I've been testing today because many players, myself included, have noticed that physics (especially weapon behavior) feels off. Attacks and overall movement show almost no acceleration.
Looking into the weapons’ Rigidbody components, I found that the Drag and Angular Drag values are sometimes too high. For example, the dagger has a Drag of 0.1, which reduces its current velocity by about 10% per second. This causes the Rigidbody to feel sluggish, almost as if it was moving underwater.
Reducing the Drag and AngularDrag values on weapons and BodyParts will allow higher terminal velocities, giving swings, throws, and unarmed attacks a stronger, more responsive sense of acceleration.
