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.

NOTE: binutils 2.34 has known issues and should be avoided.

mantle32.dll/mantle64.dll/mantleaxl32.dll/mantleaxl64.dll will be generated.
After dropping the DLLs in the game directory, GRVK will get loaded by the game at launch. By default, GRVK will create log files named grvk.log/grvk_axl.log in the same directory.
GRVK_LOG_LEVELcontrols the log level. Acceptable values aretrace,verbose,debug,info,warning,errorornone.GRVK_LOG_PATHcontrols the log file path. An empty string will disable logging to the file entirely.GRVK_AXL_LOG_PATHsimilar toGRVK_LOG_PATH, but for the extension library (mantleaxl).GRVK_DUMP_SHADERScontrols whether to dump shaders (IL input, IL disassembly, and SPIR-V output). Pass1to enable.
