My small company spends thousands per year on TeamViewer licenses, just because RDP can not attach to running desktop sessions (using Nvidia graphics cards). Do you think this is something that could change in the future, or is it a fundamental property of RDP?

I really dislike our reliance on TeamViewer, especially now in covid times where were relying even more on remote access.

Can you use a RealVNC variant instead? I just replaced TeamViewer with UltraVNC single click for my remote support needs, it’s free, it’s branded with my logo and my clients find it easier to use.

I'm not sure, I think I've tried it but I don't remember what the result was. Note that our goal is decently fast (20fps+) 3d graphics.

I've also tried moonlight (which is an nvidia gamestream implementation), which seems to have performance but the client wasn't very usable for this usecase.

You can try Parsec as well. Not created for this purpose but works very well for productivity. In my experience maintains 60fps.

Oh, yeah it's probably not going to handle that too well. It's not really designed for full motion video. I tried running a game over it and only got a couple of FPS (although that's over an ancient USB WiFi dongle so modern performance might be better).

Still great for general productivity type stuff though!

What issues did you have with Moonlight?

Sorry for the late reply.

RDP/termsrv by design create a new session for incoming connections. However, with Windows Virtual Desktop (WVD), Windows Containers and Windows AppGuard, we definitely have a way of launching remote applications in an existing session.

Have you perhaps looked at WVD or RemoteApp? If you'd like to talk more professionally, you can email me at {first_name}.{last_name}@microsoft.com (my name is available on github.com/zeusk).

This might sound weird, but Steam allows you to stream your desktop for games and provides full control as well as stream of audio and video. Works on any device. Wonder if it could help. Being targeted at games, it has great performance.

Why don't you use FreeRDP, X2Go or rdesktop - all open source???

Those are clients.

WebRTC is the way to the future of open source remote desktops. I don't know exactly by I have a strong feeling that google is using WebRTC for chrome remote desktop

Would you mind clarifying the problem you are facing?

I am able to RDP freely onto desktops with rtx 2070/gtx 960 cards no problem.

Is this more something specific involving some degraded performance/reduction in features?

I have trouble with RDP and a 1060, though I've not tried in many months so it might be something that has since been fixed.

The issue seemed to be switching between remote and local access, i.e using the machine locally, then from remote, then coming back to local. It would usually survive a couple of cycles of this then just be a black screen after login. Once in that state tricks to reboot the graphics driver did not work and reporting in speed working too, though the rest of the machine was up as services like IIS and file shares kept responding just fine.

My hacky solution is to run VM for most day-to-day work on that machine and remote to that, only using the bare metal when I need the fancy gfx card or otherwise the little bit of extra unpf gained by not having a virtualization layer in the mix.

Yeah I work at a games studio, we are fully remote at the moment due to covid, and disconnecting/reconnecting RDP usually crashes whatever is running on the machine at the time, due to "GPU removed" error. Also only DirectX applications work through RDP, nothing OpenGL/Vulkan based. We have some Citrix licences for that.

Are you talking about WiDi? I tried to use that on my 3gen i7 laptop. It was awful experience on Windows 7. Then I switched to Linux and never went back.
