I, like most people, have been counting down the seconds for over a year for the release of Valve's Portal. So needless to say, when I found the game would only run at about 4 fps on max resolution on my PC, I was slightly pissed off. I've tried everything, reducing the game quiality, updating drivers, but nothing makes much difference.
I have an nVidia 256MB GeF 7300GT graphics card. I know Valve recommends using an ATI Radeon card, so this might be the problem.
So what I'm asking is for anyone who has Portal, or any recent valve games, to say what gfx card they have, and how well the game runs for them. I'm doing a bit of research before I buy a new card.
