ok. Here's my view:
It works fine with 384 megs. 256 probly is ok. But with 128, you're not going to be doing any flying that's fun, due to HD thrashing.
As for FPS, well, it all depends. THink of AH. Normally, you're flying with maybe 5 other vehicles in the visible area.
Now think of WW2OL. THere are areas of sparse battle, then there are the "hot spots." Imagine a combined-arms fight over a town with 100 vehicles and troopers slugging it out, destroyed buildings, smoke and the rest. That's cool as all hell, and a helluva lot of fun to be in, but if you're trying to fly a plane, you better have one sweet rig.
If you go for areas of medium activity, you can find decent FRs. Not great, but decent.
On the bright side, there are things that CRS can do to improve FR and reduce HD thrashing, and no doubt they will. So it only gets better.
