question Prevent performance loss on Server when RDP is disconnected

[FliP0x]

I'm having a weird use-case (don't ask) in which I am running a Game on a remote Windows Server 2019 host.

 

When I am connected over RDP it runs and performs fine, but as soon as I minimize the RDP Window or close the RDP connection, the Game suffers a huge performance hit and runs choppy.

 

The hosts power plan is set to High Performance, Sleep and Idling is set to Never occur, but I can't find a way to circumvent the performance hit when no remote display is connected.

 

Is there a way to prevent the host from throttling performance while no virtual display is connected? 

 

EDIT:

The performance loss seems to be caused by the game, rather than the Windows Server. I tried settings priority to realtime and other tweaks within Windows, but nothing helped. The game itself doesn't have a "power saving mode" that I could disable. When I disconnect the RDP, it considers the game as minimized and therefore the game throttles performance while minimized.

Physically plugging a dummy display plug to the GPU should help in this situation.

That would work, but I don't have physical access to the machine.

 

If there is a solution, it would have to be software.

Don't think that exists...

Thanks for the input.

 

It was due to the software, nothing a windows setting could have done.

 

A workaround was to have a Android Smartphone connected to the host to keep the performance.
