That is the same program that was used to create the Realistic Running Speed mod. As I statetd previously, the ESPs it produces error out when you try and open them in SkyEdit. That doesn't mean that there is a problem with using them in games, but it is enough of a reason for me not to use the ESP in my games.

Fair enough, I think I'll just wait till the CK comes out tomorrow and we can really see what is going on. I'm sure after the CK is out we'll have a "safe" speed mod.

I've been using it for about a month. No errors/glitches as far as I can tell. I also use my own mods to increase weapon speed, and it plays nice with those too. It does something different with ESPs that doesn't show up in skyEdit. I don't get errors, but I can't figure out what he changed. (I like to consolidate all my ESP mods into one personal ESP) But anyhow, it works perfectly. Nothing to be afraid of. If you're that worried, just copy your savefile to another folder before you use the mod.

I own an Xbox 360 controller, but I prefer mouse and keyboard.

Looking around and aiming with a controller is an exercise in frustration.

The template for Skyrim Speeds mod was created using TESsnip tool from Fallout Mod Manager, but it can be loaded using TESVSnip (Skyrim Edition) without problems. It only changes some MOVT records (copied from Skyrim.esm file).
