Hey there,

So i finally got into Black Flag after a year of figuring out why the game crashed on launch but then after I fixed it, it then gives me around 20 FPS on the very first singleplayer mission. (when looking back I get 60 FPS)

  1. I have tried playing with the settings from high to low then custom change around but nothing seems to happen (V-sync doesn't seem to affect anything either)
  2. I happened on the very first mission, cutscene was also a tad laggy.
  3. Happens on every launch.
  4. I have not found any troubleshooting that would fit my needs.
  5. OS: Windows 10 Pro 64-bit (10.0, Build 19042).
    CPU: Intel Core i9 9900K 3.6 GHz (8 cores).
    RAM: 32 GB.
    GPU: NVIDIA GeForce RTX 2080.
  6. Insane Lagg & Ingame Settings
  7. Was trying to make a support ticket for this but seems they have closed it currently.



What I did to fix my game (because it didn't open when launching and been in a talk, back and forth with Ubisoft Support about this matter)

So I went on a Steam forum thing and this person wrote this:

- Go to your Assassins Creed 4 Black Flag game folder (Steam\Steamapps\Common\Assassins Creed IV Black Flag)
- Right click AC4BFSP.exe
- Select Properties
- Select Compatibility
- Under "Run this program in compatibility mode for"
- Choose "Windows 95"
- If running it in Windows 95 compatibility mode doesn't work, other users have reported success selecting a different option from the list.

(Which fixed my game but now lags (I dunno if these settings have something to do with that)
