you should be able to just delete yours in offline mode(so it doesnt load a cloud savefile) and then let the game restore itself , that wont mess with gpu and cpu specifics 

There will be some system specific info in it, but here it is.
GameSettings.ini

Xfactor is not a part of the hipfire sensitivity, you have to select a scope for it to show up.

you are matching hipfire with hipfire
just set both to all and the xfactor (which only affects scopes ) shows up
 
(if you set your siege hipfire to 1 and let the multiplier deal with it ,the discrepancy gets  lower)
+ in order to correctly match your fov you'd have to use 73.74 vdeg
 
if you are using 1.0 for scopes in csgo setting your scale to 133.333%vertical monitor distance might help

 
 *friendly reminder that you can currently only match 1 scope  accurately without having to change the numbers every time you swap the scope you use
play on the test server for a couple of weeks for the best experience
