1) When interacting with the remote desktop, I get a lot of OS ding sounds (like each time an app is started, new window is created) – known issue, way to resolve?
This has been reproduced in our labs and it is currently being investigated.
2) When you logout of the remote desktop (logout of Windows), the image does not update to the login screen, you are stuck at the image just before logout. Is this by design? Seems like a bug to me.
This should be fixed with the next software update.
3) Do the graphics options in preferences apply only for serving? In other words, if I make a change on my client !M, will that affect how the server streams the graphics? (The UI is not clear on this matter.)
Those settings only apply when the machine where you are doing the changes on acts as a server. If you change preferences (from the NoMachine tray icon) on the client machine, those changes won’t be exported to the server.
Anyway, there is a different set of settings that affects the way the server streams the display. Those are the ones that can be tweaked from the NoMachine Player toolbar during the session.
4) In Performance preferences, there are options for framerate and display encoding, and both are unchecked by default. If these are unchecked (i.e., no specification made), what values are they using?
Default value for framerate is 25 fps. The encoding method depends also on the decoding capabilities of the client. If the client supports H.264 decoding (by means of the hardware or by codec libraries), then H.264 will be chosen. Otherwise VP8 encoding is always used. MJPEG won’t be used unless it is explicitly requested.
