Just consider that performance will be highly dependent on your computer’s hardware.RPCS3 is an open-source PC emulator for PlayStation 3 that allows you to play your favorite PS3 games on your Windows PC.
It has a substantial amount of games already supported, some of which will allow you to play them in full.
Considering that the PS3 is an outdated device, this emulator will allow you to experience those games on your current PC all over again. RPCS3 is a great alternative to purchasing the Playstation hardware. Every character, item, and landscape in the game appears smoother than before. The benefit of higher resolutions should also drastically reduce the jagged edges that you see in the game. Take note that that simply rendering existing textures at higher resolutions doesn’t give the same detail increase than you’d see from games developed in 4k. RPCS3 also offers the option to force sixteen anisotropic filtering (16x AF) which dramatically improves texture quality. The better the hardware that your PC is running, the better the simulator will be able to operate. It can also depend on the PC's specifications as the emulation workload of RPCS3 depends on CPU hardware.
At 4K, the drawings look more vivid and more flowing. Games with two-dimensional graphics tend to improve the most. How much RPCS3 can change in a game will differ from title to title.
