The Callisto Protocol was not perfect but it was a pretty effective survival horror game that was just a little too short and somehow frustrating because of its combat system against multiple enemies. That said, the game looked really good, especially in Fidelity mode with the Ray Tracing effects. If you wanted to enjoy smoother frame rates, you had to drop RT and go for the Performance mode, but now, thanks to the PS5 Pro update, it's possible to enjoy 4K/60 and RT all in one package. It's probably not actual 4K as there is also a 4K/40fps mode for VRR displays, but image quality seems excellent from what we've seen - and so is frame rate. There's even a 8K/30 mode which can even be selected on a 4K display, with downsampling in action for those not wealthy enough to afford an 8K screen.
