I asked few of them. They had the newest drivers. I think that even if they try on previous ones and it will work, than this is not the solution. I don’t think that all of them will now swtich drivers to previous versions just because of our game (I know that other suffers from that too but I assume that it is the only one for the particular person that is crashing). Answering your question - they have (at least some) the latest AMD drivers.
