OBS 28 Drops FPS as soon as you open (Not recording or streaming)

Hey, I'm trying to help a friend of mine out. Since the update to OBS 28 He can be playing warzone 120-150 FPS as soon as you OPEN OBS 28. Frames drop down to 30-50. Without streaming or recording buffer is not even on. when he starts streaming, they go below 30.
The CPU, GPU and memory all have room none of them are over 75% usage. As soon as you close OBS it goes right back up to 120-150 FPS.

Coming up on a loss on why its dropping even before anything is turned on program is just opened.

Same problem here. OBS Studio cuts FPS by a significant amount just for being open. Happens with any game, at any resolution, different OBS settings, with HDR or SDR, it doesn't matter.
Any help will be extremely appreciated.

I realy appreciate the help. I think the problem's not with the settings, since OBS Studio was working fine in my system before updating to 28.x.x. Now, the program seems to be behaving as if it was recording/transmiting while sitting idle in the background but, with way worse performance lost than before.
Anyways's, here's a clean LOG
Again, thank you for the help

Hopefully you realize that OBS is busy once you turn it on, especially if you are on a OBS Scene with video to be real-time processed.
Whether recording or streaming is secondary to irrelevant. Depending on your setup, there is lots for OBS to do to simply generate the preview screen. Running Studio Mode, then potentially 2X the work. The extra work to stream is typically negligible CPU load to handle network traffic (but it depends). The system load starts with having video in OBS' window..
v28 has many differences, so that encoding or other settings may have more or less system impact than before. Or using some new audio features which are CPU intensive? it depends.. I would not be surprised if someone's prior OBS optimizations/tweaks need to be revisited and confirmed or adjusted for v28

I found a the root of the problem with my setup: Nvidia Broadcast.
Killing Nvidia Broadcast processes and reseting OBS to don't use any Nvidia Broadcast related features fixed the performance drops I was experiencing.
I'm on 28.0.2 now and performance is just like before 28.0 update.
I'm aware this is just a "workaround" and not a fix proper but, it allows me to continue to use OBS Studio and that's all I care atm.

Thanks for the tips

Let me quickly clarify the main problem was the camera. Using Nvidia Broadcast camera in OBS killed my setup's performance, not so much the audio features.
