The Ratchet & Clank Trilogy [BCES01503]

Frame-rate is too low imo. Try different settings e.g using Mega block size instead of safe, try 1-4 preferred spu threads etc. Ideally the game should run atleast at a locked 60 on a 9700k, frame-rate is really important here because the game-speed is tied to the games frame-rate, so 30fps will be half-speed. And if you aren't even maintaining 60fps on a 9700k most users will be running it at around 30fps or lower in intensive areas, which isn't good enough.
