FPS Drops in games as soon as I start OBS

[bravoleader80]

Hello everyone.
It has been suggested to me to open my own thread for this issue which has been reported by multiple people. Let's say I'm playing star citizen. I have 110FPS. As soon as I OPEN OBS studio, just open, withouth starting the stream, the FPS in game drop to 60-ish.
I have 2 monitors, one at 165hz (2k) and one at 60hz(fullHD).
AMD Ryzen 5900X
3080Ti
64Gb Ram Corsair Vengeanca 1600Mhz
Nvenc new as codec, 6000kb bitrate (but I dont have skipped frames during the stream so it is cool)
All watercooled with custom loop so no thermal throttling.
I'm currently on Windows11 but this was happening on Windows10 as well.

I've tried the following
1) Using only one monitor by disconnecting the other (somewhere I read that OBS does not like having different monitors with different refresh rates)
2) Disabling the preview
3) Moving the section with the volumes on the main screen
4) Moving OBS in the main screen
5) Moving ANY screen with a player in the main screen
6) Setting the executable of the game with the flag on "dont optimize for fullscreen"
7) Reducing the amount of web widgets
8) Disabled nvidia shadowplay
9) Disabled Game mode in Windows

I think I have disabled and done more tests but none of this has worked. As soon as OBS starts the game suffers a huge FPS loss.
I'm attaching the log file which I had analysed by the system but I did not get any real suggestion. Ihave seen this issue reported by a lot of people but no solution has been found as far as I know.

You're using SE.live plugin. Please contact them for support.
Alternatively, uninstall it. Then uninstall and reinstall OBS in order to fix the changes made by this plugin. Now please do a test stream/recording of more than 30 seconds and post the log file here.

It was exactly the same even without the SE.live plugin. It did not change anything. I still had the same behavior.
In terms of the log, I streamed for 3 hours tonight, why isnt the log giving you all the information from the stream? why having only 30 seconds worth of log when you have 3 hours?

This is definitely an OBS issue not an SE.Live issue. I had a perfectly solid stream yesterday evening and then while I am streaming right now, my frames have dropped tremendously. Stop blaming other companies and fix your shit!

 

[bravoleader80]

I've removed SE.live and rerun a quick stream of 60 seconds, still the same issue of course and the analyser told me the same thing: "nothing to see here mate".
As soon as OBS starts the drop in FPS happens and I can't understand why. As I said, I tried multiple solutions that were suggested here with no luck. I'm looking for someone competent that could give me a hand. Thanks

Not sure what happened.
It should be uninstalled now. after 30 seconds of streaming this is the result.
The problem is still there. drop in circa 30/40 FPS as soon as OBS starts. Can we skip now the "OMG it was SE.live" and try and focus on the problem please? I just want to find a solution but I need an open mentality here. Blaming the first plugin you see it is not going to help especially because this issue happens with a vanilla OBS as much as an OBS with plugins. Thanks for any real help here.

So now you should have everything you need. Is there a solution to the problem @PaiSand ?

 

[bravoleader80]

Just to add to the list of things I tried, I have a full format of the system. Nothing has changed.
Is it possible the problem is related to the scenes?
Is it better to have hardware acceleration flagged for media sources?

 

[BK-Morpheus]

I suggest, that you create a new, empty scene collection to pin point the source that is producing the problem.
In that empty scene collection you can then create a scene with game capture or what ever and see which source is the culprit.

Thanks a lot Morpheus.
Should I be concerned by the 36 memory leaks from the 3 hours stream? is it something that I should take care of?

 

[bravoleader80]

And another question would be about the HW acceleration on those media. better to tick that yes or no?
