0.00001 fps !!

Unless your code is extremely severely and totally optimized !! B

But in certain cases, you can do it nearly
realtime (say 15-20fps and even 30fps), but you must limit
the number of effects, the raytracing depth to 1 or 2 and
no antialiasing at all !!!

It depends on the scene, the number/kind of effects and the raytracer itself.
You will find more informations about it with the search function and at www.openrt.de .

real time ray tracing (and other types of software rendering) tutorials

If you use DirectDraw to pump the software render into Video Memory you can expect about 30FPS max just because nVidia and ATi drivers don't play well with DirectDraw for some reason. Turning off hardware acceleration through dxdiag actually increases the framerate. OpenGL doesn't provide direct access to video memory so the results are even worse.

Probably the best looking real time ray tracing engine out there. You'll need an SSE2 enabled processor to try it out.

Wolfenstein 3D and Doom use "Ray-Casting" not exactly "Ray-Tracing". Ray Casting is a subset of ray tracing, it is faster because it uses geometric contraints (walls and floor are always perpendicular).
