Ive been playing between K&M and Controller for the past months, theres something that feels off whenever I try to use a mouse for this game and I believe its the movement acceletarion.
Allow me to elaborate, in previous titles whenever a player moved there was acceleration between changing directions, making the famous Halo dance a more challenging skill. Now with the changes in infinite one can straffe left and right without the acceleration holding you in place for a moment.
This doesnt feel as bad in controller as theres a coded program to help one follow a target after its determined one is looking at an enemy, you dont even need to move the right stick, only the left one.
Unlike previous entries, this does not only slow down ones acceleration to keep on target but it actively will attempt to help you aim.
K&M on the other hand heavily suffers here, as the registration will be less accurate than controller. For this my temporary proposal is increasing the bullet magnetism for some weapons in particular so even though these new changes will remain, this would make the vast PC playerbase feel like the game plays better when considering the information Ive already presented.
