With Assassin’s Creed 3 now out on Steam, the Crash Wiki team has built a guide to help thousands of PC gamers worldwide overcome the most annoying bugs, crashes, errors, DLL problems, poor FPS performance and more. Read on and let us know your thoughts in the comments section after the post.
Assassin’s Creed 3 Fixes for Crashes, AC3SP.exe stopped working, Poor FPS, UPlay stuck, DLL Errors, CD Key Invalid, No Sound
AC3SP.exe stopped working
Try one or more of the following:
Go into the Steam folder /steamapps/common/assassinscreed3 and find the two exe files. Right click properties and then check the run as admin.
In your graphics settings, turn FXAA off. This usually solves it for nVidia users.
For Windows 7 users: type %temp% into the search bar in the start-up menu and delete the temp folder.
So one way the game can crash is if your save file is corrupted. If you delete your save file and disable automatic cloud save sync in Uplay, the game will be able to run without crashing. (TO BE SAFE, MOVE/COPY YOUR SAVE FILES FIRST BEFORE DELETING THEM)
Save files for AC3 are located in:
“C:Program Files (x86)UbisoftUbisoft Game Launchersavegames[folder name that is probably related to your account]54”
Let us know if this fixes the issue.
Can’t Connect to Multiplayer
It’s highly possible that the servers are down at the moment, so be patient. If you’ve confirmed the servers are up, make sure your anti-virus program is not blocking AC3. Or just shut it off while you’re playing.
Low or Poor FPS
Turn off Vsync directly in your config file. In your documents folder, open up the Assassin’s Creed 3 Folder. In there should be an .ini file named Assassin3. Open that file up in notepad, and find the line which says “VSync=1”, and change the “1” to a “0”. Then save the file.
You should also try turning off FXAA in the same ini file.
