OpenCL AMD Incompatible GPU I recently installed an AMD graphics card in my machine (Radeon RX570 to be exact), which should be OpenCL 2.0 compatible according to AMD, but when I try to set my Cycles render device to OpenCL, I get the "no compatible GPUs found for path tracing" error. This is my first time using an AMD graphics card- are any additional drivers are required for OpenCL to work in Blender?

I am running Linux Mint 19.3. inxi -G returns:

  Device-1: AMD Ellesmere [Radeon RX 470/480/570/570X/580/580X]

GPU rendering with OpenCL requires the proprietary AMD drivers on Linux. This is documented in Blender's manual:


  AMD drivers are open source, except for the OpenCL support which is available as part of Pro drivers. Installing packages through your Linux distribution is usually best. AMD also provides graphics drivers for download on their website if you need the latest version.
