I have two laptops monitoring the gpu with mission center one laptop uses gpu
like this just using linux no video or anything heavy.
It does increase with video playback.

The other laptop is completely dead no graph or usage at all even playing videos
Little perplexed as why the second laptop isnt showing gpu.
This has been a morning project learning more about Opengl and questions I had about it.
On my lenovo thinkpad T420 intel graphics I have no Gpu usage what so ever local video or web video
Its using it all on Cpu
Since Not a Gpu guru I need a starting point if someone knows what to look at?
It doesnt run half bad this way but it should not be doing this.
From what I can tell opengl and everything (driver) is all loaded just no programs shows Gpu usage.
Going separate it from docking station see if something changes.
My other lenovo laptop working great and proper.
