Question / Help OBS Closed = ~300FPS, OBS Opened = ~100FPS?

[Christopher Baker]

Hi Guys,

Something unusual has just started; for over 6 month I've been using 2 computer setup using the commonly known;

On the first computer using OBS Projector to Screen 3 and then Captured by the second computer and encoded on the second computer and pushed to Twitch.

For 6 month this hasn't been an issue at all until sometime last week I noticed that my CS:GO isn't getting more than about 110FPS. We haven't changed anything configuration wise, we have adjusted a few scenes but nothing that I could think would affect this.

Some things I know that may effect but hasn't so far;

GTX 980 -> Primary Gaming Screen (Running at @ 144Hz)
Onboard Intel 4600 -> Secondary Screen for OBS & Watching Twitch Chat + Third Screen for Projection Screen (Captured by another PC to stream) (Both @ 60Hz)

I'm looking to do a reinstall of everything because it's really killing me to play games but before I do I wonder if anyone can see anything in my logfile that's obvious to cause? I have tried an OBS reinstall (OBS-Studio-19.0.3-Full-Installer.exe) which didnt do anything.

Logfile -> https://gist.github.com/anonymous/7cd8d06ef15d7d2b5ace2a30476ebc8b

You should plug all your monitors into the actual GPU. Splitting displays between two graphics adapters is an absolute nightmare for capture.

Without a full log that contains a stream/recording attempt in it, hard to say what else could be going on.

Not actually encoding on the gaming PC? The encodings all done on the secondary computer that's captured the projector screen on the gaming PC. All OBS does on the gaming PC is capture and project to monitor 3 for the streaming PC to capture the screen and do all the encoding on another computer...

Why are your scenes so incredibly complex on the gaming PC then? You should be running all of that off the streaming PC.

Gaming PC should only have a single game capture source in it. That's why I assumed that you were having issues with the STREAMING PC, because having all those sources on the gaming PC is just crazy backwards.
