Got a brand-spankin' new gpu recently, the evga 7900 gt to replace my old ati x800xl. The card runs F.E.A.R. at max settings in everything except the filtering which is at 8x (no small feat...) and I'm still running in the ballpark of 50-60 fps without no hiccups at all. Then.....I boot up CS:S. I pull up the advanced video settings and they're exactly the same as what my old card was.....uh wtf? I reboot cs:s, same thing. I tell myself that's it's just the typical steam being uncooperative, so I boot up the game and start playing spawnpoint cs_assault. I'm surprised to see that the game runs at about the same frames as my old card with the settings only slightly higher. I get fairly ranging frames on assault (as before) now from about 50-100. I know this is odd because most people who have a 7900 gt get at least 150 or so on that map and mine is one of the top of the line 7900 gts. At any rate, I don't really understand what would cause this card to run other games so well but seem to not get along with cs:s, a game much easier to run than something like F.E.A.R.

Any ideas?
