It's PERFORMANCE not LATENCY so yes I'm sure its the 360 and not my internet. If it was my internet actions would be delayed. I'm talking choppy performance. Also, mobs always spawn on the 360 latest, there is no doubt the 360 is the inferior version of FFXI, but that doesn't mean it has to remain that way. (If you compare a 360 and PS2 side by side, monsters spawn on the PS2 first, 100% of the time, and actions are performed faster.)

Have you never used your 360 at Fafnir and seen it as a slideshow or done an 18 person abyssea at altepa?
The 360 performance is just ... awful when there are a lot of players on the screen - so an option to toggle Shadows should resolve that. Frames per second often drops below 5 when in combat and that's near unacceptable for a system like the 360 - the graphics are just turned up too high, and giving us the option to control those settings, like the PC version, would allow the user to play FFXI in a way where we balance Performance vs Visuals.

I'm using the new 360 Slim as well.

A PC will never drop below 30 FPS, where the 360 will only reach 30 FPS if your standing in your mog house usually. (30 FPS is the cap for it).

Laptops usually don't perform well with FFXI as they tend to use inferior graphics cards, and even with a good graphics card, often have inferior drivers. That's not to say laptops can't handle FFXI, just a large % of them won't handle it well. My macbook pro handles it flawlessly.
