Please help. I am at my wits end trying to get hl2 to run properly on my computer. I have a brand new Hewlet Packard PC with hardly anything on it. Its a P4 with 1GB DDr Ram, 200gb hd with a ATI Radeon X600 pro, but i don't seem able to sustain a decent framrate, its constantly dropping into the red when anything happens. I'm also experiencing quite alot of tearing/blurring of the images when moving on the horizontal plane. I've defragged the hd, downloaded the update for directx9 and Catalyst for the graphics card, played around with the settings and resolution (even on medium detail its not very stable) but nothing seems to work. I can't believe i've spent a grand and can't get this damn game working properly, this is what pushed me to console gaming years ago. Can somebody help? Am i missing something? p.s It looks glorious if you don't move.
