The PCSX4 is the newly developed PS4 emulator that allows you to play the PS4 console on PC for free. The down side to it is that you might encounter some lags while playing PS4 games (using PS4Emus) on your PC, but you are less likely to even notice them.
This emulator was originally introduced in 2013, and after over half a decade of tweaking, upgrade, and modifications, the latest update (optimized package) was released.
