I have a 27 imac i7 3.4 with 2 tb and 256 ssd. When i play starcraft 2 and i minimize it or have it in the back ground. The computer lags to type and everything I don't believe this is suppose to be happening. This is very annoying and on my 2009 iMac I didn't have this issue at all what could be the problem. BEcause this is def. something that should be happening at all.

its showing starcraft 2 at like 35% to like 42% usage. Why is that high and on my old 2.8 iMac i7 it never slowed down at all when i typed or lagged. How is it that just by having this game open and minimized its slowing my computer that much. Cant a SSD support that with no lag with no problems?

What about the RAM usage?

Are you sure that's how much you're using or how much you free? By the way, how much ram do you have installed?


Its showing the ram being used by this program. I have currently 8GB.

Probably not much at all. I have 16 gig in my iMac, and I barely use six gig of it. It all depends on your usage of the computer and how your page outs look.

To determine if you can benefit from more RAM, launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.

It shows like 7.90 GB used So i think this would benefit me to upgrade the memory.

WHen i rebooted its showing like less then 5gb used. And pages out is zero right now. But when i open say a program like sc2 in the background when i go to type or do anything my computer is laggy but when I close the program its fine. What could be the cause of this?
