The Oculus/Meta Quest 2 runs on a Qualcomm Snapdragon XR2. That chip's GPU, the Adreno 650, has a pixel fill rate of 14 GP/s. Compare this to a GPU like the NVidia RTX 3090, which has a fill rate of 190 GP/s.

Lighting, textures, transparency, and many of the effects that make things look good in modern games, at the resolution and framerate required for smooth VR, can't currently be done on a $400 headset.

At least in terms of the cartoonish graphics, it seems to me like a case of "fast, cheap, good, pick two".
