My computer used to run Cs:s at atleast 80-100 fps on the lowest settings, about a year ago. Now, it can hardly run 20-30 fps on the lowest settings . I don't know what has happened and its really annoying me. I have cleaned out my computer for malware and spyware. It has increased the speed of my pc and I'm impressed, but my graphics lag in Cs:s is TERRIBLE.
