Touch Screen Support

[Hawke]

I'm trying to stream to a Surface Pro 3. No problems otherwise, graphics look great, speed is good, keyboard and mouse work but there is no touch support at all. Not even clicking on the screen. Tried Star Realms for something lighter, also tried Civilization as I know touch works fine when played directly on the SP3 (instead of streaming).

Any tips to get touch to work? Updated drivers? I tried matching the resolution as well but no luck.

Does the streamed game support touch screen on the host? If there´s no controller option for touch, it won´t work.

The host doesn't have a touch screen. I guess that may be it, though I tested using the Android Steamlink app on a tablet and touch works fine there. I'm wondering what might be able to fix that. Is there a generic touch driver for Windows 10?

While I don't have SP3 I can share my experience with cheap, under 100$ Win10 tablets.
First, I've tried Steam IHS on Viglen/Tesco Connect tablet and amazingly it worked perfectly. Touch inputs registered properly, however games recognized them as mouse input. Civilization 5 did not recognize any gestures but was still perfectly playable.
(The tablet is a mere 1GB ram model with atom Z3735G but manages to run win 10 quite reasonably, including lagless decoding over wifi).
Recently, I bought Kazam Vision tablet (which is a Linx Vision clone: 2GB ram, x5-z8300, comes with xbox controller enclosure). When streaming to this one, no input is registered at all. Connected external mouse or keyboard works fine.

On closer inspection I think I found the culprit:
The first tablet has "limited touch support" reported by Windows and touch screen's drivers appear under "mice and other pointing devices".
The second tablet has full touch support with 10 touch points, as reported by Windows. There are no devices at all under "mice and other pointing devices". Touch screen driver ("Goodix HID Touch") can be found under HID devices.

I believe Steam fails to recognize more advanced touch inputs, especially when connected via internal buses (I don't have it on hand but I believe the first tablet utilized internal USB while the second uses I2C connection)

EDIT:
Forgot to mention: Host doesn't have touch capability.

Thanks chiveicrook, that seems like it might make sense. The Surface Pro 3 definitely has more advanced controls including things like pen support. That's too bad. I wish there was some kind of list out there to help as we tested this while I'm making a decision to get something mobile that I can use on a plane for movies but also do in home streaming.
