ok so i have been playing warrock for quite a while now and the Pf Usage keep on going up to 1.50GB of usage and its lagging me in the game. before it was at like i dont know but im guessin 20-30GB and i didnt lag at all. now its massive lag. i dont know how this started and people keep saying to close all applications, xfire,msn,blah blah but the thing is i dont use any of those and the only application running when i play the game is only the game. so i came here to ask how can i fix this Pf usage thing. please dont say buy more RAM because i wont bother to buy it. and here a picture of me in the game witht he Pf usage on the side. and some people said to use the "virtual memory" , but i dont get how to use that. i have 1.43 GB of RAM and i dont know what to put for the inital memory and maximum memory. they said that would fix my problem but i didnt know how to use so.
