Lower CPU and GPU usage on second screen

Hi everybody,

When running my game in debug layout on my laptop, CPU usage is around 32% and GPU is at 18%.

If I drag the debug layout window to my second screen(VGA)connected through a usb-c to VGA, CPU usage drops right away to 21% and GPU to 6%.

I am a beginner, can anybody help me understand the huge difference between both screens?

thanks!

My first thought would be that they have different resolution/refresh rates.

if your laptop has dual graphics options, it's possible that the integrated chip is solely running your internal screen and that your dedicated chip is either running or assisting in running your monitor connected via USB-C. As this would be a more powerful GPU you would see a drop in usage.
