When I try and use the boost it feels dreadful. It's nothing even close to how the curve feels by a long shot. What is everyones exact settings using this method cause I feel I have to be messing up. I'm on ps4 as well and have been using the 8.5 curve....
Scratch all of that. You must have the latest firmware for the boost to work, I was on SA5 and i felt like trash but now i'm on the latest gold and its great.
That is because the boost function does not function normally on most of the steady aim firmwares.
The steady aim function in most of the firmwares basically takes over the boost box and uses it for the steady aim function instead. So you cannot use this method with those firmwares (the only steady aim firmwares where boost functions normally is SA03, SA04 and I believe SA02). Besides those 3 builds, boost will not feel the same.
I also made another discovery about curves when experimenting between the various SA firmwares and the regular gold build firmwares. With the SA firmwares, there was a difference introduced in how curves behave. Instead of the 125% scale that curves have always been on, with SA01 and onwards (so that would be SA builds released 20160624 or later) the scale was changed to 100%. Mist or OBsIV can correct me here if I am wrong but this change would cause curves to feel different for people who are on different firmwares. Leading one person to feel like the curve feels off, whereas another person might feel it works great.
I first started using the Linear Ramp workaround when I was on SA0 firmware and it felt great at the time (I was not using the steady aim feature, just happened to be on SA0 firmware at the time). I then upgraded to SA03 and all of a sudden I didn't have that same feeling anymore and was missing a lot more shots. That is when I realized that there was a change in how curves behave between those two firmwares. Maybe some people might not notice it but I did immediately.
Anyways, if you are on a gold build there is not much to worry about because those run at the regular 125%.
So for people using the old curve method and have noticed a weird feeling when switching around between firmwares, this could explain that.
HOWEVER, if you end up using the boost method for Linear Ramp, then it should not matter what firmware you are on as long as you avoid the SA firmwares that take over the boost box. SA02, SA03 and SA04 would be the "safe" firmwares to use with boost method.
Hope this helps!
So if I Have understanded u correct the linear performs best with 125% scale? And can only be found on SA0? If u Have newer firmware its 100% and isnt same? How about the latest official firmware? I am on SA03 atm and IT feels awesome but if there is something betyer I would ofc want to try IT. Can u explain this more detailed to me? And how can I see if IT is 100% or 125?
Only if you use the curve method for Linear Ramp would you be affected by this. All firmwares are on 125% EXCEPT for all of the Steady Aim builds. Only the first ever Steady Aim build (called SA0) was on the regular 125% scale. The rest of the SA builds were on 100% scale. And if you are on a gold build such as 20160405 or 20170103 then you can rest assured that you are on 125%.
Personally, yes, I found the curve that I was using to feel better on 125% scale. But it is a subjective thing and someone else might feel differently about it. If you are already used to your current curve at 100% scale, then changing it now might feel weird to you but you could always give it a shot.
On the plus side, if you use the boost method, you don't have to worry about all this scale nonsense

Also you could probably "convert" your curve to work with a firmware that is using a different scale.
For example, when I was using firmware SA03 and realized the scale was different, I simply tried converting my curve and it did seem to work properly afterwards when I tested in game.
This was my regular curve (which I felt worked good on 125% scale firmwares)

>>> XIM4 [Mouse Ballistics] START PASTE >>>
X4MB:AAAAGgA0AC4AMAAwAC4AMgAwADEANgAwADQAMAA1GCIsNkBKVF5ocnyGkJqkrrjCyMjI:X4MB
<<< XIM4 END PASTE <<<
This was what the curve looked like after converting it for use on 100% scale firmwares:

>>> XIM4 [Mouse Ballistics] START PASTE >>>
X4MB:AAAAGgA0AC4AMAAwAC4AMgAwADEANgAwADQAMAA1GCIsNkBKVF5ocnyGkJqkrrjCyMjI:X4MB
<<< XIM4 END PASTE <<<
Basically just took the old one and cut it off at 75% to account for the 25% difference in scale.
And to avoid confusion, once again want to state for people who have moved on to using the boost method to not worry about this scaling stuff as it does not affect you.
