For me there are programs that "can acceptably use that much RAM" and those that it's "unacceptable", to me. what's 20% to 40% of my gaming rig's resources may be uncomfortably taxing and laggy for my laptop. Its okay to waste resources on my gaming rig but the laptop needs all it can get. I accept some software will not reasonably run on the laptop. My employer has stuck me on 10yo hardware before, running windows 10 pro + intrusive expensive antivirus and nobody is around to question why their computers are getting 5-15fps and locking up for a minute or two when you open chrome. It becomes normal. Any software is the host and/or backbone for other running software should focus on reducing it's own resource usage for the sake of its children.
