I would really like to play this game, I have lowered everything to the complete minimum, ran it in optimization mode, and even resorted to playing in a window to try and play this game. I would be fine with 20-30 fps if that is all I could get, however the highest I am able to get at any time is about 15, and it's even dropped down to one. I have more than enough ram to run the game, however my entire computer lags when it is running as well. My graphics card is very low-end (AMD Radeon HD 6450, I can't even run source engine games on high with it) because I decided to get my PC before I knew a good deal about specs and everything. Any help would be appreciated.
