The Barbarian 8K Skin Textures For Genesis 8 Male & G9 is a texture add-on that provides you the Barbarian skin textures in 8K resolution.
If you want to see how much your system can take, this pack is for you ;)
To use it properly, you will need a strong graphics card, I would not recommend using this if your card is under 11Gig GPU.
In addition, you will need lots of storage as these maps range over 1 gig in size.
