You're more than welcome!
I hope it can both improve the CFS3 experience for someone, and save them time in getting to the root of their specific problem with things like shimmering or micro-stuttering.
In my case it started with shimmering that was driving me to distraction. I had always tried to optimize for more and more FPS, and didn't really know how little it really mattered to the experience. Obviously there is a minimum acceptable rate for good game play (>30-40 fps), but beyond that it's all about making it look as good as possible. Once I cleared up the shimmering then the micro-stuttering became more noticeable, and on and on it goes if you're not careful...
These sort of posts are invaluable, even if people have to individualise the settings slightly to suit their own PCs...
