High Fidelity Unity VR Development on VisionOS Specs Recommendations

As you may know, it’s mandatory to use an Apple Silicon chip to build apps on VisionOS. i’ve been a game/vr developer for a few years now, and i’ve never touched an Apple device since. I searched for quite a few hours to have some feedback especially on the power needed to dev High Fidelity apps. I wonder if you have any recommendations. Do I have to take the maxed-out specs Apple M4 max (because of the stronger GPU) ? Or is the M4/M3 pro can be sufficient ?
