Low Perfomance

If you can play battlefield 3, i dont see a reason that Aion should lag to you.

Maybe it's because of your internet connection, if it takes 2 days for you Aion could lag because of the slow connection... However try reinstalling it if it still keeps lagging just lower the settings.

 

i had a similar prob once, and its FPS lag not net lag, 2 different things. If you downloaded from a 3rd party and not NCSoft then delete the entire Aion client and redownload using the NCsoft launcher, but if u have to use the 3rd party then when u download it, delete everything from bin folders, L10N, effects, basically all the big folders, some places "convert" the files to make them smaller or something and its ****s up the optimisation of the client, then do a repair using the client, it SHOULD help. Helped me when I had same kinda shit going on
