HP/Compaq :: Radeon HD4530 Driver That Works With The Sims 3

I just got my dv6-1131ea, one of the reasons was so I could have better gaming ability with the Radeon card, now I'm playing the Sims 3 and all I get is the following message when I start it up:

"We strongly recommend that you update your video driver"

Which is all well and good but I have the latest driver, there is nothing new on the HP site, or via HP Update, or Windows Update. If I try and install the latest catalyst package it tells me that I already have the most up to date driver.

The game is pretty choppy even at low settings, I have expected it to be much smoother than it actually has been, It's just not smooth and when I scroll around I get choppyness, I'm guessing it's to do with the video drivers but how the hell can I update them when I already have the latest?
