    That's a misunderstanding on my part then. I assumed it needed the non-NGG path because NGG was broken. Glad to hear that this isn't the case. Though if Navi14 uses the same architecture and belongs to the same family, it still sounds surprising that the same code path that worked on Navi10 doesn't work there.

    By the way you guys did a really god job on Navi10, I'm a happy customer of the RX 5700XT.

      Yeah, you have to read between the lines a bit. Sometimes the GFX core in a family of GPUs is exactly the same between versions, but Navi12 and 14 had some GFX core changes relative to Navi10, and have different compiler targets (gfx1010, 1011, 1012). That usually means slightly different code paths as well.

      Thanks for the feedback; good to hear your 5700XT is working well for you.
