Watchdogs 1 & 2 won't load on Xbox One X

Does it give you any error messages and have you done any of the following: Cleared the games cache and/or cleared the system cache?

To clear a games cache:

1. Press the start button on the selected game to go to "Manage game and add-ons."

2. Go down to "Saved Data."

3. Click that and delete the "Reserved Space" save. DO NOT delete the save that has your gamertag as its name (Doing this will basically wipe your saved data).

To clear your systems cache:

1. Hold the power button on the front of the console for ~10 seconds.

2. One the system is 100% off, pull the power cord out from the back of the system and let it sit for around 1 minute.

3. Once a minute has passed, plug the system back in and restart the system.

I have loads of external HDDs

2 x 3TB, 1 x 2TB, 1 x 1TB, 1 x 500GB.

BF4 won't play period. Same with Watchdogs. Both are on disk and just freeze in the startup screen for a while before crashing and telling me that the game took too long to load.

Really looking forward to play it. Loved Watchdogs 1 & 2.

I appreciate the Xbox One X must be faster at loading games but the Xbox One's speed is fine to me.

The loading speeds of the One X are no better than any other Xbox One as they used the same hard drive...it used to take upwards of 2 minutes for my one X to load a particular game!! You aren't missing out there. The One X is really only if you want the 4k content
