Looking at the quick speed test I did above, the download speed here in the land of cheese, garlic and wine isn't too shabby, however the upload is pretty awful. I wasn't filled with confidence. It is important to note that before I left, I had altered my router settings, opening the relevant port for remote play and had also given blanket access for remote management too. I set my PS4 link into action and started the ball rolling. The Vita took a couple of minutes to connect, but I was excited to see my PS4 home screen immediately (I'd obviously left my PS4 on standby back in the UK). The first thing I did was test it with a game.
The first game I used was Battlefield 4. Playing the single player campaign seemed like the best benchmark to use. It looked fabulous on the Vita and the screen scales well too. Controls are a bit fiddly, with the rear touch pad replacing the extra buttons from the DS4, but with time muscle memory kicked in and it wasn't too bad.
There was a bit of lag now and then, unsurprisingly when my family were also using the wifi, and sound blips were more noticible than anything visual. Occasionally the screen would freeze, but with the knowledge that the game was still playing on the PS4 back in the UK, which made split second action in fire-fights a tad fraught. This can mean the difference between life and death, especially in games like Resogun, where there are plenty of dangerous weapons flying around.
Overall though, it was a pretty amazing experience and shows how far streaming technology has come. It will certainly fill my craving for my PS4 games while I am away. It's also been useful to be able to access the UK PSN store while in a different territory, especially during a Christmas Sale. Well done Sony.
