The CPU is an i5 11400H (Intel UHD graphics for 11th gen processors)
note that the laptop also has a discrete GPU
reinstalling MSI afterburner does not solve the issue. This issue has been present across 2 OS reinstalls.
this is not happening when the laptop is charging, only while on battery
plugging in the charger immediately speeds it back up again
if the game is ran with the discrete GPU, the issue doesn't seem to be present
this happens in all games, 2D and 3D
this only happens while "Enable hardware control and monitoring" is enabled
I'm guessing this has to do with the hardware polling. There is either something wrong with how it polls the iGPU, or it has to do with it trying to poll the deactivated(?) discrete GPU, I am not sure which.
EDIT I still can't confirm which of the 2 suspects it could be but I heavily suspect the latter. If I open furmark up, in the config menu it tries to display the temperature and TDP of the GPU. The stats for the dGPU are repeatedly appearing and disappearing. As with MSI afterburner, having this open slows the iGPU down massively.
