My initial thoughts on the X1X.
Damn console is heavy, but for an OG X1 owner the size of the console along side my PS4 Pro and OG Xbox, I have to say it gives the impression of a very well built system.
Install was about as basic as it comes if you are moving from an X1 to the X. I saved everything on my external drive including my profile, plugged the drive in the X and was up and running less than a few minutes.
I wanted to play something quick so I download the Killer Instinct 4K patch and then compared it to the OG X1 version as I switched between the 2. Not sure if its night and day but its close. Definitely the 4K textures really pop on my set and I was pleased with the control speed and load times which I could definitely feel.
The console is definitely whisper quiet
I tried a few 360 titles just to see how they scale and I noticed the loading times on a few right away. I will definitely get a better chance to really put the console to the test when I get home from work today.
