[ fix ] RDR2 black screen on boot : my solution.

[Frusco]

On my PC the solution is to start and stop RDR2 in "windowed mode"

• Go to Documents\Rockstar Games\Red Dead Redemption 2\Settings and find system.xml,
• Open system.xml with a text editor and search for "windowed" and make sure is set to 1:
  <windowed value="1" />
  
• Now RDR2 should launch in windowed mode solving the black screen problem.

Hope this will help you

PS: You can go full screen with no problem, just remember to go in windowed mode before close the game!
