Lenovo Explorer. I don’t play VR games really, but it’s fun when my little nephews visit (the A770 handles simple games like Beat Saber well). Outer Wilds in VR seemed like a good time to dust of the headset but it’s a bit too stuttery. I didn’t look for any type of fix or optimization though.
But if you’re serious about VR gaming Intel Arc is not a good idea for now. However on /r/intelarc some report good results, saying it varies from game to game.
