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?

Nobody any ideas? It's really bloody annoying, it plays every other game fine but Sims 3 seems to keep moaning about the drivers

 

Hey, I had the same problem. Not sure if you've figured it out yet, but I did.

That explains the steps I tried and the final solution. Read the top part in the blue box, at least.

And here is the modder that I used on the drivers

Good luck!
