Question / Help CPU Performance

[flybel]

So today I wanted to start streaming live to twitch. I tried OBS before, but I downloaded OBS Station today and set it up completely.
But now when I close down all and everything I can without it having an impact on my gaming experience (which means also activating Razer Cortex Game Booster) I get to 5% CPU usage. When I start Rocket League which I took as a test example, I get to 20-30% CPU usage.
But now, when I start OBS, CPU usage gets to 70-100% and makes even training in Rocket League impossible due to 20-25 FPS. This happens no matter what scaled resolution (lowest I tried is 360p; using bilinear), what bitrate (lowest I tried is 256), what encoder (tried all 3 with the highest performance presets they have), what webcam resolution/fps (lowest 240p with 15 fps), no matter if I enable preview or not, if I stream or not.
With preview disabled AND not streaming and not recording, CPU usage is at 80%.

My CPU is Intel i7-4700HQ (2 year old 1000€ gaming notebook). Full specs in attachment file.

Try to load Studio on NVidia GPU: Laptop? Black screen when capturing? Read here first.

You need to reset your stream keywords. Those files you posted have your stream key. Only post obs logs. Can a mod remove that attachment?

Here is what OBS log analyzer said:
Multiple video cards detected

If you are having problems and are using a laptop, see this thread for advice.

If you are using SLI or Crossfire, you may need to disable it for compatibility with OBS.

Slower preset in use

You have changed the default preset to hp. Using slower presets can result in late frames and high CPU usage / low FPS. You should only change the preset if you are sure you have the CPU power to spare.

Wireless detected

You appear to be streaming over a wireless connection. While this can be OK, keep in mind that interference from other radio sources or obstacles can cause your connection to momentarily stall, resulting in dropped frames or disconnects. A wired connection is strongly recommended for a reliable stream.

I didn't read it first because I didn't get a black screen... But I'll do so now, thanks.

I reset it. Sorry about that, just wanted to make sure my scenes are included if anyone wanted to check them for CPU-hungry objects.


I will test further within the next days and update this thread.

No problem.

Okay, so today I streamed Rocket League again without closing down any background process but using my nvidia card for OBSs.
Performance was way better! Thanks for your help!

I didn't try launching OBSs with my nvidia card because I had a black screen on OBS, and now OBS studio seemed to work with the Intel GPU so I thought that shouldn't be the problem...

Problem resolved, thread can be locked.
