Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi, I have an MacBook Pro 16" 2019. The GPU is a Radeon Pro 5300M with 4GB of GDDR6 memory. When I run iStatMenu I see, that the memory is almost at 100 % all the time, even when I am just using Safari. I am however connected to an external display, can that be the reason, and of not;
Is macOS not clearing the GPU memory or why is memory usage always so high?

I would not worry about this unless you see a problem with performance.
macOS tries to optimize the use of RAM - and, I presume, VRAM.
It may be keeping stuff in VRAM after use for, well.. reuse if the case happens.
Just so long as the VRAM is released for other use when needed, it is fine.

If the GPU itself isn't running at 100%, there is nothing to be worried about.
Other than that needed for display, the rest of RAM likely doesn't get
released until something else comes along and needs it.
