OBS photoshop lag only when charging laptop. please help!

[Mocchib]

Hello! I hope someone can help me out with this issue...

Everything use to work fine but a few months ago after updating OBS I ran into an issue. When I open OBS and photoshop everything works fine but as soon as I need to plug in the charger photoshop lags. when I close OBS, photoshop works fine even when charging but its when OBS is open and laptop charging that photoshop starts lagging.
Prior to this I use to be able to record smoothly even when laptop was charging. It was just after that update.

I don't know much about OBS and all its settings but I have searched everywhere what I could change to make photoshop smooth so I can draw because drawing with a constant lag is impossible. I was able to make it smoother than before by changing it to x264 and bitrate 2500. Oh and its on display capture.

I just don't know why photoshop stops working smoothly only when OBS is open and charger is plugged to PC.
I can record and use photoshop just fine if charger isn't pugged. Does anyone know why this might be?
Also photoshop is the only program that's affected, I also use another drawing program called SAI and that one is not affected at all, or rest of PC nothing else lags just photoshop.

real-time video rendering is computationally demanding, which is why laptops can be a challenge (as almost always designed for battery life, etc, and not pure performance). Hence, thermal throttling on a laptop far more common than on a desktop system. And mfg and OS vendors don't make it easy to detect

Just curious - what are you doing to monitor thermals on this laptop, and ensuring that you aren't running into a new OS or laptop mfg driver issue being more aggressive with thermal throttling? or a battery degrading over time and is now finally causing more heat when charging, which in turn is causing thermal throttling? Or running some other background workload/process pushing your system into overload territory

As for OBS update, I'd look into 3rd plug-ins which may need updating/replacing due to underlying browser source update in recent OBS update (27.2??)

And though it would be unexpected, the other possibility is that you or ?? changed the default power profile at the OS level and that is impacting performance when plugged in.

Hello! thank you for taking the time to reply,
So I don't know much about lap tops and their technological aspects so I haven't been monitoring the thermals on this lap top (not sure how to).
Prior to the change where photoshop would start to lag in this specific scenario (photoshop on, obs on, laptop charging)
I hadn't changed anything. then when this happened I changed settings on OBS that I found on youtube to help it run smoothly, and it got better but not all the way smooth how it should be, so still hard to draw with the lag.

I will try to look into the things you mentioned and hopefully find something. I really appreciate you! thank you so much!

Hey!! i wanted to thank you again and let you know I was able to to figure out the reason. It was the refresh rate on the monitor. I didn't know a dual screen could make a difference. I put them both on 60 hz and it works now! one was at 120hz and other was at 60hz
