Thanks alpha-bravo. That solved the problem. For those afraid to install the unstable build, you don't have to. The installer (.exe) is just a form of ZIP file. So, just open the installer with a zip manager (I use Bandizip), and navigate to the folder $2\Bin64\Plugins inside the .exe and voilá, there is the TrackIR_rF2_Plugin_x64.dll. Copy it to your Plugins folder in the game and you're set. Only thing I noticed is that it takes a while to be initialized once the game is launched (almost 10 seconds), but I guess this is the normal time required to activate the plugins. Cheers.
Copy it to the Plugins folder in the game? Which ONE?? There are THREE folders called "Plugins" in the game install folder! 1.) C:\Program Files (x86)\rFactor2\Bin32\Plugins 2.) C:\Program Files (x86)\rFactor2\Bin64\Plugins 3.) C:\Program Files (x86)\rFactor2\Launcher\Plugins The TrackIR_rF2_Plugin_x64.dll was already in the Bin64\Plugins folder after installing the game, so I copied it to both of the other locations and TrackIR still doesn't work in build 798. What other Plugins folder is there?
