It’s best used for desktop apps and things like PowerPoint. It starts to lose frames and have tearing when doing video. I doubt it would be acceptable for any gaming.

It works well enough, but it’s not going to satisfy people who are concerned with things like benchmarks and FPS.

Nothing to measure it with but i never think about the lag when i do it over hotel wifi

I believe this exclusively uses WiFi direct and skips the AP completely, but I can't completely confirm with a quick google.

Yep, it does - the underlying technology is based on Miracast and works only with Wifi adapters made by Intel because it's point-to-point. Sadly it doesn't work through an AP connection at all.

Works simultaneously here, Intel and most phones support multi-role.

Yes, I just mean it doesn't work over your WiFi connection, so you can't connect another device elsewhere on the network, it has to be in range.
