PC System Analysis for FreeStyle 2: Street Basketball
The graphics of FreeStyle 2 look good for their style, utilized via the Unreal Engine, for the smoothest experience, you require 1 GB of RAM, a decent GPU (2005-2017) and a good CPU, a Pentium 4 would suffice.
For hardcore basketball fans that can’t get enough action on a mainstream basketball game, the MMORPG game FreeStyle2, the successor of the popular FreeStyle1 is here to kick up your feisty-seeking-meter to maximum.
