oh! it changes differently bc some of it or all of it is compressed. app says 4GB. process memory says 1GB or so. so I just need more memory so as not to compress vram. vram should never be compromised as needs maximum speed.Michael

sure. my app uses 20-25GB memory according to activity monitor. In the app itself, it says im using 4GB "vram". so the 20-25GB in activity includes 4GB of "vram" then? some people from apple said vram is allocated different then what's shown in activity monitor, but I don't think that is true, because its unified now.Timothy Liu

Hello. I am wondering how M1 max uses Vram in the new unified system? My app says im using 4GB vram on M1. When I adjust settings memory usage changes on activity monitor but not at the same rate as what my app is telling is vram usage?? Wondering what your thoughts/experiences are with vram usage on the new M1 max? Thanks.Timothy Liu
