I followed the instruction to upload log here:
Previous log:
Current log (after record 30s):

The issue is just added the "display capture" and immediately the Windows performance lag.
The status is back to normal if "display capture" unchecked (eye grey out) or removed.

Windows 21H2, update the latest patches.
Driver for DELL XPS 9570 with the latest driver from DELL, and latest driver for Nvidia Gerforce GTX 1050

With the spects you have you probably can't do 1080p and 60fps. Try at 30fps or scale to 720p 60fps
If you overclocked the CPU and/or the GPU, undo it.

Please restart Windows (not turn off and on, restart) and perform a test stream/recording for more than 30 seconds doing as you normally do, including playing games, full camera or whatever you normally do.

This is the current log: https://obsproject.com/logs/C6Z4Nv-JkAAdk2eB after set 30fps, HD (not full HD as previously) and Windows restarted.

I don't think the laptop spec have the issue as before it worked so well until the Windows re-install (I changed the SSD 1Tb > 2Tb, same Samsung 970Evo Plus)

Whenever OBS start the Windows performance immediately lag, especially the mouse moves. Do you think it is a bug?
The above link analyzed the GPU encoder overload 4.1%.
I dont have anything for overclocked CPU/GPU.

Base resolution is the resolution of your monitor. If your monitor is 1080p, set it as 1080p, if it's 720p, set it to 720p
Output resolution is the resolution you aim to stream/record. Here you set 720p or whatever you like.
Run OBS as admin.
Make sure you have the GPU driver updated. Same for the other drivers.

What do you mean with windows lagging?
Check the RAM.

Thanks.

My screen support 1080, so It sets 1080. RAM 32Gb
I am following up OBS Wiki: https://obsproject.com/wiki/Laptop-Troubleshooting
This is exactly what I am facing right now but it does not help much after adding to Graphic Settings.

I tried to uninstall OBS 28.03 and re-install both v28.01 and v27.0, but both of them same issue, the performance with multi-GPU system,
as informed, I already installed the latest driver of Nvidia and all but DELL.COM

Windows lagging = performance issue, the mouse moving is jerky...
This can be very frustrating

I resolved the issue, so I would like to report it. Please double-check if the newer OBS version can fix or not.

Agree that Windows can set graphic mode in:
- Power Saving
- High Performance

In "Graphic Settings" (Windows search, type: Graphic Settings), add the OSB64.exe to Graphics Performance Preference.
even I set high performance in Windows seems conflict between 2 modes "saving" & "high performance".

I decided to disable completely the integrated card by Start > Run type: devmgmt.msc
Go to the display adapter to disable Intel UHD Graphic 630.
Force windows to choose Nvidia Geforce 1050.

I would like to suggest OBS auto-identify and decide the high performance in case of multi GPU.
Or
OBS allows the user can select or know which GPU using.

Updated.

If the integrated card was disabled so the brightest of screen impossible to adjust.
So I reverted by disable the Nvidia, enable integrated card
