Very noticeable m&kb input lag on PC and the lack of fullscreen

Is anyone else experiencing really massive input lag on m&kb when playing on PC? I remember having this issue during the flights but I thought they would fix the issue in the next release I feel like the input lag is now even worse I can barely aim properly like I used to in MCC and I’m pretty sure being caused by the lack of fullscreen every game that is set on windowed mode only has input lag, how come 343 thought fullscreen was absolutely unneccesary?

Yes I’ve read their post about why they thought it was unneccesary but that isn’t true at all in my case, Windows full screen optimization does nothing for me, I’ve disabled it and it didn’t fix it, I’ve also noticed that the game seemed to run fine (input lag present tho) at 60 fps but when I minimized the game and then returned back the game experienced massive frame drops and it started to run at 15-30 fps only even on 4v4 (this shouldn’t be happening, I have more than enough ram for this game and this is the only game that behaves this way, no other game gets massive framedrops after minimizing it) the only way to fix this was by restarting the whole game.

Just in case you want my main specs here they are:

CPU: i5-10400
GPU: RX570
RAM: 24 GB 3000 Mhz
STORAGE: Samsung m.2 970 evo plus

In the meantime, have you found a way to fix this issue? I really hope 343 changes their minds and add fullscreen for full release.
