When I try to convert my MW sens to Rainbow Six Siege I can't seem to get it correct. I understand they can't always feel the exact same since its two different games but my aim in MW is 10 times better than it is in R6 and I have 2000 hours in rainbow compared to the 200 in MW so it makes no sense. My MW settings are: hipfire 6.07, ADS multiplier for all scopes .55, AR 16:9, FOV 90. My R6 settings are: hipfire 7, ADS 50, AR 16:9, FOV 90. If anyone can help me it would be very much appreciated.

You should use the same FOV in both games, which means either set R6 to 60 or MW to 120.
