To start it off, generally I am bad when it comes to delving into computer problems but am competent to a certain degree. I have a Windows 8 computer with an AMD Radeon 7450 and it is semi-new. I am an avid steam user and recently, I have had problems getting certain games to launch (Worms Armageddon and Just Cause specifically). Also, BF3 is unplayable due to FPS lag (even when settings are on the lowest) and I have to play League of Legends on the lowest settings due to this lag. I searched and ran the fixes for my Worms Armageddon problem to no effect. Any help would be greatly appreciated.
