PSSR was supposed to be the cherry on top. Instead it has become the crutch used to compensate for underpowered pro hardware. The truth of the matter is simple, the ps5 pro cannot 2-4x the resolution like the ps4 pro did on merit alone.
If it could, a lot of devs would not bother with PSSR and if they did, most PSSR implementations would be better. It would be better because the base input resolution would be higher masking the flaws of the first iteration of PSSR.
PSSR is supposed to be a testbed for sony's next gen ambitions. It's been an unsuccessful test so far.
This is exactly my point my friend....PSSR was never meant to be the "cherry on top". It is THE CORE/INTEGRAL piece that makes this system an advancement over the base console. That's where everyone gets their expectations and judgements out of whack. That's where Sony spent the bulk of it's time and money in developing the PRO over 4 years. The machine learning aspects of the system is the true advancement and integral to all of the value that comes with this PRO system.
Go back and watch Mark Cerny interview on Project Amethyst and next gen. If you pay attention, you'll hear him say something that a lot of people still aren't fully grasping...when he talks about "power" he refers to it as "
effective power". All of the innovations coming with Project Amethyst (neural arrays, universal compression etc.) he referred to as increasing the "effective" performance, bandwidth etc. The reality of the future of gaming is that the raw HW specs are less and less relevant and AI will be a performance "accelerator" (as he called it as well). We can clearly see that the difficulty and expense in scaling the physical hardware means that we are hitting a wall in how much additional gains we can get with building larger HW. It's just not practical anymore.
~10 years ago, it was possible for Sony to build a PRO console with a >2x larger GPU and higher clocks on the CPU and GPU for the same price as the base PS4 at launch. Why? Because by the time the PS4 PRO released, the base PS4 was in fact
cheaper than it was at launch. Fast forward to 2024, and the base PS5 was actually
more expensive than it was at launch 4 years earlier. So any increase in physical HW is going to come at an additional cost. That's the reality of the macroeconomics of computer HW today.
So AI is the solution to deliver the performance gains people expect. PSSR is just the start but it should theoretically increase the
effective GPU performance by reducing the load on the GPU freeing it up to do additional work that couldn't be done on the base system. How? For example, a game running at 1440p/60 internal on the base console with a 4K upscale (i.e. TAA) can theoretically run at 1080p/60 internal on the PRO and use PSSR to deliver the same or better IQ at 4K. That is roughly 1/2 the load on the GPU (this is why many PRO titles run at lower internal resolution than the base because
THAT IS THE POINT OF THE SYSTEM). So you have a GPU on the PRO is ~50% larger with more CUs etc (that is roughly 5ms of additional headroom on a 16ms frame for a 60fps game). Additionally on the PRO, it also is only rendering 1/2 the number of pixels so the cumulative bump over the base solution is actually well over 2x in that scenario (yes accounting for 2ms to run PSSR and other time lost on latency and inefficiencies). In other words,
effectively, the graphics performance of the PRO is
more than double that of the base in this example using PSSR. That is the vision and dream of the PRO.
Now yes we haven't seen this realized in every game released on the PRO, but let's not act like we haven't seen many cases with and without PSSR where the PRO is delivering way more than the "+45% rendering performance" figure will suggest. We've seen pixel counts increase by >50% to more than double in the best cases (ex. Returnal, Helldivers 2, Baldur's Gate 3). We've seen framerates increase by >50% with the same settings on the base (nearly every 1st party Sony title). And the PSSR 2 update is supposedly way more efficient meaning it'll take less overhead to run than the current model. That will "give back" even more GPU time to push perf even further. Stay tuned...
