Game Pass beta with huge lag to load quests

I noticed MAJOR lag during the Thieves guild quest where you have Karliah and bjorkforkjkjkilkjk with you in that huge dungeon. I changed from the nightingale armor to a steel armor because I was getting shredded and the lag went away... Immediately. IDK
what's up with that one

Last night I have been experiencing game lag where the game during game play stop, and go, stop, and go it really became annoying. I stop saved, re-loaded that save to see if that would help with the disc lag but nope it was still there.

Also, I deleted some of the old files of my game play, and you know what happen, I can’t get back into a quest I need to finish that quest is Mind of Madness. I go to enter into the hallway at Blue Castle and it just freezes up. Again, I saved and re-loaded
from that spot and no good. I still can’t get back in it just freezes up. It is the last part of that quest I am tried carrying around this dues hip bone.

If you are an Insider in the Skip Ahead, Alpha, or Beta rings, then there should be a quest in the Insider app for Game Pass Ultimate; under Insider Content.

Also, it's currently only available in certain regions (English speaking Xbox Insiders in the US, UK, Canada, and Australia)

The Metro series quests are NOT apart of the Game Pass quests. Metro Exodus is not included in Game Pass, so that quest is not applicable when it comes to completing "Game Pass quest master" quest. I verified this through offical support, and checking
that it does not show up in the applicable quests in the Game Pass app on iOS or Android.

The Metro Exodus quest is just a seperate bonus promoting Metro Exodus, 2033, and Last Light. You do not need to complete it to finish the Game Pass quests.

See if your tv has a game mode,this turns off all extras that give the impression of lag.
