What?
I would suggest Decreasing the Sprint speed by about 15%
and the Initial Side step/strafe distance & speed by about 20%
Why?
This would aid in Immersion as the Sprint speed in its current state is similar to that of an Olympic runner.
Decreasing the initial step distance and speed of Strafe will make Navigating in small rooms such as houses less frustrating and more realistic.
How?
Adjust the Movement speed and distance in the normal manner.
