Hi there, I have a Dell Inspiron N5010 laptop with 2.6 GHz i3 processor 3 GB RAM and 1275 MB shared graphics memory and Win 7 64-bit. My dad used it for his office work and now gave it to me. I tried running some games like Call of Duty 4 Modern Warfare, Call of duty 2 and Assassin's Creed 2 X men origins Wolverine Resident evil 5 etc. I face terrible lag on high graphic setting in COD 2 the game ran at 15-28 FPS on an average while cod 4 mw gave me terrible lag. Ac2 also is lagging terribly and some games like NFS MW and POP:WW which ran fine before now are lagging. I have tried updating my graphics card driver but no affect that only blurred my in-game text in COD 2 & 4. Would like help from you guys whats can i do to speed my games up???(I have tried Game booster etc)
