Stutter while trying to play emulators

[rizefall]

Hey,

Recently i wanted to do a playthrough of some Sonic games. As i was trying to use different emulators, i started noticing how the game stutters whenever my streaming program is open. It doesn't matter if it's Streamlabs or OBS, as soon as the program is open, almost every emulator seems to stutter.

Depending on the emulator it's only for the viewer (Preview, streaming, recording) or both me and the viewer. High end games i can stream without issue so i dont know what's going on.

This issue is only related to emulators, not games like Cyberpunk, Sonic Mania (non emulated), RDR2 or the like.

Streamable links showing the stutter:

- I have a Nvidia 3080 GPU, and a Ryzen 9 5900x CPU.
- I tried lowering the Hz on the monitor
- Even disconnected my second monitor
- No difference between Game or Window capture
- Reinstalled video drivers
- Game mode is off, so is Xbox Bar or wtf it's called
- No GPU hardware acceleration
- Tried running as admin

Do any of you know what i could try and do to fix it? I'm at a loss.

Streamlabs support, how ever serious we should take them, said this: "Personally I haven't heard of this happening before, but I do see you're getting some lagged frames in your diagnostic report, which means your GPU is being overloaded." and they gave me some thing i could try to fix it. I listed it above, but I'll provide a screenshoot:https://i.imgur.com/uISNVYN.png

Same issue in OBS and Streamlabs.

Your emulator has 100% constantly frames?
Create new profile with only one source.
Can you select time with stutter moments?

I managed to fix it, after trying for 5 days and shortly after making this thread.

The OBS Log file did note i had a GPU overload, and after looking at the task manager it seemed like some software i was using spiked in GPU usage for some reason.

Turns out it was a program called "Xsplit Vcam" that was the issue. It's a webcam program that helps with background removal (among other things) similar to Nvidia broadcast.

When i checked the performance tab, it turns out Hardware Acceleration was on, and it wanted to use my GPU to run the whole thing instead of the CPU. Changed it to my CPU and the problem is solved. My only guess is that an update changed it around for some reason, as i've had this software close to a year and never had issues before.
