Game does not feel optimized

[Vixrock]

Running 2 Gtx 580 in SLI,
2600k @5ghz
4gb ram
SSD with 500mb read/write..

still laggs heavily from time to time. its playable and its release day, plus FG is still a rather small team. to be honest, the grafics themselves were awesome(i just played the end) and im very impressed with the work.
give it a week or two, i guess a few patches will help. did the game without bugs showing up. thats more than way bigger companies can archieve.

Well done FG!

Honestly I give new games at least two weeks before I jump in, to allow the patches. With SOMA I dove in head first and kind of regret it.
