Hi guys; I just tried a free download called "Vista Services Optimizer". On my lowest fps I got 7fps increase. In some high scenery areas I got about 20 fps. I am using 64 bit Vista. It is the first program that has given me any fps on the low end of the scale. It gives me over 400fps on the high end. All I really care about is getting the low end up. Still searching for 8 or 9 fps on my very high scenery areas. If you are looking for a little fps increase, this just might be what you need.
