PlayStation 2 games play quite well on the Xbox Series S

[Squid Surprise]

Unless you upscale the internal resolution a bunch. Or there's a graphical effect that doesn't work on GSDX so you have to use the software renderer (until recently, a good example would be the Thermal scope from RE4, but I *think* that one finally got fixed). And I know a few cases where you have to use the Interpreter to get past certain scenes, in which case even my 8700k gets about 2-3 FPS.

Granted, there aren't *that* many cases, but they do exist.

lol... not quite a "most use" case....
