Spout slows FPS

[thunderingjack]

Hello, I'm using Resolume on a i9 PC with a RTX 3090 GPU.
Whenever spout is enabled my FPS slow to almost half?
Composition is set 1920x1080 @60
3 outputs - 2x 4k60, 1x 1080p60 (GUI), This normally works with little effort.
At a bare minimum, I can open a new blank composition, output disabled, runs at 60FPS.
I switch on Composition Spout output and the FPS drops to high 30-40's?
Any ideas?
Thanks,
Stuart

Could you please send us the Resolume log file via the feedback tab in preferences?
Thanks!

Hello, I've just upload thru the feedback portion on Arena. It happens every time I load Arena unless I use the 3rd party Spout setting app and reload.

Is your spout receiver running on the same GPU as Arena?
What do you change in the Spout settings app?

Hey Zoltan,
I can confirm the GPU render is coming from the RTX 3080.


Here are my Spoutsettings -

Increasing the buffer could help a bit.
Which app are you sending to?

Hello, did this ever get fixed? Im on another new PC win 11, same problem. RTX3080.

According to Spout Demo Receiver - Arena is using DirectX 9?
This is very problematic on big shows.
Am I missing something here?
Thx

You can change DX settings in the spout settings in your file browser

Hello Avrol,
Are you referring to the SpoutSettings.ini file?
Thx,

There should be a spout settings app with a small GUI.
