Re: hwo to use more RAM in 9.10
Just Like MasterJS said, Visual Effects most likely is a graphics card thing, though if you either have a graphics card thats not being used to its fullest potential, or just a really crappy card, Visual Effects will take up a lot of the PCs CPU power (at least I have noticed on some PCs).
The weird thing is, I have a Pretty crappy Dell, P4 (2.8GHz) with 512MB ram (I just acquired it) and it runs full compiz fusion without any problem, and theres no freezing of the PC, and it runs at about 50% ram no swap space.
