To re-iterate on a previous post, every day I grow more and more pleased with the speediness of this processor.
I regularly use Netflix, Twitch, YouTube, the built in Chromecast, external USB drives with videos on them, even the internet browser.
I also regularly tweak the settings based on what i'm watching.
The TV is such a pleasure to use compared to the X900F. The remote is quick and snappy, so are all the menus, I can have multiple apps running in the background and switch between them almost instantly.
One thing I have yet to notice however, is the benefits of the X1 Ultimate over the X1 Extreme.
I haven't watched much cable yet, but I assume that's where we will see the power of the object based super resolution (is this tied to the Reality Creation setting?) I will be watching some more cable in the next few weeks and report back. I did read that Sony said this processor is twice as powerful as the X1 Extreme mainly because of their database of objects to re-master in 4K and HDR. So I assume this benefit will be seen the most with low quality content such as compressed 720p cable.
