Doesn’t really look like it, the cornel box is a really good example. Here’s what that project produces:

Here’s what path-traced cornel box looks like (excuse poor modelling skills):

You can see 2 immediate points: color bleeding, soft shadows.

The image produced by “ray-tracing-renderer” has very sharp shadows and minimal color bleeding. I don’t know if it’s a result of their scene setup though, you can setup some gnarly looking light rigs 😃

maybe result of biased sampling.
