    Yeah, I realised I had mis-read the post and I mis-remembered the post - apart from that it was golden! I am curious if the PS5's decompression hardware is accessible outside of the I/O. Logically it should be accessible. Equally logically, why would it need to be. :runaway:

    Good video and very interesting, however for someone so clever to suggest not putting the XSX 'on it's side where the holes are because you'll block the vents' I had to wonder (seeing as if you were using the console it would be impossible to block the vents)! Also, that vent on the back of the XSX I'm pretty certain is a kind of a safety vent for if some kid/mum puts something (or something maybe falls onto) the top of the XSX...it may help with acoustics but it is 100% not for helping get the back of! lol

    I ... can’t believe Sony actually updates their store info with the latest install size. Let’s see, Gran Turismo Sport and Days Gone would be good test cases for very different original vs updated file sizes and ... yup, GTS lists 43GB (60GB on the case) for what is now a ~100GB install (and you have to update it if you want to, you know, Sport). Days Gone lists 39GB (46GB on the case) for what is now a ... huh, 38GB install. Respect.

    Control’s PS4 case says 40GB minimum. PSN says 24.46GB for the original and 24.45GB for the Ultimate Edition, neither of which explains why Control takes up 34.33GB on my PS4 Pro. (It looks like the two expansions were added onto my base install courtesy of the Ultimate Edition being free on PS+.)

    In conclusion, PlayStation may be for the gamers, but their store is for the birds.

    Btw, can somebody check how much space control really takes from the ssd?
    We had reports here (in this forum), that if you install a game, the info screen shows x GB but after installing a game the ssd was filled with more than expected as the system part also increased. I'm just curious if this is still the case.

    Thx.
    So, that could mean they might fixed a bug, that more space on the SSD was allocated in the system part.

    It says unoptimized will benefit more. So if a game engine is optimized, what is the result?

    a game engine optimized for the PS5 architecture will benefit the PS5 more.
    a game engine optimized for the XsX architecture will benefit the XsX more.

    Third party devs may choose a middle ground, or favorise one or another arch depending of their needs.

    He says some unoptimised engines will benefit more from wider and slower, some from narrower and faster.

    Much like, at the start of last generation, some engines weren't designed to make use of multi core CPU's, so they would have benefited more from a single 10GHz CPU core than they did from the low frequency, high core count CPU's.

    Naughty Dog, however, already had an excellent multi thread utilisation system from The Last of Us (probably from Uncharted too, but I only remember seeing videos from TLoU,) so they were able to hit the ground running.

    Optimised titles are going to be interesting to see, but also inherently difficult to compare as we'll never get the same game equally optimised for each system.

    What the game is trying to do and how it's trying to do it is also a sizeable factor on deliverable performance. An engine may well favour one GPU (AMD or Nvidia) or slower/wider or faster/narrow architectures but fundamentally if what you're doing doesn't also fit you will have other hurdles to overcome.

    * XBSX maintains a slightly higher dynamic resolution on both ends of the spectrum (upper/lower bound), while the PS5 has better anisotropic filtering and near locked 60fps.
    * Since this is a demo, hopefully, AF will improve on the XBSX, and maybe a lower dynamic resolution for a more solid 60fps experience.
    * XBSS is well, XBSS...
    * Just as an FYI, Outriders runs on the Unreal 4 Engine.

    Wrong thread
    Does indeed look like they need to be a little more aggressive with the resolution drops on XSX. Looking at the numbers, maybe something like 10%?

    Interestingly, that might bring the 15 ~ 32 % resolution increase of the XSX back down into far more usual territory of something very roughly like 4 ~ 19 % (using a very basic guestimation). Maybe less than that.

    Right now, without a VRR display (which I don't currently have) I'd probably rather play the PS5 version. Resolution is nice and all that but smoothness is just lovely.

    They're definitely using a better compression scheme or at the very least, some 12.6GB of (redundant?) assets weren't needed anymore.

    Ps5 has better AF, but i read somewhere XsX had better quality shadows, is that confirmed ?

    Probably both. I think it's oodle textures + getting rid of redundant assets. That way they can still load the game the PC / Xbox way (with the CPU).
