Losing my mind trying to figure out why OBS is choking.

So, I'm trying to stream Star Citizen.
I've done it in the past with a 1080Ti and a much weaker CPU (5820K)
I'm on a 3950X+3090 now and it's choking...
Provided screenshot, and logs.
https://obsproject.com/logs/qLKU9tAVrjEDcVds <- This was from a fresh portable installation with no plugins and nothing in there except game capture in the single scene.
These are from my actual installation (also portable)

A few people in the Discord tried to help me, to no avail.
The suspicion was that it was the plugins.
It's not.

Help?

You could be using nvenc instead of x264 encoder.

The log contains an Auto-Config Wizard run. Results of this analysis are therefore inaccurate. Please post a link to a clean log file.
To make a clean log file, please follow these steps:

1) Restart OBS.
2) Start your stream/recording for about 30 seconds. Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.
3) Stop your stream/recording.
4) Select Help > Log Files > Upload Current Log File. Send that link via this troubleshooting tool or whichever support chat you are using.

So we managed to narrow it down a little bit.
If I turn off my preview, it's completely fixed, no lags no choking.
Any ideas?

If you are using OBS in "Studio mode", then you are giving OBS (and your computer) 2X the rendering to do... Preview and Live view

Have you seen the insane amount of plugins you have?
In OBS for streaming and recording the less the better. The more things you add, the more resources you use and the worst it performs.

Remove everything but the plugins you really use. And if those are too much, commit to a more simple layout and remove the ones you use on a single thing.
Videos, mov files (in my experience) consume more reources. It's better to remux them into webm (transparency allowed). Also, have to be the same fps as the stream/recording. Audios are the same thing. Anything with transparency uses more resources. Filters are exactly the same on consuming resources. Is not about how much RAM you have but how much use of CPU/GPU time (bottleneck). The idea is to give OBS less to work on for best quality.

Always check the Analizer:

Analyzer | OBS

OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.
obsproject.com obsproject.com

And finally, windows 11 isn't a safe production enviroment, yet. At least for streaming/recording. If you can go back to latest version of Win10 you'll fix a lot of small issues.

Thanks for the replies guys!
So, I'm not using it in studio mode. So there's that.
I thought it could be the plugins, but it's not because I tested it with a fresh install of OBS with no plugins in it.
It only had one scene with the one game capture source.
I do usually convert everything to .webm, I missed a couple this time I guess. WIll fix that.
Don't think it'll help though, because of this test. It had NOTHING on there and still choked.
