The Heroes Round Table

If drivers update won't solve the issue, try to use dgVodoo: https://www.celestialheavens.com/forum/10/16658
It will wrap the game to use modern DirectX, rather than DirectX7.

This did the trick, thanks a lot!

I also have this problem, except the game is completely unplayable using the integrated graphics. It looks something like this:

It just flickers wildly and you basically can't see a thing.
