As soon as I pick up the mushroom sample in the caves, the game crashes. I have also had several issues with the game crashing frequently despite deactivated TabletInputService but the game specifically crashes at the point I grab the mushrooms. Any and all help ould be greatly appreciated.
Thanks for getting in contact and sorry to hear you are experiencing these issues while playing Far Cry 3. If possible could you confirm whether you are receiving any specific error messages when this occurs or if your came just crashes back to your desktop? In the meantime, while I understand you may have attempted some of these steps, could I suggest working through this support article.
