Vince Zampella, Director of Respawn Enterainment, took to twitter to announce the minimum specifications for Titanfall on PC. However, you are going to have to have a pretty beefy rig to handle this game. They are looking for:
64-bit Windows 7, 8 or 8.1
AMD Athlon X2 2.8GHz or Intel Core 2 Duo 2.4GHz
4GB RAM
512MB VRAM
Radeon HD 4770 or GeForce 8800GT
So there you go, can your rig handle the load?
