this game feels quite good, but I can't get a stable fps. my gpu is rx 570
My PC runs at 720p with a GPU core clock of 1500Mhz. Since VRG is adjusted based on this, the power is lack with rx 570.
Try lowering the resolution from setting> gaphics> screen. You can change the value with the mouse wheel.
It is also effective to turn off the display of shadows and reflections.
I'll try that!
