Ah interesting. Yeah, I know there's a big discrepancy in visuals between medium and higher settings. I think this is due to Unreal 5 and all the new lighting/raytracing features that are toggled between those settings. I probably won't use UE5 for my next project since the minimum specs seem rather high and it's a bit unwieldy/untested.
Glad you had an interesting experience regardless, thanks for checking it out.
