You'll find two screenshots here showing what I mean.

So to clarify, this is a bit odd.

I'm not sure if this is in-game due to a perk, or from a texture conflict, however every time I aim my gun in iron sights towards a target, it has a green glow over it that looks like that, (or rather, green stripes over it) before and after it's been killed. (They also look like this weird shroud sometimes) This affects all enemy NPCs. Anything I can do to check?

It's not the worst thing in the world, but a bit frustrating when I'm in a dark tunnel and just see a sea of bright green. No surprises.

Its probably caused by a mod can you write your modlist ?
