Well, I have been working on ray-tracer for a while and yes it is beyond the scope of todays computers(higher resolutions). Ray-tracing gives some nice things like mirrors 'for free' but in balance theres stuff you really can't do with ray-tracing without very expensive algorithms(antialiasing for example).
The main things that make ray-tracing expensive are resolution and how long you trace each ray.
