OBS rendering lag even WITHOUT streaming/recording

I've had this problem for about a week & it's driving me crazy. I know there are already other posts like this, many of which I've already seen & tried, but none of them really helped...;;

Issue:
The FPS drops abysmally low & it's not a one-off thing like what happens sometimes when there's a big activity spike; it keeps happening constantly, to the point that streams look like Powerpoint slideshows & are just unwatchable.
But the thing is, I know it's not even a network/connection/internet issue cuz it happens even when I'm not streaming? I can literally just open OBS and it would be lagging. All other programs are fine, it's only OBS specifically.

Possible triggers?
I did an in-place Windows upgrade and enabled SVM in BIOS, possibly a Windows update as well.
The problem started happening 2 days after that, on a Marvel Rivals stream which was the first stream of the week.

Things I tried:
  1. Clearing DirectX shader cache; friend thought it might be caused by Marvel Rivals​
  2. Updating & downgrading OBS (currently using 30.2.3, tried latest, 31.0.0, 30.2.2, and 30.2.0; can't do latest cuz it messes with Riot games)​
  3. Enabling/Disabling HAGS​
  4. Setting OBS as high performance in graphics performance preference​
  5. Using DDU to do a fresh install of GPU drivers​
  6. Updating & downgrading GPU drivers (currently using 572.16)​
  7. Running OBS as admin​
  8. Disabling Windows game mode​
  9. Disabling fullscreen optimization for OBS​
  10. Setting energy mode for OBS to maximum performance in NVIDIA control panel​
  11. New fresh scene collection​
  12. Cleaning up browser/text/media sources​
  14. Renaming the obs-studio folder in AppData/Roaming​
  15. Running OBS in a different Windows user account​
  16. Running OBS in safe mode with no plugins, websockets, etc.​
  18. Uninstalling OBS & doing a fresh install​
  20. Changing monitor refresh rates​
  21. Making sure Windows & OBS audio sample rates match​
  22. Setting OBS process priority to high​

TLDR:
  • It's not scenes/sources; I tried a fresh scene collection & OBS reinstall
  • It's not plugins; I tried safe mode
  • It's not encoder/fps settings etc; it happens even when not streaming/recording, and I've used these same settings for a long time with no issue
  • It's not hardware; motherboard is new, everything else is working fine
  • It's not internet; network & connection are fine

Specs:
• OBS ver 30.2.3
• Mobo - Gigabyte B550M DS3H AC
• CPU - AMD Ryzen 7 3700X
• GPU - NVIDIA GeForce RTX 3060
• PSU - Seasonic Prime PX 850W Platinum
• RAM - 32GB Kingston HyperX

To add to this, there could be random times where it stays stable for a while, maybe a few mins to an hour or so, before it starts lagging again.
Currently it doesn't seem reliable as it lulls me into a false sense of security lol,,

Crap SE plugin installed & most of the remaining plugins are stale. The installed NDI runtime is from like 3 years ago. Plugins need to be maintained.

I would update all plugins as needed.

Rendering lag is GPU overload, plain & simple. If it remains after taking care of the plugins, start reducing load. Drop both monitors to 60HZ.

Start a clean slate, drop all the BS for testing. Create a New Scene Collection with just (1) Scene/Source.

SE was actually the first thing I tried to remove, and then booted in safe mode to see if it was any of the other plugins. It still lagged.
I tried updating plugins but most of them are already the latest versions.

I checked, and my GPU is hardly even being overloaded, especially since it lags when I'm not even playing any games or doing anything. Even if I was, other games or programs run smooth as butter, it's only specifically OBS that lags.
HWiNFO64 says average GPU utilization is 14%.

I already mentioned trying all of those suggestions in my list, unfortunately none of them work.

I'm running the same version of OBS with no issues. So either your set-up is bugged or your rig is broken. I gave you the first steps I would take. You do you.

The symptoms you describe might indicate sudden performance loss. This can happen due to overheating, so the hardware throttles, so for a second there is just a fraction of the expected performance. Overheating could be CPU or GPU. Make sure all fans are working properly and check CPU and GPU temperature during such a lag with appropriate monitoring tools.

Yeah I've been checking temp and utilization, it's always just around or below 50C, and 40%...OBS says it's being overloaded, but the CPU/GPU stats say otherwise. T_T It just doesn't make sense...
