If it is Cloud Play being discussed then yeah, it’s been horrible of late. No doubt the Weekly Quest refresh and big title launch of Starfield contribute but I noticed it went over the cliff a while back. Like from instant loading of Cloud games and decent play to extreme wait times of 10s of minutes and when eventually loaded (when I had that much patience) game play was too laggy to be worth any waiting.
It seemed to start soon after I decided to heed the writing on the wall, just before Xbox officially canned the old Game Pass for the “new and improved” Game Pass aka Ultimate. I think a lot of other people likewise jumped in with both feet and are giving Cloud Play a tryout, and MS didn’t anticipate the flood. But, that’s just my opinion/experience comparing when I was Cloud Playing quite ok on another account before compared to after. Same internet, same Xbox, only difference is the account and being after the old Game Pass retirement was imminent/announced.
Cloud gaming is handled by custom Xbox Series X hardware, not the regular Azure infrastructure, so it’s probably not as readily scalable as other services. They need to throw more of their custom hardware at it. Maybe reconfigure some things, too, like using Series S hardware for less intensive games, things like Vampire Survivors or 360 titles, or Azure for Play Anywhere titles that can run on PC.
I can imagine FM will make the waiting times really terrible in at least it’s release week alone given it’s the only way XB1 owners will be able to play it, and even those that don’t actually intend to play it will still probably be briefly jumping in to get their E-Ray in FH5.
