I did some tests with this 1.02 patch. There is less stuttering issues, it's clear. Without the patch, even if the game is installed on a SSD, the game stuttered.
Unfortunately, I have the "40fps bug". Afer a few minutes, the game automatically locks himself on 40 fps.
I don't have any V-sync issues with or without the patch.
My hardware :
Intel Core i5-4670K
8 GB DDR3-RAM
Nvidia GeForce GTX 660
SSD Sandisk Ultra Plus 256 GB
Windows 8 Pro x64
I hope you will release the patch soon, I really enjoyed this game
