-------------------------------------- Color space --------------------------------------- 

For PBR textures is best to use Linear Color Space.

1. Click -> Edit -> Project settings -> Player
2. In inspector -> Other settings -> Color Space -> Linear



-------------------------------------- Scale textures -------------------------------------- 

Texture set are:
Axe 4096x1024
Sword 4096x512

If you like to scale it down: just select all texture in Texture folder and change max size from 4096 to your resolution needs (Inspector tab).
