Windowed Mode

so there's three screen modes; Windowed, Fullscreen Windowed and Fullscreen
but for us, only Fullscreen and Fullscreen Windowed can be selected
all settings are on lowest, 16 bit instead of 32 bit, 800x600 instead of 1200x800(wide), all effects and textures at minimum
so why cant we go windowed? fullscreen severely limits the amount we can do without getting screen lagg

I play windowed mode, hmm maybe you got low/small resolution?

Might wanna check the graphics card you have, and your drivers...

Sounds almost like your drivers/card aren't being recognized by Aion itself. So its forcing itself into a basic mode to let you play without losing its mind.

I can only really suggest finding/updating your graphics drivers, see if that helps. Unless you have an older graphics card that might not be able to do the work at all. Some games are getting to be royal pains when it comes to recognizing even newer cards anymore.
