[Solved] Mac Pro - Sapphire RX 570 - poor performance
Mods please move if there's a more appropriate area for Mac OS GPU issues.
I bought this RX 570 card off Amazon. It works in Mojave but the performance isn't great at all...
Heaven 1920x1080, ultra quality, extreme tessellation, 8xAA: 840
Notably, Heaven reports the GPU as Radeon RX 570 (256MB) x1 - system profiler reports as 4096MB
I'm thinking maybe there's a kext file i need to edit.
Everything is working like it's supposed to. Heaven score is comparable to other RX 570 scores with that settings in macOS. It's lower compared to Windows but that's not an issue with the card.
