Hi Imagamer,
I believe your issue is that Plex does - not - like - Navi-GPUs (or the other way around) too much. But would you mind opening a new thread for that? The forum should not become too messy with several issues in one thread. You also ping all the people (including me) dealing with the OP issue, not yours. Not in a mean way, but - you know - keeps my inbox tidy.
