There are just a handful of games like Battlefield 4, Thief, and others that can make use of AMD's long-deprecated Mantle graphics API as the predecessor to modern graphics APIs like Vulkan and Direct3D 12. Mantle never was brought to Linux given the emphasis quickly turned to Vulkan within The Khronos Group, but now with the open-source "GRVK" project it's being mapped on top of Vulkan...
