First of all I know this game is in its alpha stage, and optimization might not be the best.
I tried to play this game with my laptop, hoping it can run on a playable framerate (>20), after trying all the different config suggested on the forum, and turning and disabling all the graphics to it's lowest, my fps in sp doesnt even go above 15...
My laptop spec :
Asus N81vg
Intel core 2 duo p8700 2.53Ghz
4 GB of RAM on Windows 7
GeForce GT 120M (1024 MB)
ps: the laptop is not anywhere near overheating ingame.
