Bringing to NextGen patch 4.04 this awesome mod by 10010001. Sprint and swim faster. The original mod had two files. One is for faster base speed and a second that allows gamepad input to vary the speed. I've combined them into one because I personally use a controller for the game. The author has not been active for awhile so this is me helping serve my brothers and sisters that have been looking for an update to next gen. Of course once the author decides to update the mod officially this page will be removed. If you have any conflicts that have to be manually edited I'm not likely able to help. This was easy to update to next gen but I'm not well versed enough with scripts to make compatibility patches. So sorry in advanced if it has hard conflicts with other mods you are using.

You can customize this to your preference by editing modSprintingSpeed\content\scripts\game\player\player.ws line 38:

private var sprintingSpeed: float;default sprintingSpeed = 1.6;
private var swimmingSpeed: float;default swimmingSpeed = 1.6;
private var divingSpeed: float;default divingSpeed = 1.8;
private var runningSpeed: float;default runningSpeed = 1.2;
private var modSpeedInCombat: bool;default modSpeedInCombat = false;

You're welcome. Va Fail. 

Compatibility

• Smooth Movement the latest versions seem disable the effects this mod offers. (at least for my use case) Just PSA unfortunately since the original author of the Sprinting Speed Mod has abandoned witcher modding I'm not skilled at making compatibility patches. Or making any improvements to this mod. I've personally stopped using this mod for I prefer the smooth movement mod. I will however continue to update the scripts within this mod to the best of my ability as CDPR releases patches.
