@ind3pend3nt182 @KeyanShin @Sunmoth
I beleive you guys are having these issues because your laptops are borderline minimum, if not below. Even though you have decent processors for a laptop being i7's, they are still laptop processors and are clocked at a much slower rate than a desktop processor. The minimum requirement i3-6300T is @ 3.3 Ghz, when yours are around 2.4-2.6Ghz, which is quite a bit slower. Also, all of your processors are below minimum. I will post the specs below, and show you all comparisons of yours vs the minimum. Also, you are all at borderline minimum for your RAM @ 8GB, and @KeyanShin is under with 6GB. This is by no means the main cause of your issue, but it surely doesn't help.
Minimum PC System Requirements
OS: 64-bit Windows 7 or later
Processor (Intel): Intel i3 6300T @ 3.3Ghz or equivalent
Memory: 8GB RAM
Hard Drive: At least 40 GB of free space
Graphics card (NVIDIA): nVidia GeForce GTX 660 2GB
Graphics card (ATI): ATI Radeon HD 7850 2GB
Comparisons:
GTX 850M vs GTX 660 (I will leave out the 840M vs 660 since this will be lower and for some reason only the 1GB model was coming up for comparison)
GTX 750M vs GTX 660
One thing that may help you all with your freezing would be to change your graphics settings down, and also use "Borderless Windowed" mode or "Windowed" mode instead of FullScreen when playing.
