1. Is it possible to skip the intro videos? And if not, can I at least remove or lower the sound?
2. Is it possible to remove the camera tilting while strafing? I just find it confusing.

1. Navigate to "RAGE" in your Steam games list. Right-click it and select "Properties". Click the "Set Launch Options" button. A new window will pop up with a text field where you write the following (without quotation marks): "+set com_skipIntroVideo 1"

2. There was a command for that too, but it has been disabled by the patch.

Thanks! Damn shame they disabled that, but I guess it was an advantage and I'll get used to this tilting.
