I got Halo 5 on PC and found the mouse look sensitivity to be too low even with the sensitivity and mouse acceleration settings cranked to max. Is there a way to further increase the sensitivity?
Too quick of movement loses some realistic body movement can happen when sensitivity is high. It already happens on max settings and button lay outs.
I don’t think that you can further increase your sensitivity.
If you’ve maxed out your sensitivity, try putting your dead zones to 0%. It’s marginally faster, but it can make a huge difference in close quarters (or Infection).
You need unreal tournament 3 sense settings 
Spinbots heh
