Specs First Althon Xp 1600+ Asus A7V266E 2 x 256 Kingston DDR Ram Leadtek Winfast Geforce 4 Ti4400 128MB Windows XP with SP2 My pc has been running top notch even after installing XP service pack 2. I installed Doom 3 and updated DirectX 9 drivers at the same time. Now I am getting TERRIBLE performance in ANY program. Menus do not render, I am typing about 3x as fast as my computer can keep up, video playback is ridiculously shitty, I can't surf the internet and watch a video at the same time because it brings my computer to a screeching halt. It has taken me over 10 minutes to type out this post because my pc is currently running like a dog with 3 broken legs.!!!!!!!! I already did virus scan, adaware, and checked my firewall and that is all good! I am really getting pissed off and dont want to uninstall Doom3 to fidn out that is not the underlying cause.
