Can somebody enlighten me with that? Right now I'm checking it the total memory used is 900mb and it's on 60%. Is it right?

OS: Windows 8.1
RAM : 4gb(3.6 usable)
 


I'm just using the windows task manager. I could feel lags and freezes when the memory consumed reaches more than 1gb. I was expecting that it could reach up to 2gb and more before i can feel freezes because I have a 4gb memory. Maybe it's just the way it is? Sorry for my ignorance.
