Whoa... Pretty good for me... Because, the one and only time I used Luxrender, OMG! So many hotspots! Probably, you have lesser hotspots... I prefer Cycles...

Boi i rendered it for just 7 min. Try Cycles and you won't even see the ball properly. It's kinda unoptimised for CPU rendering

I can. But be warned, this will take much, much longer to render in Cycles. You won't even something that looks like caustics till you hit 4096 samples.

I can really accept that fact. I also feel cycles helpless with glass and glossy shaders. But, I once when I tried caustics, it was okay... Let me try this once, and please, I'll make it myself.. I don't need your project...(Just an attempt)

[EDIT]: I tried it using Cycles, I found that it was less noisy, but couldn't get that light path travelling through the sphere...

Alright. IOR of the ball is 1.4. Plane is 100% diffuse. Also, I'm using volumetric scattering (the reason why there is so much noise)

I just rendered this with cycles... Couldn't get the light path through the sphere though.

You forgot using volumetric  and transmission bounces. Also, I rendered mine using an i3 processor

My processor is even older, intel Core 2 Quad: 2.5GHz - 2.5GHz
OMG, I forgot, but anyways, I can't do it now, I'm doing my homework...(#LastMinuteHomeWork)

boi that would only take me less than 7 minutes to render in cycles. mainly because of the 4 GPUs I have in this system.
Edit: looks like I'm right but in order for it to not look too noisy I would have to render it at a very high sample count which could take around 12-20 minutes.
