We've heard the community and are pleased to say that we have been able to remedy the issue (identified in our Known Issues list yesterday) causing some PC versions of Far Cry 4 to go directly to a black screen due to the presence of external USB devices. Some have been able to temporarily fix this problem by disabling USB devices and certain drivers, but we realize this is in no way ideal. For that reason, next week we'll be releasing Patch 1.4.0 for PC that should remedy the problem and allow PC players to enjoy the game as normal.
Though Patch 1.4.0 will contain additional fixes on release, we wanted to let users know that the black screen issue has been tackled. An update containing the full list of fixes will be posted to the blog prior to the patch being released on Friday.
If you have any further concerns, please contact Customer Support.
Please Note: This is unrelated to the Game Update that some players were able to download earlier.
Update: November 21st, 3:30PM Due to a minor delay this patch may be pushed to sometime early next week. We apologize for the inconvenience, and will update you if we have a new ETA.
