Bug Report OBS uses too much GPU (Nvidia)

[Bleuzen]

Hi, when I open OBS, my GPU usage goes from 0% to about 25%. This is already when not recording, just by opening up OBS.

Here is a screenshot without OBS. My GPU usage is at 0%:

Here with OBS (1080p60 settings, but not recording):

I found out, that it takes less GPU when using a lower resolution / fps. Here with 720p30 settings:

Again: The screenshots are taken when OBS was NOT recording.

I tryed to disable the preview, but then my GPU usage (with 1080p60 settings) goes from about 25% to about 15%. This is still much.

I know, OBS does need some GPU, but not that much!
On Windows it takes about 2%, not more. On Linux 25%. This is a big difference, which costs me some FPS in games.


My system:
CPU: i7-7700
GPU: GTX 1060
OS: Manjaro Linux KDE
Kernel: 4.14

What are the clock speeds at? 25% load when the card hasn't clocked up (i.e. not enough load to trigger the speed increase) isn't abnormal.

My clock speeds:
Without OBS: 873 Mhz
When OBS is open: 1569 Mhz
In games / max.: 1923 Mhz

I did the UNINGINE Superposition Benchmark. Yep, there is realy a difference. OBS is using that much GPU.
without OBS: 43 FPS
with OBS open (not recording): 34 FPS

Is the topic dead now?

"When OBS is open: 1569 Mhz" is your CPU speed? I had an issue with my Dell E6430 laptop the energy saving scheme in Debian 9.2 locked its 3ghz i7 to 1600Mhz changing the scheme and the CPU went full tilt.

No, this is my GPU speed.

Dead again?
Has still someone an idea why this happens?

Problem still exists..
And I can't report it on Mantis, because Login there seems broken.
