Be aware that if you just cap your FPS to 30, you can have a problem wich is the same as microstutters: it's call frame pacing. Like you, i love constant smooth flight, without FPS drop or stutters. Only solution i've found, enabled adaptative v-sync (half refresh rate), my screen is 60Hz, so this option cap at 30Hz @ 30FPS. A bit of input lag, but i can deal with this.
