Once you have installed the Unoffical Patch ensure you have added the Steam launch options as below, so that you can easily lauch the patched version of the game from your Steam library:

- right click on the game in your Steam library
- select Properties
- on the General tab, click "SET LAUNCH OPTIONS..."
- type in: -game Unofficial_Patch
- then hit "OK"

Once you have done that navigate to the install location for the game (...\Steam\SteamApps\common\Vampire The Masquerade - Bloodlines):
- right click on Vampire.exe and select Properties
- click on the "Compatability" tab
- Tick "run this program in compatability mode for:" and select "Windows Xp (Service Pack 3)"
- Tick "run this program as administrator"
- Click Apply then Ok
- Run the game



After that Steam should show you as running the game in your Friends list and therefore track your hours :) Hope this helps someone!

NOTE: Only works when launching the game through the Steam library, Steam will not detect the game running, and won't count hours, if you use the desktop shortcut created when installing the patch to launch the game. At least for me anyway.

Have fun playing this great game!!
