If you invested as much as me into the Pro and it's games you might actually understand where I'm coming from. I own all these games and they all were bummers in some way-
sw outlaws, aw2, Dying Light 2 (how did this get a reputation as a great patch?), dd2, sh2, Avatar, darktide, Diablo 4, space Marine 2, Black myth wukong, GT7, dead island 2, gow ragnarok. Mh wilds, ac Mirage, crew motorsport, arhammer Rogue Trader, baulders Gate 3, until dawn remake-its not smooth at 60 fps, hitman 3 (they have the tag but what improvement?), the Hunt showdown
To a degree I agree with you that these games are bummers but I'd also like to highlight some other factors and points of agreement/disagreement about some of the ones I've played on this list. With regards to the games I have played or have more familiarity with:
SW Outlaws in its Quality 60fps mode on Pro is at least equal if not superior overall to the 30fps Quality mode on base PS5 right now imo. Therefore, it's met the Pro's general goal of providing PS5 quality settings but at 60fps. Yes, there is an issue with shimmering with PSSR (the extent of it varies from minor to major on the 40fps mode and from the bit I've seen of Quality 60fps it looks somewhat to be the same case there) but the overall motion stability is significantly better than FSR on the base (and the Pro) and the Pro offers similar, if not better, image sharpness compared to base Quality but at 60fps. So overall, Outlaws is a win to me and meets the Pro's goal, but it's not perfect due to the shimmering (I also think there's shimmering using FSR as well but there's less of it).
Avatar is less of an improvement than Outlaws. It's hard for me to remember how good the base Quality mode looked on my Series X, but if I could hazard a guess the Pro version using Quality 60fps mode with PSSR or FSR is perhaps 70% as good as the base Quality 30fps mode on Series X wrt image quality. I know there is the shimmering issue using PSSR so you can use FSR in this game but that does come at the cost of lower image stability/more artifacting in motion. So yeah, it's better to play this on Pro, but it's not enough of an improvement. It really needs the newest version of PSSR.
Baldur's Gate 3's Pro performance mode is better overall than both the base PS5's Quality and Performance modes. This is a strange game where I actually think the Performance mode on the base PS5 is superior to the Quality mode on base. I think that performance mode's 1080p upscale to 1440p using FSR produces a sharper and overall better image than the native 1440p (though at the cost of more noticeable artifacting on things like hair). But regardless, the Pro's performance mode is better than both modes on base PS5. FSR on base PS5 does produce more sharpness, at least on some surfaces, but other aspects of the image quality bring it down and so the Pro is overall superior. Other than that there wasn't much else they could do with a Pro patch because the base PS5 already ran at a mixture of high and ultra settings I believe and so there wasn't much more they could do there. Frame rates in Act 3 were never going to get significantly better because that's a CPU issue (and NX Gamer says RAM issues are also a factor) and I think we knew that the Pro didn't have a significantly better CPU prior to launch and so this is to be expected in games that are limited by the CPU (the Pro still has around a 10% boost in frame rate in Act 3 though). So I think the Pro delivers a version that is a win, but yes it would've been good if PSSR could definitively beat FSR in every image quality area in this game. Overall though, I think the Pro delivers the better version and other than some image sharpness improvements there isn't much more that could be done to improve this version over base. And I wouldn't consider PSSR to be blurry in this game - it's still a clear and pleasing image. We'll have to wait until the PS6 to get a better boost in the CPU limited areas.
Black Myth Wukong on Pro provides an image that is 4k-like in its Quality 30fps and 40fps compared to the 1440p-like image (and possibly more FSR artifacting? I'd have to go back and check to be sure) of the base PS5. That's a clear win in those modes. It's stupid and ridiculous that there isn't a Pro enhanced 60fps mode but I'm not sure this has anything to do with the Pro but rather due to the bizarre decision of the developer. The Pro and the base consoles seem like they could have a mode that runs at 60fps but for whatever reason the developer hasn't done it. They appear to think their frame generated pseudo-60fps is good enough. I don't understand why this mode exists but I don't think the Pro not having new 60fps is because of the Pro specifically but rather due to the developer's strange decisions. I'm pretty sure that if you move to PC one day you will also find some games that don't perform to your expectations because of developer decisions or strange technical problems. This is a problem everywhere and likely will be with us for a very long time, if not forever, so moving platforms won't fix everything for you.
I do agree with you that Space Marine 2's Pro performance mode should have the ultra textures or similar settings as the quality mode on base. It's a pretty sizeable improvement in image quality over the base performance mode but it should have settings parity with base quality mode, even if required a bit of a drop in resolution. I don't know what's going on here tbh. Again, maybe it's a strange developer decision or perhaps there is a technical limitation in the Pro. Still, it is a win, but not good enough and doesn't deliver on the Pro's aim of base PS5 quality settings at 60fps.
I am disappointed with the image quality of PSSR in GT7 so I agree with you there. But Polyphony Digital are very consistent in updating GT7 so perhaps we'll get an improved version of PSSR this year. Other than that I didn't really gain a lot of benefit from the ray-tracing in gameplay but tbh I haven't played it much since the patch so perhaps I need to race in more scenarios. I'm pretty sure I noticed a nice increase in frame rate in the quality/120hz mode so that was nice. VR was improved as well (but I don't have a PSVR2) But, yeah this is not a good enough update imo.
Dying Light 2 on Pro didn't seem very good from the very little I played, so I think you're probably right there.
GOW Ragnarok seemed fine to me? What are the problems with this one? I only played a tiny amount on Pro since I've already beaten the game on base. But base had great image quality in performance mode already so was there really much room left to improve?
I've played a little of AW2 on Pro and just based on limited impression I can't say atm how the Pro's performance mode compares to the Quality mode on Series X. I'm pretty sure it's a significant improvement over the Series X performance mode though since the base console performance has some very poor image quality in motion. But I'd have to play more or compare more the see how close the Pro's performance mode comes to matching the Quality mode on base. But I don't want to buy the game again on Pro, at least right now, because I didn't think it was that great of a game.
The Crew seemed fine to me but I only played a very small amount. The image was sharp and it runs at 60fps. I never played it on base PS5 though.
