Because my cache takes 4GB of memory, and I only have 6GB total. I'm already using 1.4GB for open applications, which only leaves me 400 - 900mb of RAM for a heavy graphic video game (I need approximately 2GB at the very minimum). FPS is ridiculously low (frame lag).
How many programs do you have open when you want to play a game or how much memory does the largest consume?
I opened 2 56mb tiff files in Photoshop, 24kb svg in Illustrator, a blank doc in Word 2010, a 2mb jpg in Paint, Winamp with empty playlist, 1mb pdf in Acrobat, small project in Visual Studio, Nokia PC Suite, PowerDVD, Firefox, a folder in Explorer, Notepad and Resource Monitor, this is on top of my Anti-Virus, Firewall and a few others that load with Windows (76 processes on boot). Now this is what Resource Monitor tells me
In Use: 2540
Commit: 4242/8188 (From Task Manager)
Then I ran Crysis2 and loaded my game then ALT+Tab out, fps were a little dodgy.
In Use: 3483
Then I closed all programs except Crysis, fps good again.
In Use: 2801
One question I would ask is, have you made changes to the page file or does Windows manage it?
If Windows does not free the ram when you run the game you could try running a ram freeing program before playing and I would also suggest closing all unnecessary programs before playing.
