UPDATE 9-2-20 Has your Sims 3 game been affected by the recent pixilation issues?

I'm running Win7 with a GF GTX 750ti and my game has always looked like @budewarmin 's game does, with the colour banding, despite having everything on max settings. I've just concluded that is the way TS3 is, and not really bothered about it any more.
I am not having the intense pixelisation that others seem to have though.
