Had a bit of a go with this tonight, unfortunately my router is having a bit of a moment and it's refusing to work on 5ghz so I was stuck in 2.4ghz and the results were not great - stuttery, lots of input lag, audio cutting out etc.
I need to fix my router and give it a fair shot before I can really comment though, hoping that will resolve some or all of my problems!
Yeah I really need to get 5ghz working before I can assess it properly, it would be unfair otherwise.
I did quickly try it with my tablet hooked up to an ethernet adapter and surprisingly that didn't really make much difference either. I may need to explore some further settings on my router to see if it's holding things back in some other way.
Got my 5ghz WiFi working and boy did it make a difference!
Played a couple of hours of stuff last night and, for the most part, it was absolutely brilliant. There are still a few kinks and drawbacks like the occasional artefacts or sound blips and some games displayed a touch more input lag than others (Forza Horizon 4 was not really playable as a result of this) but overall it was very, very impressive.
Forza was fine for me for input lag, it's just games work for 10 minutes or less before the screen freezes up on me and I have to minimize and restore the app. There's also sound issues and the wierd visual stuff going on.
