Evening folks..
We've just pushed a new patch to steam to address the following issues:
It includes all fixes in previous patch http://steamcommunity.com/app/319630/discussions/1/612823460253433966/
- Fix Non Unicode OS users not being able to boot Game. *fingers crossed*
- Address the echoing/stuttering sound issue – sound should now not stutter unless game performance drops to 5fps and lower.
Thanks again for your patience
