Maybe the internal reciever only works with one controller, opposed to the dongle's 4. This is the first time I read anyone trying it out with two. Tried to add it manually with a cable for ex and then unplug it?
Yeah, I tried the cable, everything. Did not know that the dongle supports 4, that may help out down the road. (big family wanting to play multiplayer games)
I think I may use another FPS to get used to the controller. I think Fallout 4 may have some weird issues. Like, I had the left stick set to scroll wheel, with clicking it changing between first/third person, but over the half the time I clicked the stick it wouldn't work. And using the left trigger to dampen mouse acceleration, sometimes the dampening was huge (only tiny adjustments possible, and only on horizontal plane) and sometimes it gave me what I wanted, slower adjustment. The inconsistency drove me bananas and I ended up wasting most of my ammo when I couldn't aim down to shoot a molerat, and got frustrated trying to deal with the controller and being out of ammo to keep practicing later against raiders.
Plus other games don't make me nauseous while testing. :/
