It is definitely not a driver issue, I've installed multiple drivers (including beta ones) and they all have the same problem. I'm hoping it's either a map issue or a game issue or a fixable vista issue. I don't really want to reinstall Vista =/. 'Retry' ing the server seems to help a bit but the fps drops are still there around pit and in T spawn.
Also sometimes the FPS drop(it stays around 20-25 FPS or so) holds constant for other parts in the map and then suddenly goes away when i get to certain places, but not always such as around 'side' and in 'middle'.
I don't know if it is possible to reinstall a particular map or if I should just reinstall the entire game, Office seems to work just fine, Haven't tried a whole lot of other maps.
On a side note I'm only able to overclock my VRAM to about 850 or so or else I start to get artifacts. Core Clocks fine. I'm definitely going to step-up one of these days though. Might as well use the feature if I have it, right?
Anyway, I'll post my problem on the Steam forums see if i can get anything there.
