Overall, all the versions of Gothic II are identical when it comes to violence/gore. However, the programmers developed 3 different degrees of violence. By standard, you get the medium gore but you can always choose to switch it to the highest level (which acutally is not too different from the medium level, since Gothic is not too violent at all). To alter your game, all you have to to is edit the entry "blooddetail" in the file "gothic.ini" (which you will find in the subfolder "system") from 2 to 3.
