yesterday i download CSS from steam. i log on to a server and i get a SUPER BAD lag, like a slide show, but it only does this when i try to move or shoot. if i look around no lag at all i can see everyone running around and getting shoot, i can even hear the people talking. but if i try to walk the slide show starts. i no its not my pc that cant handle it, iv been playing left 4 dead, fallout 3 and dead space on it with no problem at all. my internet goes about 80kb-88kb. anyone have a idea what it could be?
