with GRVK 0.3 can be found via GRVK on GitHub for letting Mantle live on in 2021.
