Hi, I started having this issue approximately last month, where suddenly my second monitor starts working at low fps when I'm gaming and having OBS open. It happens even without starting to record or stream, and when I minimize the game it fixes until I open it again.
The last change I can imagine I made to my computer and OBS is installing the plugin Source Record, but I uninstalled it and cleaned my sources and it didn't resolve the issue.
I had this issue previously, where I play a game and the video I have on my second monitor starts stuttering, and the fix in that moment was to disable my browser hardware acceleration, but I tried that fix and it didn't work, also I can game and have videos with no problem, the problem starts when there's OBS on the background.
This stutter becomes an issue especially with my facecam (I use droidcam), it gets all laggy, even if I drag it to my main monitor, once I click on the game it starts struggling.
My specs:
Windows 10 64 bit
1650 super
i9 9900k
64gb ram in 4 sticks 3200mhz
1HDD with plenty of space left
1 SSD m.2 with plenty of space where I have the OS and OBS.
Focusrite 4i4 3rd gen (DAC).
No cooling problems, CPU doesn't exceeds 60°C when recording and GPU doesn't exceed 65°C (CPU 30% Use when recording and GPU 100%).
Corsair hx1000i PSU (almost new, I installed it 2 months ago).
1 1440p 144hz Monitor (My main).
1 1080p 60hz Monitor (My second monitor).
I use my phone as facecam with Droidcam.
I'll list all the fixes (I remember) I tried:
Capping game fps at 60, even with rivatuner, and also capping my 144hz monitor to 120hz, and 60hz.
Trying different stream and recording configurations (I'll link a photo with the config I use and had no problems until now)
Putting game in 1080p, fullscreen, borderles fullscreen, enabling V-Sync.
Disabling Freesync from my monitor.
Disabling hardware acceleration from my browser, and discord, and wallpaper engine, and almost any application on my pc that has that option and is running in the background, also tried enabling and disabling GPU scheduling on windows.
Disabled Windows Game mode.
Disabled Nvidia game overlay, also xbox game overlay.
Updated GPU drivers, updated monitor firmware.
Tried x264 and NVENC h.264.
Tried multiple games, GPU intensive and CPU intensive.
My OBS config:
Output Base: 2560x1440
Output (Scaled): 1920x1080
Downscale filter: Bicubic (Sharpened scaling, 16 samples)

Well, that's as far as I researched and remember, I don't know how to fix this, and it's strange because I didn't had this issue before, I streamed even more demanding games than the ones that I had this issue with and didn't had this problem (I tend to stream the games on 1080p windowed, obviously a 1650 super isn't enough for the workforce), so any idea on how to troubleshoot this is welcomed, thanks!
