No stuttering here and played the same as per a few posts up
. Installed internal or external? Running insider build?
CODWWII: This would have been end of June when i tried. Never been part of insider. Xbox One X, 4k HDR, OLED tv. External hdd, then transferred to internal, no difference. Digital Foundry commented on it too. Totally smooth until you move a couple of hundred yards and then a hitch/stutter, then totally smooth again. It felt like a loading issue to me. The cutscenes were a bit choppy too like on the ship at the start doing the 5 finger knife thing, but I could have lived with that.
EDIT: sorry if you're referring to MCC, then issues I had were with 1 & 2 only, in terms of stutter. On external. 3,4,5 all smooth though. Others commented about similar issues when I looked on forums. Campaign only, no insider. The issue with 1 and 2 was not on all levels. However when it did happen it looked very much like a frame pacing issue from what I could see. Swicthing to classic mode eliminated the issue, so I doubt its hdd related as it was also independant of moving around when you get the notification that its loading or you're passing a check point. On top of that there is something not quite right with the aiming feel. Made even more pronounced when you get to the later games when the issue is gone.
Halo 4 btw is absolutely stunning in 4k HDR 60fps. It easily competes with some of today's games visually.
