Well then I'm happy for you Mr Moe.
But this is not something I have made up.
It is a Nvidia driver problem and it affects people with the 8xxx and 9xxx series cards and WinXP.
I read in your previous post that you have, but don't use SLI with RO.
But perhaps it has a positive influence on your system anyway? I don't know.
I've seen posts by others with SLI setups saying they don't suffer from the stutter bug.
Try running RO with only 1 of the cards installed and see if it makes a difference.
If your still bug free, then am sure quite many would be happy to know everything about your system
You can read from this thread that several people including me have tried the 174.74 driver report its not fixed.
But some say the driver performance is better.

RO is just 1 out of many games that suffer from the bug more or less.
I can play RO fine for most parts but indoor environments in general are not so good.
Danzig is perhaps the worst map and this is why I always test new drivers there.
Ramm-Jaeger.. Can you tell us a bit more about what you're testing.
Will it be necessary for Tripwire to make adjustments to RO?
