You seem to be equating optimization with design. They're not the same thing.

i think Halo 5 will flop, MS needs new IPs.

Really interested where they're going with it. Will it be 720p never dipping below 60fps or will it be 900p with noticeable drops. I'm not familiar with the fanbase of this game but would an option to have 1080p and locked 30fps be used at all?

Thats what they say about every halo game ever. It will succeed. And let's ignore sunset overdrive and quantum break which are 2 interesting new ip's coming soon or have already arrived. 

Games are usually 2/3 years  developement.  A year or 1/3 the time of developement is definitely not that long.......

The beta (an actual beta, not a glorified demo) is about the gameplay first and for most.

Who says it can't be 900 without noticeable drops? Other games have done it. 

I really wish Digital Foundry would go out of business. They have been a bigger detriment to gaming than an asset. 90% of people can't tell resolutions and framerates unless they are told. People who have played thru beta have been enjoying it and the these guys come along trying to tell people they should be disappointed.

But have you played halo 5?no you haven't. So you don't have an opinion until then about it being slow and whether or not It needs change

well this time its different, this time its not made by bungie and the install base is much smaller on the X1. I think it will sell 2 million units and get mediocore reviews

Which games?
