Hi all, I hope you are enjoying the game and thanks for all the feedback so far.
As I am hearing reports on performance issues in the opening area I will be putting out a patch today that will hopefully fix this. If you are supersampling via Steam renderTargetMultiplier this may also cause performance issues if set too high. I run a 1080 GTX at 1.2.
I will also tweak the darkness at the beginning of the game and/or give the player a more efficient torch light.
The keypad in the hallway cannot be accessed until the gas is switched off, this will be also be signposted more clearly in the patch.
