As of GRVK 0.5, the following Vulkan extensions are required on top of Vulkan 1.2:

• VK_EXT_custom_border_color
• VK_EXT_extended_dynamic_state
• VK_EXT_shader_demote_to_helper_invocation
• VK_KHR_dynamic_rendering
• VK_KHR_swapchain

On Linux, wine 6.21 or Proton 7.0 or newer are required.

RADV is the main supported driver. Use mesa 22.0 or newer.

AMDVLK might work but is untested, as my GPU is not supported anymore.

Adrenalin 21.11.3 or newer is required. BF4 works with minor glitches.

Mostly untested.

Nvidia GPUs are not currently supported (see #28). The lack of uniform buffers in Mantle would make it very slow on Nvidia GPUs, until Nvidia fixes their hardware.
