X360 controller problem

Thanks for the post. Do you have access to a different pad to test that one instead? Perhaps there's some very minor damage and the maximum trigger pull isn't registering. In some games this won't be noticed, but perhaps it's a factor here. 

I take it that you're trying to fire from the aim stance?

I don't have have another controller.

Yes, fire from the aim stance. 

New discovery, if i push trigger very fast, so shoot.

Thanks. It sounds like a very slightly damaged pad, in such cases a rapid or hard trigger pull can register. 

If the fast trigger pull is enough to let you play, hopefully you'll be able to use the pad as it is from now on. 

Past this, there are various ways to modify trigger sensitivity on PC, perhaps that's something you can look into? I don't think there's an official option but there should be 3rd party methods.
