A single SPU is simply faster than any single core in the PS4 for tasks ideally suited for it, and PS3 games go to great lengths to structure its performance-critical code so that it's a good fit for the SPUs. I realize this will be mostly speculation and educated guesses, but I love talking about this stuff, even if my level of knowledge on this is pedestrian at best.įor Sony, the big problem with emulating the PS3 SPUs would not be their complexity, but the mismatch between the performance characteristics of the SPUs and anything available on the PS4. Is the console powerful enough to, at least, emulate at native settings with no other improvements? Could you force better resolutions without compromising performance? Could badly performing games find enough power to stabilize them? Plop the disc or download the digital version you bought on your PS3 and it just runs it right out of the box. I'm talking straight emulation, no compatibility patches or anything. Which brings me to point of this thread: realistically, how much could Sony achieve with a PS3 emulator on the PS4?
Reverse engineering alone has gotten the emulator this far, so imagine if they had access to the entire technical documentation and know-how that Sony has on the PS3. With a good enough computer you can even force them to render in 4K with better framerate. A good amount of games are already playable with minor to no noticeable issues. It's impressive how far along RPCS3 has gotten already. Before I start, please, hold your drive-bys and witty replies, because this is not about whether or not Sony will do it or how many remasters they want to shove down our throats, but rather if they were to do it, how capable would that emulator be considering the limitations of the PS4 hardware.
