not to hijack Stodd's awesome thread but am guessing he won't mind much. What systems are you guys running SH4 on? I've been tempted to try it out- actually always wanted to try SH3 but the Stardock (?) issues scared me off. I am not sure I have the horsepwoer to run SH4 correctly.
Starforce? Or what ever it's called. Everyone whines about it but it's a non issue. Just don't install it.
System, good question it does take a good setup. I have a E8400 @ 4.2Ghz,4GB Ram and 2x8800GT SLI. Now running on all sliders at max no matter where I am and the size of the battles it seems to lock at 60fps. Though that rig is a bit overkill for this, at a guess I'd say a 2.6+Ghz CPU, 4Gb Ram and a 8 Series card is enough to run at max. You could get away with 2Gb ram but ram is so cheap just go with 4Gb.

FPS has an impact it slows down the cursor to unplayable levels. So yes to really enjoy it with the graphics you need a good balanced system. Luckily these days components are cheap and overclocking is a breeze to get even more out of em..
Flank speed at 60fps.
