Notes
Use this trick to activate a borderless fullscreen windowed mode. This method works on both AMD/ATI and NVIDIA cards. (Tested on both)
Press and hold Alt+Tab ↹, release only Tab ↹, then while holding Alt click with the left or right mouse button.
The game will refuse to run when installed on a drive which is managed by a Storage Space on Windows 8 and later.
Sometimes the game might appear to be frozen, but you can still hear the sound and the HUD works.[5]
This is caused by lack of triple buffering in the game.
Don't force VSync in D3DOverrider, only triple buffering. Enable VSync in game options (or force it in NVIDIA control panel or NVIDIA Inspector). If you're using SweetFX or another injector, it probably won't work (use workaround below).
Download and install RadeonPro, Launch RadeonPro, Add a profile pointing to AC4BFSP.exe or AC4BFMP.exe, Select the exe profile by clicking on it, Go to the tweaks tab leave vsync to driver default and check triple buffering. Tested on Win8.1 with CFX 7970s
This method was actually only tested on Windows 7 SP1, on a PC equipped with an NVIDIA graphics card, and Windows 10 with an AMD graphics card. Press Ctrl-Alt-Del, then click the cancel button (or use your Escape key) to return to your desktop, then go back to your game by clicking its icon on the taskbar. DO NOT use Alt-Tab because it won't work. This workaround makes possible the use of SweetFX or other injectors with triple buffering.
