iMac 2017 - gpu not available

Hi I just bought my iMac 2017 with AMD Radeon Pro 580 GPU but AE use just CPU so I found this message in preferences: GPU Not available - incompatible device or CUDA driver. So my question is: iMac should be professional tool for working with photos and videos and should work with Adobe creative cloud. My question is why it is not true ond how to fix that. If your product work just with Nvida GPU please write that information - which is BTW very important for us, simply everywhere. Thanks a lot for reply.

    You are just not understanding the preferences panel. The message is that GPU acceleration using the NVIDIA card is not available for Ray-tracing because you have no NVIDIA card in your system. This is normal, expected and well documented. Ray-traced rendering is a deprecated feature which means it is no longer being developed. The Ray-traced rendering feature never worked as it should have and NVIDIA went a different direction with CUDA so Adobe dropped support and development in favor of the newer C4D rendering system.

    Motion blur is not accelerated by the GPU in CC 2017 so if that is all that is being used then what you are seeing is normal. After Effects does not work like a NLE and the frame based rendering it uses does not take full advantage of your system power. Performance is improving with each build but for now you have to live with the way AE renders. All compositing and motion graphics apps I have experience with take a while to render and seem slow to someone that is used to editing on a NLE.

    Also, in the future, please just drag your screenshots into the reply field on this forum. It saves a lot of time when we can see it in the post and it requires absolutely no dime. Just drag and drop from Finder or the Desktop to the forum and you are done. No resizing or fiddling necessary.

    You don't understand what CUDA is for and contrary to your statment Adobe is communicating this very clearly. You just need to look for it. CUDA is only required for Raytrace 3D, which is deprecated and will no longer be developed. For everything else OpenCL and OpenGL are used, which work just fine on your Mac. Everything beyond that is irrelevant.

    Thanks for reply but in my case it is not true. This is what can I see in preferences: https://gyazo.com/b0aadd6a819f6375a3e9cf0edebcc9a4 GPU option is unavailable to select And this is how AE works: https://gyazo.com/2b0bf8b99ba343d5a4062389e659dda4 as you can see AE use just CPU and GPU is on 0% of processor usage and this is from render process with just pixel motion blur effect and it working very slowly and during any another AE working is situation same: just CPU is working and GPU not.
