Is it possible to toggle your aim in this game? I hate holding down my right click to zoom in. A mouse isn't a controller. It is so much more comfortable to click the zoom once. Any help would be appreciated.

There's no option for this currently in the game. I had the same issue at first but I got used to holding down the RMB to ADS. Now I switched to that style on all of the FPS games I play. Not sure if this will work for RAGE, but someone wrote this for BFBC2:

Also, check the Steam User forums, someone else posted the same question. There might be a key binding you can enable i the console or on startup (if you enable the console, through, you won't be able to get any achievements).

Borderlands had the same problem, but at least there was a fix for it in the CFG file. This is frustrating.

A long time ago I got used to binding ironsights to space and jump to some other key. That way it doesn't impact my aim or movement, and it works for all games.
