Path tracing is inherently a lot more computationally expensive than precomputing stuff, so V-Ray RT will always be at a disadvantage. And not everyone needs raytracing precision for walk-throughs anyways. Btw we can actually get 20-30 fps on a VCA right now for a 1280x720 image, but it’s terribly expensive hardware.

Best regards,
