That [email protected] bug was fixed in 20.1.1, I haven't heard of any problems with OpenCL on Linux using Navi using amdgpu-pro. There is an unofficial github repo for Navi ROCm support: https://github.com/smartbitcoin/MyROCm I don't think AMD will add official support. They're probably busy working on adding support for the Mi100.

OverWatch is around 12% faster using the 19.50 amdgpu-pro driver than Mesa with the ACO compiler but it compiles every startup for 5 minutes while Mesa with the ACO compiler only takes a few seconds to compile the shaders.

OpenCl driver failures is entirely AMD's fault just because they are focused to develop ROCm, OpenCL vs ROCm there is no absolute disadvantage other AMD keeps using dated OpenCL C api

Ahh i was wondering what happened. I remember playing around with games on Linux 10 years ago, and it was safe to say that everyone's drivers were terrible. Anything graphics related ran terribly. I know drivers have improved since then, but i wasn't sure where or how.
