No the issue is the fast loading is part of the gameplay. You can't add 2 extra seconds per dimension portal and still have seamless gameplay like this.
If you have a point to make then make it because you are making even less sense than the guy I replied to who was straight out lying.
Let me help you out with this SIMPLE logic. If thing A can just do something using all of its resources, then thing B can't do that same thing if it has fewer resources than thing A. Come at me bro if you think there is some flaw in that logic.
The Atari Jaguar ad made the point for me, but I'll elaborate. First off, this is a launch title; if you think a launch title is using the full potential of the hardware resources on any system, that's silly. If that actually turns out to be the case with R&C in terms of PS5 SSD I/O, that's very worrying, means little room for growth there over the course of the system life.
Secondly, we still don't have full details on XvA's setup, or the proprietary solutions like BCPack. In addition, we have no idea in what specific ways R&C is using the PS5 resources and that's with other things aside from the SSD. Moreover, just knowing some numbers here and there in terms of specs, even with systems as architecturally similar as PS5 and XSX, doesn't tell you too much because there's a lot of baseline stuff with those architectures we don't know about in terms of deep details.
You're reaching with conclusions here; R&C was absolutely a showpiece for PS5 in the event. But there's nothing much here from what we've seen so far that couldn't be done on XSX when it comes to the asset streaming. There's not too much here to lead to that conclusion. Now, devs might have to use some different techniques for similar results on XSX, and there will be stuff in terms of asset streaming later in the gen capable on PS5 that can't be done on XSX, but we haven't even started the gen yet. These games aren't tapping out any of the capabilities of these consoles, regardless of how great they look.
What was said is that the PS5's SSD is at least 80% faster than the XSX SSD with 4 more priority levels.
Where did we see this confirmed? MS haven't divulged anything on priority levels with XSX's SSD I/O. They haven't really given a ton of details on XvA in particular. You're simply assuming it's 2 priority levels because Sony stated 2 priority levels as a reference on PC SSDs and you're assuming XSX is just using an SSD no differently than a PC, when that couldn't be further from the truth.
Granted, yes they'll take aspects of XvA and implement that into PCs in the future through DirectStorage etc., but that's a case of things going from consoles and influencing the PC, not the other way around.
