I've been messing around with all of the settings for the last 2 days and no combination of settings feels like other modern FPS games. There's a massive jump in aim acceleration when you move your thumbstick to the edge of the ring, which makes quick adjustments/twitch aiming borderline impossible. The crosshair just jumps all over the place and then I need to try and compensate for this and end up missing. It feels like a worse version of Halo 5s aiming system at launch. Every other game in the series had solid, responsive aiming.
And this isn't an aim assist/bullet magnetism issue. I WANT there to be minimum aim assist/bullet magnetism. The issue is the jarring aim acceleration jump that you can't fix with any setting, even aim accel set to its lowest.
