These games are so advanced that at times some of the issues that you encounter the problem lies with the particular machine you have, or the graphics card, or software installed. Remember these games are not tested on all systems. They are just tested on compatible systems granted you have something that runs on a similar OS and compatable machine. These games are tested in a closed environment on a certain type of machine. Trust me the machines they use are worth more than we are willing to spend! Sorry
