6.42 update

In this update, the executable will now automatically select the best graphic adapter (for ex Nvidia or Amd) in priority when the computer has several ones: this is the case on many laptops that have an Intel HD adaptater on the mother board in addition to the big 3d card. In this case, if the Intel card was selected, this made the game slower, but also could lead to random crashes if drivers were not uptodate.
