Why isn't Quantum Break playable through Xbox Game Pass cloud streaming?

Hi Tired8281. My name is Kyle and I'm an independent advisor.

Not all Game Pass titles are available on Xbox Cloud Gaming, this can be due to many reasons. For instance, some titles simply do not work well with cloud gaming and may require additional optimisation work from the developer. There could be licensing issues preventing the game from being added to Cloud Gaming.

I believe for Quantum Break it would be down to Remedy Entertainment to add support.

Thanks,
Kyle
