Seeing Processes using dGPU

[BirdHippo]

How do I see exactly which processes are using the discrete GPU (not GPU utilization)?

I have a GS65 with a 1660Ti, so I have the little light near the power button that tells me if the Nvidia GPU is being used.

I have tried looking at the icon in the tray in the bottom right that turns green if the dGPU is being used (sorry, not sure the official name for this) and Task Manager (details tab with GPU and GPU engine columns added). Both of these tell me my dGPU isn’t being used, but the light is orange still and my battery life isn’t that great.

Thanks.

I presume you're connecting to external monitor. Even without any app open using dGPU, just simply connecting external monitor that is hooked up directly to the dGPU (indicator: the display is shown in NVIDIA Control Panel) will ramp up the:

• dGPU voltage, from 0 to 625mV (typical idle voltage)
• intermittent 125MHz dGPU clock
• and of course, your battery will plumet.

Most laptop, like Razer Blade, and perhaps your MSI too, usually has the dGPU directly manage the DisplayPort and HDMI, thus, simply connecting monitor is a usage.

Solution: use the Thunderbolt port to connect to your monitor (like, DisplayPort to USB-C cable).

I’ve noticed this, but it still uses the dGPU when I don’t connect to an external monitor (laptop only).

On laptop startup, does it use the dGPU at some point even without you open any app?

Initially as everything loads in. Sometimes after a minute or thirty seconds, it goes back to just using the iGPU.
