@VanillaLucia Haha, they seem not to forget to mention AVX support is a must.
The announced requirements is for running the upgraded PSO2 in the lowest setting 1 (probably the same setting revealed in the latest livestream, scaling from 1: minimum to 6: ultra). I personally guess that NGS also runs under the same spec if the graphic setting is set to 1.
The related note on the original notice is this part.
Very roughly translated,
This requirements are expected to be capable of having an average of 30fps (or more) on the multi-party quests of PSO2, when the PC version "simple" graphic setting is set as 1. Still, if there was other software running, the fps can become lower.
