Awful framerate pop_os! 20.04

[Gerbagel]

Hello! 

As the title says, I'm getting awful FPS on my system in pop_os! 20.04. I get around 15 to 16 frames in Kingdom Hearts II FM. I know I should be able to run this, as I've been able to run it on Windows on this same machine.

My specs are:
GPU: AMD Radeon 570 Series
CPU: Intel Core i5-9600k
RAM: 16GB 2777 MHz DDR4

I'm quite new to Linux, and would appreciate things being explained to me like I'm 5.
