Specs : i5 3550p 3,1 GHz / 8Go RAM / HD Sata 2To (dirty ol' WD) / Geforce 660 Gtx
using Nvidia Inspector 4x AA 4x SGSSA
around 80 fps BUT... dropping to 30 in pve 8 / 15 in pve 16 / between those two in pvp mass fights
i hate those fps drops.
found nothing to get rid of it. bearable but slowing the game a bit.
