Thats what I had to do in the end, even after that though it still wasnt finished. I think I do have a broadband speed problem but cant fix right now. It infuriating as i get the game ready for an all nighter and it refuses to let me play.

its annoying that the 2 games where its been the biggest issue are both major Microsoft realeses. I got Deus Ex and Mirrors Edge recently, neither of them gave me this issue.

Yeah it's just how the cookie crumbles man. They use different install solutions for some reason, every PS4 game I've had installed in seconds and the full game way available so I'm not sure what some in the thread are referring to.

SONY has put great efforts into avoiding long install times inconveniences. The PS4 has a separate processor/separate RAM that handles background processes, I've seen it in action and it works like a charm.

You have an issue with the updates and thus your internet speed, not with the install times.
Halo 5 is too big for one Bluray so you had to download the rest (MP).

Install it without internet connection or while having the auto install updates option turned off and you will be able to play the campaign.
If not the update will be downloaded during the install procedure.
Game installs take between 20 and 30 minutes on BOTH consoles (if its a big game that nearly fills the bluray). The difference lies in the fact that you can start playing them much earlier on PS4.

The Xbox One can do it all without requiring the seperate ARM chip and DRAM.

It's completely up to the developer on Xbox, where-as Sony has probably made it a mandate.
The PS4's seperate chips don't tend to accellerate the transfer rates from the BD-ROM drive anyway, which is the real limiter.

Yes, it can, but it most of the time, it doesn't. Why? I have no idea.

The developers already make it possible on the PS4, and we never heard them complaining. Why aren't they taking the time to do the same on the X1? do they really need their arms twisted when they already do it for one console with a very similar architecture? I dont own a PS4, but I gotta appreciate what SONY has done here, the PS3 was a PAIN to deal with in that regard. 

I'm a PS4 and Xbox One user.

A lot of ps4 games that I own let you play almost instantly. A handful of Xbox One games have allowed the same BUT when I uninstall them and then reinstall them later, they take much longer (ie Sunset Overdrive let me play in five mins the first time but when I played it on my second XBO, it took over an hour!)

At the same time, some ps4 titles have lengthy updates before you can play online so it's almost like being in the same boat.

Lately, I just let games on either console fully install and update. It's just easier that way. And I've been more of a digital gamer these days anyway. I haven't bought a disc since Valkyria Chronicles on ps4.

You know the thing I can't stand, when you boot into a PS4 game which turns out to need it's patch to connect to servers, say I accidentally opened Star Trek online without patching it, so I get a main menu, which tells me it needs to be patched to go online, Click X to confirm or O to cancel.... like pressing X just retries logging in with a version which doesn't work and press O and it loops to the same message again, just hounding you with it in a loop til you press the ps button and exit the game fully from the menu. Fucking stupid system if a game is online only it should be a case of "Hey you really need that patch bud, I'll close the game for you and you can apply it if you want with a press of X or you can just close the game with a press of O" would be so much less annoying than a loop of "YOU NEED THE PATCH, X TO OKAY THIS FACT, O TO NOT OKAY THIS FACT, BOTH OF WHICH WILL TELL YOU ABOUT A PATCH."

Tee hee how long do you sit there pressing X and O for? Please say it's like 5 whole minutes.

IT'S BEEN 5 WEEKS NOW AND I'M STILL PRESSING IT!!
