Sender stuck on 1FPS after long while without usage

[beep_boop]

Hi.

The situation:
I connect to my remote workstation, on the same LAN connection, a machine that lies about 20 meters from me, and all works fine, 30 FPS easily, up to 60 if i want to.
If I stop using the remote machine, and come back some time later, 15/20 minutes perhaps, the performance of the machine drops to 1 fps.
If I go to the physical machine to check, (screen blanking turned off) the performance is fine, works as it should, but on the receiver i can not go past 1 FPS.
If I log off and login again on the sender machine, then the performance is back to normal.

Logging off and on is non-optimal as m y datasets are quite large and take several minutes to load each time.

I have tried disabling screenavers, and locking on the sender machine, but it does not improve.
I have tried leaving 3D content rendering on screen, but it does not help.
It seems that if there is no mouse/keyboard interaction with the remote machine, then the performance will be stuck at 1FPS after leaving the remote machine unused for a while.

My sender machine:

HP Z840 (same config as the receiver machine)
Remote Boost V20.4.0 - rgsenderconfig restored to defaults, to be extra sure

Linux Xubuntu 20.04.6 - fresh, clean installation

Nvidia RTX3060Ti running latest drivers (570)

My receiver machine:

HP Z840 (same config as the sender machine)

Windows 10 64bit

HP ZCentral Remote Boost Receiver

Version: 20.4.0.8886 (3a328f4d3)

Build Date: Mar 14 2022

Thanks.

Hello, 

Thank you for all of the details.  I would like to have you try V20.4.2.9063 release.  We made some fixes that might help you.

Can you reach out to me at zcentral@hp.com?

I will have to provide you with a drop box (ftp) for you to download the release from.  Reference this forum post title in your subject line.

Hi beep_boop, Thanks for sharing such a detailed description of the issue! It sounds like the remote session is going into some kind of low-power or idle mode when there’s no interaction, which is causing the drop in FPS on the receiver side. Since logging off and back in fixes it temporarily, maybe try checking if there are any power management or display timeout settings on the sender machine that might be throttling the GPU or network during inactivity. Sometimes these settings can affect remote sessions differently. Also, you might want to look into updating or tweaking the Remote Boost software settings related to session timeout or performance modes—there could be an option to keep the GPU active even when idle. Have you considered using a lightweight script or tool to simulate periodic input (like a mouse move) on the sender machine to keep the session "awake" without manual intervention? Hope this helps or at least gives some ideas to try! Let me know if you find a solution.

Thanks for the detailed description! It does sound like the remote session is going into a low-power or idle mode, which can affect FPS on the receiver side. Checking power management or display timeout settings on the sender machine is a good first step, as sometimes the GPU or network gets throttled during inactivity.

You might also explore tweaking the Remote Boost software settings, especially options related to session timeout or performance modes. Some users even use lightweight scripts to simulate periodic input (like moving the mouse slightly) to keep the session “awake” without manual intervention.

On a similar note, if you’re looking for small decision-making tools or ways to test setups in a fun way, you might find Heads and Tails handy—it’s a virtual coin flip tool that can be useful for quick random decisions during testing or debugging workflows.

Hope this gives some ideas! Let me know what works best for you.
