So MAJOR thanks to Gunit2004 and humanfemale for helping crack this mystery.
To keep it short we've all noticed that the Linear ramp on Overwatch doesn't kick in right away. Obviously the deadzone is broken, they set it too far away from 0. Luckily our friends here figured out that you can use the Xim to makeup that deadzone and then you have an amazing setting!
1) Copy your buttons from your current profile
2) Create a new CONSOLE CROSSOVER STnot overwatch Profile
3) Paste your buttons
4) Load up a practice skirmish; Linear Ramp; 0 Aim Smoothing; 100% Ingame Sens
CURVE MODE:
-Now start at the lowest part of your curve. Start kicking it up until you can SMOOTHLY move your mouse at a very slow speed (it will start choppy but as you move that number up you'll notice it'll smooth out and speed up, for me that was 12, for humanfemale it was 8 ) it seems to depend on your console, and mouse
-Now add as much to the top of the curve as you did to the bottom.You're trying to maintain that 45 degree slope.
-Now you can mess was sensitivity. No need for a boost. I have Steady Aim on but.... oh and 1.5 Y/X
UPDATED: BOOST MODE: (recommended) (SA3)
-No Curve, Put your boost to 5000 and then start slowly lowering the numbers by 5 until the micro-movements are smooth right before they cut out
EXTRA: Widow/Ana Zoom 41%, Aim Assist Window 5, Aim Assist 20
UPDATE: I ended up with a hybrid. I use the curve method for HIP and boost for my Widow ADS. Kinda nutty but I'm loving it. So close to PC. After months of fooling around with this I think this is what I'm sticking with for season 5 until they patch linear
I didn't paste my curve in here because I think you should try to figured out your own. There really is no curve it's just adjusting the straight line for the deadzone. Too bad you can't just raise the whole curve line with one slider though this would literally be the ONLY application for that.
