TL:DR - The update is broken for anyone using Intel HD graphics.
Win7
i7 2.6Ghz
8GB
Intel 5500
This thing isn't a powerhouse but I've had 0 issues until Patch 0.11.0.7844. Played yesterday for 5+ hours with FPS between 25-40 and 0 crashes. Today I load up the game and it's unplayable ranging from 1-3 FPS.
Tried playing with graphic settings - no change
Installed newest drivers - no change
Windowed/Borderless/All rez in the dropdown - no change
Steam online/offline - no change
Hosts file - 0 entries
The only option at this point is the update. It was noted that support for integrated Intel graphics has been improved, something tells me this change is the cause.
I'm open to other suggestions if you can think of something I haven't tried =)
EDIT: Just reverted to previous version and FPS jumped right back up. The update is the issue.
