I played on below potato laptop for you to benchmark your own setup.
Playable on LOWEST setting, but not advisable as you will miss out on the amazing game graphics.
Some issues faced when on potato laptop:
*lowest setting makes your game / charcter very pixelated
*game might crash on entering dungeon.
*surprisingly no lag during multiple mob combat.
*lag / high ping comes from your internet connection, suggest you stick to your own area server
*occasional lost of connection to server
Cya guys on the 28th!
