30fps just IS stuttery in VR, I can’t understand anyone who thinks otherwise. They either have some disability in perception or have never seen better lol.
In the G2 specifically, 45fps (locked via Rivatuner) is incomparably better. It can actually feel very smooth, more than you would expect (something to do with it being exactly half the refresh rate, though I didn’t observe this effect in the Pico4) .
So try and tune your settings to hit 45fps locked, it will surprise you!
