Lately I was trying to record some gameplay from my laptop using MSI afterburner. The game was old and was easily hitting 100+ FPS, so I recorded with x264vfw with fast settings at 90FPS.
The game dropped to around 60-70fps, and the CPU almost immediately hit 100°C and throttled to like half the clock than normal. Is this normal? The CPU in question is i7 12650H, normal clocks are around 4.2GHz, at worst case during recording it dipped to 2.7GHz.
What can I do to improve this?
Laptops just normally run hot. You can try and change thermal pads and thermal paste. Besides that not sure what more you can do.
That and a usb-powered cooling pad for extra airflow
Make use of it if you don’t want to reduce quality.
Is it possible to force hardware encoding? Maybe change the format to h265, I’m no expert but that might free some load from the cpu to the gpu.
In addition to what others have said, make sure the vents are not full of dust or obstructed.
