I recommend this mod for high-end pcs but if you want play this mod with medium or low texture setting:
1-open f_y_stripperc02.wtd with openiv or spark
2-extra some heavy textures like head or uppr..
3-open textures in photoshop or.. and change texture resolution(for example 2048*2048 to 1024*1024)
4-open f_y_stripperc02.wtd with openiv again then replace new textures.
