I often use large comps with big textures in Adobe After Effects, and that eats up all 16GB of VRAM no problem, so I know it’s there to be used, but the problem comes when I need AFX to use the GPU but it’s locked up in other apps where I can’t easily distinguish which one is using it. It’s almost as if it simply keeps things buffered as long as it thinks it needs it, which makes sense. So it seems the VRAM is released or flushed as the display is off but still remains low when using programs again. Try purging this memory and all your programs will stall until the inactive memory is back to around 25 of your total RAM (tested on Mac OS X 10.6 and 10.7).

Michael Kern Ive used MacBooster on Mac OS X for several years and strongly recommend it. Saying that inactive memory can only be good for you is the biggest lie of the Mac world In practice, Apple computers cant work if you dont have a lot of inactive memory. This product found errors and fixed them quickly and gave me the option to free up memory which greatly helped my aging mac function better.

I have a hot corner (MacOS) set to turn the display off, and when I activate it, even just for a few moments, my GPU usage goes down to near zero once it comes back on -> not surprising since it’s off, BUT it continues to stay low as I go back to browsing around Chrome that stayed open, and other programs.Īnd keep in mind I’m pushing the VRAM with about 100 tabs open in Chrome that have many videos ready to play in the tabs. Got this product for my older mac to help speed it up. I have found the answer to actually be 'yes' you can release (flush) the VRAM.
