Q:   After I installed HiAlgoBoost nothing happened... Is it possible that only DX9 mode is supported?

A:   Yes, only DirectX 9 mode is supported for now.

Below is the contents of hialgo_readme.txt from the installation package for HiAlgoBoost v2.4 for FarCry3, Apr-02-2013

HiAlgoBoost Ver.2.4   Apr-02-2013

WHAT IS "DEMO MODE"

In demo mode HiAlgoBoost will be active for 15 minutes, then it will be switched off.
After the 15 minutes - pressing F10 will re-activate HiAlgoBoost for only 1 minute each time.
To have another 15 minutes of playing with HiAlgoBoost, you need to restart the game.

TROUBLESHOOTING

*) If you get an error saying something like "Cannot find d3dx9_43.dll",
install the latest DirectX from here:

http://www.microsoft.com/download/en/details.aspx?id=35

or from here (whatever works for you):

http://www.microsoft.com/en-us/download/details.aspx?id=8109

Do it even if you have later versions - DirectX10 or DirectX11!

*) Also, you probably should install the latest display driver:

Start -> Run -> devmgmt.msc -> "Display adaptors" ->
*your display adaptor* -> Right Click -> "Update Driver Software" ->
Search Automatically...

TROUBLESHOOTING CRASHES

Ok, lets try these simple things if anyone is experiencing crashes:
1) Reboot.
2) Uninstall hialgoboost (Control Panel-->Programs and Features) and then install again
3) Disable overlays and monitors.
4) Verify game integrity by playin in online mode.
5) Update to latest DirectX and display drivers
6) Disable graphic control panel "enforcements" - set as much to "application settings"

Enjoy,
