A year ago I wrote a SDK on PS4 DevKit, and when I looked at the spec I was like "Wow 8GB RAM, that's a lot to play with".
But then the OS takes about 4GB, and we have some huge textures (0.5GB) , and pretty dense point clouds (some more RAM, ka-ching!), need to leave some memory for the application on top of the SDK...we ended up having about 0.5GB for ourselves.
I was really bummed out, and this feeling is pretty much identical to the one I have when I see my total income, and then what's actually left after taxes and all the other shit.
