Hi, I think I’m tracking down this fps issue a bit better. It has to do with the resolution it seems. Sometimes when I log in now I will be streaming the perfect 60fps, but if I try to adjust the resolution at all through the NoMachine control panel, the resultant stream will have a low fps. However, if I toggle the fps within Gnome-control-center to something else, the fps will go back to 60fps. (though this isn’t 100%, sometimes I can not get the fps to go back to 60fps unless I kill the connection and reconnect. Also, sometimes adjusting the resolution doesn’t effect the fps.) It is really finicky.
Here are the server side logs for the debug package that you sent. Did you need the client side as well?
Client side is Archlinux with an i7 6700k (running HD 530 graphics) with vaapi and vdpau verified and set up for hardware accelerated decoding.
Bandwidth internally is constant gigabit ethernet, eith steady ping of 0.75ms +-.05ms. Externally, the university is connected with gigabit down and gigabit up, and my home connection (for when I’m not connecting from my office) has 150mb/s down. I don’t think bandwidth is the problem, as i’m reporting only 750kb/s – 2mb/s at any point in time uploading from the server when I’m using it.
This issue shows up when connecting to the same server from three different computers, two on archlinux, one with intel graphics, one with AMD graphics, and a third computer running Windows7 with Nvidia graphics. I wouldn’t think it’s a client issue based on the consistency of these behaviors.
Lowering the display quality has no noticeable improvement on the fps.
Btw, the server is running Ubuntu 17.10 with Gnome3.26, using the Xorg session, with Nvidia drivers 390.25. I’m emailing the logs now.
