Alright I've been experiencing a little bit of a technical difficulty. I'm not sure if its a video problem (which I highly doubt) or a steam problem (I missed most steam updates so they may have been jacked up in an update and I didn't know).
Alright, on Christmas Eve I installed 1gig of ram an an ATI X700 and finally started playing HL2 without having to cheat to stay alive (yeah it lagged that bad, [which actually wasn't lag just low fps so no one flames me about that]). And now I've had a problem that some models don't appear. And when I say some models I mean vortigaunts. I've verified the game cache TWICE and they still haven't appeared. They appear in Garry's Mod 9, and Lost Cost and Episode one don't use them (except for purple which do show up). They're just plain invisible, they talk, I can bump into them, even going into black mesa east the one's knife and hat was their!!
Any suggestions??
