Like the others I can’t speak to xbox remote play but here is some info about similar solutions!
PS4 Remote Play – Windows App – Works okay so long as you do *NOT* choose the high frame rate option. 720p (hi res) is fine but if you chose high speed (i.e. 60fps streaming) the decoder loses sync and you get a tone of broken frames. Since most PS4 games are 30fps this isn’t the end of the world but I also suspect it has to do with Sony having very limited hardware decoding support (if any) and it would not surprise me if the Ps4 remote play app was relying 100% on software decoding which would definitely explain why the Atom chip in the Hi12 can’t handle 60fps.
Steam In Home Streaming – Works for the most part. We definitely hit the limits of the hardware decoding engine thought. If you try to get your stream quality to beautiful and 30mpbs (or even unlimited) it overwhelms the decode engine and you will see frame loss (i.e. skipped frames) from 18-35% which results in a very very chopping experience. That being said dropping the stream quality down to normal and limiting bandwidth to 30 or 25mbps per second results in a nice stream. At 25mpbs I see zero frame loss, at 30mbps I see it hit 1-3% at times which is borderline imperceptible. If your playing on the tablet itself you would have a hard time spotting the difference between normal and beautiful setting, if you plug it into a TV or projector though you might see it (effects compression artifacting which can result in smearing and macro blocking).
So the Hi12 is essentially completely up to the task of streaming games, but based on my experience with Steam (which has great hardware decoding support for Intel chips including the Atom) but it appears Sony (and I would speculate xbox as well) are not as finely tuned so your results may vary.
