For the most important functions I do use the joystick and the Saitek
Quadrant. For the rest I lift the headset to look below to the keyboard.
But believe me this is all very expensive, forget all the crazy readings about my i7-2600k GTX1060-3gb can run BoX in VR, not true, it needs “top of the line” hardware.
My i7-7700k GTX1080 and even the DDR4 had to be overclocked to keep the BoX game smooth. For a decent level of playing BoX, you need an 5ghz CPU, GTX1080ti or RTX2080 and 3200mhz RAM as an good starting point. BTW, for BoX in VR you can not use nVidia SLI mode.
Pimax 5k seems to be the best VRset, but for VR starters only I would wait what HTC, Valve and XTAL is going to release.
Once try realVR in a flysim and you will never going back. For most here TrackIR was an eyeopener, but I compare realVR more to my first joystick (MS-FFB gameport) or the Voodoo Vcard for RB3d. That feeling!
Just feel in vr how small the Macchi 202 cockpit is, move the canopy put your head out of the cockpit and hear the wind/see the exhaust, feeling your stomach while making a to sharp manoeuvre and at last the real 3d cockpit. You are now entering in a real flight.
