problems with graphics (Rune Classic)

Guys, help! Wanted to play Rune, run it, and all the character models are translucent, and the weapons - no. I.e. it shines through modelki characters, i.e., if the sword in his right hand, as I look at the Persian left, still see the sword completely. Or closing the shield. and looking back. it seems that the shield is back. blocking the back. Please help me to solve this problem. And another thing: when I choose hardware video card - for some reason runs in Windows only...
