Disabling the Forza Motorsport intro video is a pretty easy process.

1. Open your game installation folder.


You should now be in the "\steamapps\common\Forza Motorsport\" folder.


2. Navigate to the "\steamapps\common\Forza Motorsport\media\base\ui\videos\" folder. It should contain a "1080" folder and a "2160" folder.


3. Inside the "1080" folder, locate the file named "logoparade.bk2"


4. Rename this file to anything else. In my case, I just added "renamed_" before the file name.


5. Repeat steps 3 and 4 in the "2160" folder.

And you should be done! Enjoy the sweet quiet next time you open the game!

If for whatever reason you want to undo this, just rename the files back to "logoparade.bk2"
