Topic is pretty self explanatory. I have a pretty high end laptop that runs the game on high, but I'm still curious as to what some of the options really do, not only for myself but for the benefit of my friends who recently bought the game who are tweaking the settings as well.

The settings in particular I'm wondering about are the following:

Texture (normal vs compressed)
~~~ Filter (I'm playing JP so I can't read the kanji) - On vs Off
Motion Calculation (CPU vs Hardware)
LOD - All the settings here are set to 32, but I have no idea what effect they have

So if anyone could lay a little knowledge on me, and tell me what effect these options have, I'd be very grateful. Thanks in advance to all replies~
