1. My machine:
GPU: Nvidia GTX 770M
CPU: Intel i7 4700MQ
RAM: 16GB DDR3 @1600MHz
Hard drive: 750GB HDD @7200RPM
2. Settings ingame:
Although I didn't think the game was lagging due to my machine not being sufficiently powerful, I tried turning every graphics setting off or on the lowest setting. The issue is still the same, so I think the problem has something to do with the software, not the hardware.
3. Resource hogs:
At first, I, to be honest, did not know what a "resource hog" was supposed to be, really. I searched for it on the internet and found out it was "a function or program in a computer which slows down processing". I have never seen, in a game or otherwise, an option titled "resource hog", so I THINK I have them turned off, if that is the default option.
