This has only occurred over the past few days, but when I play some games (GTA-SA, GTAIV, HitMan series, Renegade, Oblivion) just to name a few. The main character walks at a high rate of speed causing the little guy to run into walls and things. As you can see it is not a particular game maker such as RockStar, UBISoft, so it must be a setting of some kind. I use windows XP servpk 3 build. ASUS 2.4GB dual processor, 4GB ram, GForce 9500 graphics card, Realtec sound. My games are on a 500GB hard drive and use a combined total of 149GB. And up untill recently they worked just fine. So I would appreciate any clues that anybody might have, I really would like to get back to my game. They are all un-playable PLEASE HELP ME!
