I've installed that tool on a variety of Geforce gpu's today using the latest 'doom ready' drivers. 960, 1060, 1070, 1080ti, 2060, 2080ti. Opening a simple Revit model over RDP, Enscape runs. Performance is about what I would expect through an RDP session.
With Quadros, we have been able to generally run Enscape through RDP for the past few months, without too many issues, but occasional crashes from what I've heard. Users also don't report every issue to me.
All of my Enscape 2.7+ installs include an additional install of the VC_redist otherwise it just hangs. I fully understand that Enscape doesn't officially support usage over RDP, so I warn users that they may experience crashes.
If some of your users are having strange behavior, check which version they are running. I've had issues with a couple people where 2.6 is uninstalled, 2.7 is installed, but somehow the user is still running on 2.6, so there are some items left behind which need to be cleaned up. The same with different versions of 2.7 msi, where I put the latest version on and they still get a popup that there is a newer version available. After doing some manual cleanup in the usual locations, they are good to go.
This tool you linked is great news, as we have a wide mix of cards, not all quadro, and it sure seems like remote life will be lasting much longer than we predicted about a month ago.
