Marvel's Guardians of the Galaxy - perhaps unexpectedly - is one of the best games of the year... and now it's even better. In addition to quality and performance modes, PlayStation 5 and Xbox Series X also benefit from a new ray tracing mode. So what does it do, how does it change other elements of the game, and how does it rate against the PC version's more fully featured RT settings? Oh, and since Guardians of the Galaxy has been patched, what's the score with the somewhat lacklustre Xbox Series S version... has it improved?
