How to check how much "free" iGPU VRAM the system have in MB? How to check how much free iGPU VRAM the system have?
I thought it was a simple easy task, but so far I don't find any useful result by googling.
I knew how much VRAM I have. I knew I could run system_profiler SPDisplaysDataTyp at cml. I knew I could check GPU % of each application in Activity Monitor &gt; % GPU Column. I knew there is Activity Monitor &gt; Window &gt; GPU History Window etc..
But none of them tell me how much iGPU VRAM the system uses and how much free VRAM is in MB value.
Do anyone know how to check the info?
CML way is preferred.
if not, Built-in tool is preferred.
if not, Open source tool is preferred.
if not, Free tool is prefered.
Thank you very much.
Edited: I don't want to use a paid app for this purpose.
You can check this using the iStats Menu program, which is a paid app that you can try for free for 14 days:

Note that you'll probably find that the VRAM is maxed out, and there's much you can really use this metric for unless you happen to be a developer actively developing your own software using the GPU. In that case, you should use the free Instruments tool from Apple instead.
