While Sony does not plan to release Killzone 3 on the PC, Yahfz shared a video that gives us a glimpse at what such a PC version could look like. Yahfz used RPCS3 in order to run the game with 60fps, and used KAMI in order to inject support for mouse and keyboard.
The end result appears to be amazing. Now as you will see, the game still displays the PS3 icons. Still, and given the fact some of the recently released PC ports lack proper K&M icon prompts, this can give you an idea of what a rough PC port of Killzone 3 could look like.
KAMI injects mouse movements into emulated games, and can be used in other PS3 games too. According to reports, KAMI also works well with Resistance: Fall of Man.
As a bonus, I’ve also included below some other PS3 games that run on the PC via RPCS3.
