Did you ever think maybe they were lying and only singing praises to MS because MS paid for the marketing rights on Dirt 5? We've staright up had other developers say that the tools were late and radically redesigned compared to what they were used to on Xbox One *shrugs* Like I said, we will find out within a few months, if these launch games get patches that bring the Series X versions in line with the PS5, and if newly released 3rd parties in the coming months show smaller PS5 advantages and an eventual Xbox lead over time, we will know that it was a late tools/devkits thing. I can wait a few months to find out, I'm not in a rush to see which console is the real performance king this gen, can you wait to find out?
There is also a possibility that PS5 just might be easier to code for, easier to extract its performance than Series X. This is the very thing Cerny spoke about. MS made no mention of the same for their dev focused presentations. Each company has really laid everything out quite clearly in terms of the drivers behind their next gen console vision, and I don't get why gamers are ignoring the actual company that makes the console.
That being said I expect parity very soon.
And that is also part of why I find this whole thing strange. The new Xbox Game Core dev tools were designed to make Xbox development easier, the entirety of Series S | X and the Game Core dev tools were designed to make Xbox development more PC like, so that developers could easily port their PC version (which is the version that most developers make first) onto S and X, choose the PC resolution and graphical settings which make the most sense for each console, and then optimize to hit those settings with a good framerate at the desired resolution. With Series S and X being more PC like than ever before, optimizing for them should not be difficult, and yet both Series S and X are preforming below expectations on launch games.
That tells me the answer for the poor performance is one of 3 things personally:
1. The late tools/dev kit rumors are true, and devs just didn't have time to used to Xbox Series ahead of launch. This theory makes the most sense to me and has been backed up by some indie devs I believe I read. These consoles were coming in hot during a pandemic afterall, and we've had rumors all year that MS was behind schedule during development. I mean just look at how many of their 1st and 3rd party launch window exclusives have been delayed out of the launch window, Halo, CrossFireX, 12 Minutes, The Medium, The Ascent, The Artful Escape, that reeks to me of dev kits and tools coming out late.
2. PS5, despite having on paper lower specs except for the SSD speed and pixel fill rate, is easier to develop for in spite of Microsoft's effort to make porting from PC to Series S | X easier. Possible I'd say, but not as likely as the delayed tools/devkits.
3. 3rd party devs are just being lazy and don't want to optimize for both S and X, and are just porting over some lower PC settings instead of optimizing to hit higher settings on each console. If it was just Ubisoft's launch games having issues, I'd say this was the culprit, as they are well known to be lazy optimizers, but Dirt 5, which MS had marketing on, is also behind, and PS5 also has an advantage in one of DMC 5's performance modes. I don't think this is the issue personally.
