Hi guys, I'm just saying that I tested and managed to play LoL perfectly with my ryzentosh.
VGA: RX580 4gb Nitro
CPU: Ryzen 3 1200
Run with the same performance as Windows.
RadeonBoost.kext(to be confirmed).
RadeonBoost.kextdoes not work for Navi since the 10.15.5 patch and Apple completely locked it out with Big Sur. And it mostly improved performance for benchmarks like Geekbench, but not for actual games
