I'm using a MacBook Pro 2016 (13 inch) with an RX 480 connected through Thunderbolt 3 to try to play Twilight Princess (Gamecube version) but I'm getting really low fps and simulation speed.
I can't seem to find what is the issue though, the GPU is more than enough (on 4x the fps start to drop, left it at 2x to give it plenty of headroom) and the CPU appears to be half loaded only (using 10w out of the 19w it uses when fully loaded), the activity monitor reports 90% CPU usage (Unix kind, 100% means one core load) and the CPU history doesn't show any specific core loaded to the max.
macOS might be spinning the thread around too fast to be shown but I don't think that's the issue since the activity monitor would report at least 100% CPU usage, I have also heard about the poor OpenGL drivers Apple uses, but graphics settings don't make a difference. Any ideas?
