Increasing FPS will also make it load faster.
In the beginning my game was hardcapped at 30 FPS, and my loading screens took for ever.
Once i removed the FPS cap, using this link: http://steamcommunity.com/sharedfiles/filedetails/?id=551069501
And then used a software to cap my FPS at 71 FPS my loading screens are now atleast 3-4 times faster.
PS: You must cap the game at 60-70 FPS or it will not function correctly!
On a side note... using a program such as ParkControl, and set the program to "max performance" will utilize all your CPU cores, which can give a performance boost.
