Ok, so recently I figured out how to crank up my AA settings through my nVidia control panel.And as great as it looks, when I open Squawk Box, something happensThe Squawk Box module creates a line that separates my flightsim. The bottom view in that picture doesn't move, but the upper portion, separated by the module, moves. This only happens when I crank up the settings. Why is this happening?!

Your graphics are integrated. 8xS is not a setting you should ever apply with that graphics chip.

Well can I do any setting above 0? Like 2 or 4? Or is my graphic card just too terrible. (Old comp)

2x maybe. SSAA is too much to ask of any integrated graphics chip though. You should use standard MSAA to have any level of acceptable performance. That or buy a cheap grahics card. Even a 9600 GT/9800 GT for < $100 would be enough to handle some level of SSAA.
