Q: Macpro 10.10 lag

I have a MacBook Pro 2010, 2.53 Ghz i5, 4GB memory 1067MHz DDR3, running on OS X Yosemite.

I use to use this computer for school work and computer game, as recently(pretty much as soon as i upgraded to 10.9.5), my computer has been lagging a lot when I play games (DoTa for example), and those game worked perfectly fine before. I don't really know much about computer but I really wish to have this problem solved.

 

Thanks

MacBook Pro, OS X Yosemite (10.10)

    From where did you get them? Macs a picky about memory and unless the seller says they will work in your model Mac they may not work.

    i got them on http://www.macsales.com/memory, where "The hatter" told me to go. On the website it says it works with MacPro.. So i assume it would work..

    Mavericks and Yosemite use memory differently than previous versions of Mac OS X. Now, all possible memory will appear to be used up, and that is completely normal.

     

    There is no inherent benefit to having memory be available but unused, and these new versions have new ways to use it all, yet make it INSTANTLY available if an Application asks for more. That memory scrubber program you downloaded will do nothing useful for you under Mavericks or Yosemite.

     

    To see how your Memory situation is doing now, you use the new version of Activity Monitor, and look at the memory pane. Use this link:

    interesting you point that out, because as I was trying to play game, I also used the "Memory Clean" app while in game. And even though it shows that I have about 1.3 GB unused after it cleans, but the game actually lags more...

    I have installed the new memory, which is 8 GB, and the first game I played went very well no lag at all. But the second game started to lag a lot again. Turns out my memory was still slowly drained to have very little avaliable. Is there a virus or something? because why is my memory keeps being drained...?

    With the memory drained run EtreCheck again.

    Also, go to the game developer's support site. May a problem with the game not managing memory correctly.

    I check mutiple times, it is the File Cache draining my memory. While in game, file cache can sometimes go up to using over 3 GB, I really wish to know what is File Cache and how to fix this? I did the Repair Disk Permissions thing, but it didn't help at all. Is the File Cache thing created by game or where did it come from?

     

    Please help and thanks...

    File cache consists of files you have read recently. They are kept in their own section, in case they are needed again soon. If you need more RAM for ANYTHING else, they are dumped in an instant and used for the requested RAM. That is not the source of your slowdowns.

     

    Mavericks and Yosemite will appear to use all the RAM available and then some. But in addition to being able to dump File cache to gain more RAM, they also begin to use Compressed RAM. This effectively gives you an even larger area to work in, as if you had more that your physical RAM before you even dip into Virtual Memory.

     

    That is why it is essential to Read the "Memory Pressure" graph to find out where you stand. If its green, you have no memory problems, despite the appearance of memory being full.
