I'm having a severe issue with lag in Might and Magic VI. Every action I take in the game, even in the initial menus, results in a delay. The game freezes for a few seconds, and then unfreezes with the selected action completed (I.E. opening inventory/options/maps/etc., attacking, movement). Movement is the worst, I can turn with no issues, but attempting to move either forward or backward results in lag. I can only move for about a second before the lag hits, and then if I don't release the arrow key quickly enough, the movement will continue until the lag ends, which causes me to shoot forward great distances. I have even died (oddly enough) from running head on into walls this way. The game is completely unplayable like this, which is pretty depressing, as I have loved this game more than nearly any other game, but haven't been able to play it for a decade and a half now. Someone please help!
