Okay. This is REALLY frekin wierd.
About a month ago, If i tried to play half life 2 with everything on low quality settings, my computer would still lag.
So i decided to d/l and play day 14 (great game) and i put everything on medium quality, and texture detail to full, and it played with no lag what-so-ever.
