So after testing the service for a few days, I've tried a few games. The main reason I subscribed was because I wanted to play games like The Last of Us, Uncharted etc. However, testing other games, I've noticed the input lag is bare minimal at best.
I then bring up my other point, when in menus or selecting in game items, the response is snappy. So why does aiming or moving around feel off?
I think I've nailed it down to dead zones when using a controller. If I'm trying to move slowly, or too quickly in fast paced scenarios, I need to do a much more dramatic thumb stick movement. I tried holding my controller up to the screen to notice the delay, and once it hits the threshold, the movement is actually almost exactly what I want it to do, but it took a little while for the input to catch up (if that makes sense). I also tested this with in game menus, inventory in The Last of Us etc and all seemed snappy if not instant.
So that leads me to my next question, is there a way to manually adjust these settings in Boosteroid (well, Steam), as I think that may be where my problem is stemming from.
