T60p XP video driver problems

Question

Hi,
Just had to reformat and reinstall my T60p, and have put XP SP3 and the lenovo ATI video driver v8.533 on. Since then, I've had intermittent video redraw problems - parts of windows not being redrawn when minimising / maximising. Seems to affect all applications, and there's very little else installed other than a couple of portable apps.
It seems that sometimes the video performance is really really bad - windows leaving trails behind them when being dragged across the screen, just like an unaccelerated video driver would. And various rectangles of windows failing to be redrawn completely.
But sometimes, its working fine - I can't see a pattern to it (yet). I've tried reinstalling the driver from a fresh download, and I've tried disabling acceleration in the troubleshooting section of display properties, with no effect. And there doesn't seem to be anything in CCC which helps, but for info, here's what it says:

Anybody got any ideas? Are there any later drivers available? I wonder if its related to the screen rotation fix for SP3?
Thanks,

Answer 1

Yes, that's the link I got the video driver from.
I tried downloading the bios flash utility from your link anyway, but it said I already had the latest version (which is what I thought), and didn't need to update. I confirmed this by booting into the bios config screen, and it definitely displays ...3WW there. I must admit I had assumed the bios details from CCC were for the GPU bios, not the machine's bios. But I couldn't find any references to updating the GPU bios.
To confirm, here's the full output from the System Info button within CCC, which displays the machine's bios details:
