I’m not sure. I’m a photographer and comic. I switched to mint cause it’s easy, I’m not much of a computer person.

Why do you care?

If I had to guess, VRAM is probably holding stuff as a cache.

VRAM doesn’t use a lot of power and as long as you aren’t seeing out of memory issues, it doesn’t really matter.

400MB??? What do you have running? I never use more than 100 unless I open a game or something.
