Why can't I shoot with a machine gun by holding down the attack button?

[Grogrokl]

When I shoot with a machine gun, or any weapon in the game, I need to do 1 click on the attack button for every shot. Aren't you supposed to be able to shoot continuously by holding down the attack button? Is it just for me holding down the button doesn't work or is it for everyone? How do I fix this? A setting that needs to be changed? A mod that needs to be downloaded?

 

update: After some further testing I noticed it was possible to hold down the attack button for some weapons. But there are also some weapons with very fast attack rate where you can't hold it down, any way to fix these weapons?
