Question / Help Can't Stream Overwatch without rendering lag/stalls

[anyma]

Hi guys, thanks in advance to all those who will try to help me.
I would like to stream overwatch at 720p 60fps, but I'm having a lot of trouble. I have a laptop ROG G750JZA (i7 4710HQ and GTX 880M, double SSD in RAID 0 and RAM 16GB).

The laptop is a few years old, but using shadowplay I can record smoothly and without any problem at 1080p 60fps.
With OBS I have lag problems (only in streaming, not ingame) even at 540p 30fps.

During streaming Shadowplay disabled and Win10 game DVR disabled. G-Sync active in Overwatch Settings.

Is it possible that I can not stream at any resolution? even if I have no problems with shadowplay? Is there so much difference or am I doing something wrong?

Last log in attachment with some try.

Thanks again in advance !!

Ah, internet is not a problem, I have 50mbit/s in upload and 300mbit/s in download

We do not provide support for streamlabs' version of obs.

oh, I'm sorry, I did not know :) I tested with normal obs at 720p 60fps but the results are identical, I attached the obs log.

As opposed to Shadowplay, OBS needs to composition and render your scene (inlucding resizing, filtering, sharpening etc.) and access your frame buffer through windows (OBS can directly access it on the video card).
The rendering is all done by the GPU, even if you encode with the CPU.

So you need to make sure, the GPU has some power left for this job and the only reliable way to do so is by limiting your ingame fps (either through ingame settings, tools or with vsync) and reduce ingame details, until the GPU load never exceeds ~95%.
You also use the leas performant capture method (monitor capture) instead of game capture.

thank you for the answer, I'm already limiting the fps with the v-sync. So I have to decrease the graphics settings of the game ... ok I'll do it!
At least now I'm sure it does not depend on any problem in the obs settings.

should not the game capture weigh less on the graphics card? Provided to limit the fps (as you said, for example with the v-sync)

last question: when you talk about monitoring the GPU that does not exceed 95%, do you mean with or without active obs?
