Hi. [First of all, mods please move this to the appropriate forum if ever I'm wrong in putting it here thanks] I have been having windows vista for a while now, probably more than 6 months, and I didnt have this problem before. I play a certain mmorpg, which is not really graphically demanding, and it used to play smoothly up until this past few days. Now whenever I play the game, it looks like the a stop-go motion, like something else is running or the computer is having such a hard time running the game and ruins the gameplay experience. Other people call it choppy graphics, where it used to be (for example) 60fps now seems like its 20fps. I have not installed anything out of the ordinary, have loads of hard drive memory. I also checked the task manager, and it shows no other application running. Sad thing is, even if i set the mmorpg game to 800x600 resolution, first it will run smooth, then it will go choppy chop once again.. I never had this sort of problem up til now. Please help.
