It was also supposed to be Ray Tracing ...remember Cerny's "3 pillars"?
We haven't seen RT improvements in many games at all ....ratchet and Spiderman amd that's it. I don't count GT7 because the game looks downright bad with RT and pssr.
See here is where you're stretching to highlight what's lacking without full context. Sony 1st party studios by and large haven't released many RT enabled games at all! In fact, only the Insomniac games and GT7 feature it in any meaningful way for visuals. God of War, Returnal, Demon's Souls, Horizon, TLOU Pt1/Pt2, Astro Bot etc...none of them feature RT on the base PS5 (or PC) so why would you think Sony would add it for a "PRO" console? The PRO's job is to take the PS5 experience and elevate it via IQ or perf improvements not to recreate the wheel or add new features to PS5 games. My point is this is not a PS5 PRO problem but rather a Sony studios problem at large.
Perhaps you also underestimate just how much work it is to add Ray Tracing to a modern game engine and pipeline. We're talking years of work to build it into an engine, art pipeline, and tune it. Even some of the more meaningful RT improvements for PRO took many months of work to do (i.e. AW2, AC Shadows, GT7) which is not something most developers can afford to do for a relatively niche low volume console.
Furthermore, it's completely disingenuous to dismiss the GT7 RT enhancements on PRO due to poor PSSR quality. Fortunately, Polyphony added the ability to disable PSSR while still keeping RT ON and if you do that you retain the pristine 4K image while getting RT reflections on external car bodies during gameplay and replays. This is still a meaningful improvement over the base completely independent of PSSR even if you miss the internal RT bounces in the cockpit view.
We really need pssr to be fixed/revised for the huge initial batch of Pro patched games because so many of them suffer from aliasing and Pssr specific artifacting.....not that we ever will see this happen though but games like Alan Wake 2, Avatar, SH2 and Dragons Dogma 2 all have barely better image quality than base ps5
Actually, in the case of SH2, DD2 and Avatar IQ is actually worse on Pro. The waterfalls in Avatar are disgustingly artifacted. SH2 we all know about and DD2 has really messed up ambient occlusion due to pssr. Digital Foundry even covered that one.
SW Outlaws, GT7, Datktide, Hogwarts Legacy all have significant issues too. If you play GT7 with RT on and pssr looks like a blurry mess ...until recently I was getting raked over the coals pointing these problems out to people but seems like recently people are starting feel like Sony is half assing Pro support.
Really?! Pretty much every 1st (and 2nd) party PS5 game has a meaningful PRO improvement taking advantage of the "BIG 3" where appropriate. As I mentioned, all of the games that support RT on the base console sees enhancements on the PRO. Nearly every major Sony PS5 game leverages PSSR on the PRO for IQ and perf improvements and there is far more effective and consistent use of VRR, unlocked frame rates, and fast loading from Sony 1st party. From Demon's Souls, Returnal, Stellar Blade, GT7, TLOU Pt1/2, Astro Bot, and SpiderMan 2 to the recent Days Gone Remastered and Death Stranding 2, you're going to see some of best examples of what the PRO has to offer (PSSR, 60+ FPS, RT enhancements). Furthermore, they've been great about upgrading the SDK and PSSR quality and performance for devs behind the scenes and working closely with key devs on their PRO upgrades including Ubisoft for AC Shadows, Kojima for Death Stranding 2, Shift UP for Stellar Blade, and Square for FFVII Rebirth.
Your problem is that you focus so much energy on what the PS5 PRO isn't doing or is lacking but putting the blame in the wrong place. Sony doesn't develop any of the games you're complaining about here except GT7. Those other games would fall on the dev to update their PSSR and patch the games. It's a question of how much time and energy they want to put into their PRO upgrades. It's not a simple swap of a DLL file to get the desired results. In most of these cases, it may require a bit more engine (and in some cases) art work to get the desired quality.
Also, you pointed out like 8 games here with issues out of the roughly 100 games out there with PSSR support. Point being that in the vast majority of cases, PSSR looks way better than FSR or whatever solution is employed on the base PS5.
That doesn't change the fact that there are not many games taking advantage of the Pro's extra RT performance.
My expectations were higher than most but still in line with Sony's own promises for the console.
Again, the vast majority of games that feature RT on the base PS5 to some capacity have indeed seen enhancements on the PRO. Hogwarts Legacy, First Descendent, Dead Rising Remastered, Alan Wake 2, F1 24/25, Callisto Protocol, AC Shadows, Dragon Age Veilguard, Jedi Survivor, Fortnite, MH Wilds, and the aforementioned 1st party Sony RT titles are just some of the games with enhanced RT on the PRO.
Your second statement here is the root of your problem: Sony never
promised anything and they know it would have been silly of them to do so since they cannot guarantee what features a dev would integrate and what the results would be in every game. Their job was to make a canvas for PS5 enhancements and entice developers to use it with what is
possible if the system was fully utilized. However, they can't force them to implement anything for an "optional" PRO console.
