Muscle memory, having the cursor / aim be an upredictable variable depending on the speed of the movement feels very wrong to me.
Floaty feeling, one of the things I try to do first with every Bethseda game is to try and force raw mouse input, otherwise it feels like I’m trying to control a mouse cursor that is sliding on ice.
I have not tried the RawAccel druver you’ve linked so can’t comment on that.
A surprise that this isn’t an RPG like the previous two games were. Can’t say that it peaked my interest at, at least for now.
