Disabling targeting reticle

Hi, I have a quick question, maybe someone can help me out - I am re-playing Gothic 3 with 3d-vision enabled (btw its absolutely awesome), and I have an issue with in-game targeting reticle while using bows (it renders incorrectly and in 2d). I'd rather use the 3d-vision reticle and am looking for ways to disable in-game reticle. Is there a command I can add to some INI file or some such? Would appreciate advise from those with know-how

Cheers
