Yea, you need to bind it, but it should stay bound once you bind it one time. Then again, it's assetto we're talking about, default launcher is a tremendous turd and iirc it resets your bindings on every registered change in input devices, so i can't promise even that. Do bindings, it's not much of work, you just set a small handful of things. 

Also, try Content Manager. It installs shader patch for you (massive improvements in many, many ways, weather, night, day, optimizations), and most importantly it's a fully competent launcher that doesn't suck like hell. It's free, too.
