    Which part are you referring to? Outer Worlds?

    Yes. 12 seconds on xss and 53 seconds on x1s. Again it shows 4x~5x loading speed.

    Yea that's running a BC title. I'm not exactly sure if that is the ideal comparison with respect to what new generation titles would be doing .

    It'll will feel odd if smaller, 8th generation games load slower than 9th generation games but we could indeed be looking at this. I recall similar load times with State of Decay 2 on Series X.

    SoD2 was a quick switch, so would have been saving down the prior game state and loading a new one.

    I think with TOW loading we're not seeing the benefits of hardware decompression.

    Everything on current gen is zlib compressed and uncompressed using hardware decompression before the assets are stored in memory. Zlib decompression is still the default way (except textures that will use BCPack) to decompress things on Xbox Series. So this demo has not choice but use Zlib decompression using the decompression hardware as the data is compressed like this on XB1 games.

    Well, it is still that, what MS shows. Just backcompat titles.

    MS needs to really get a focus on newer games here. But I still expect we get many, many loading times. Not really because of the games on the SSD, but because of the games that were backed up on an external HDD and must be copied over to start them. After all even 1TB is not much, and minus OS all consoles have much less.

    Indeed, it is unfortunate that it really does appear that the software side of their strategy has fallen through the floor for this launch.

    In the inside Series S video shows a quick switch between Fallen Order and Minecraft Dungeons. That was under 5 seconds. A bit quicker than the Xbone switching we saw at the X reveal. The 360 games loaded quicker, so not sure if they've optimised quick switch or just that Fallen Order/Minecraft are not using all of the Xbox One's 5.5 GB.

    I could swear there was a tweet about the games running in BC mode and not being ported/ optimized for the SSD. And now I cannot find it.

    Seems possible that the bottleneck is the file processing / decompression (CPU-side ~3-4x faster CPU + it's also Unreal Engine sooo..). Durango was limited to 40MB/s (60MB/s for Scorpio) so the SSD should blow away any bottleneck for plain file transfer leaving it up to processing the data.

    Fair point, switching is a load and a save. And any special efficiencies introduced to make the save faster on nextgen hardware is not going to apply to current gen games unless/until they are patched.

    At the very least all the UE4 games will need at least to pull in the latest engine patch, it's at least UE 4.25 if not a later version.

    The outer worlds and both expansions are optimized for Xbox Series X.
    It is one of the games supporting Smart Delivery.

    https://www.eurogamer.net/articles/xbox-smart-delivery-system-list-6400
    https://news.xbox.com/en-us/2020/07/30/the-outer-worlds-peril-on-gorgon-expansion/

    The outer worlds is not a BC title. It shows about 4~5x improvement of loading speed.
    In fact last loading demo also shows similar loading improvement.


    Does the real world loading speed actually improve 4~6x?

    Description of that video you linked;

    "Demo uses backward compatible Xbox title to demonstrate load time technology and does not represent gameplay optimized for Xbox Series X."

    Optimized is not the same as being built on that hardware.

    I guess for starters: you'd start with compression. That should cut the time down by 50% (in theory)
    Secondly, you only send as much textures as you need to begin the level, so no need to load the level as far out as XBO needs to load it; you can begin the level and be confident your SSD will be filling in the rest.

    So by needing less, and compressing further, you should be able to start the level faster. I suspect this is the aim for next gen fast loading.
