anyone heard of this? BS or useful?
short story --
Cryogenic Treated Rotors
For drivers who need something even tougher than a standard StopTech® Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo® rotors.
Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 º F, then gradually brings them up to over +300º F, and finally back to room temperature. This conditioning of the rotor improves its service life, especially in fleet and emergency vehicle applications.

Probably none because it doesn't increase hardness. It is claimed to increase the uniformity of hardness, which translates to "they'd be less likely to warp but more likely to crack under high stress", like in a track environment.

There are no internationally recognized engineering testing methods to validate any claims made by "cryogenic treating" steel. Further, the international standard bodies do not even have standardized procedures to cover this. Heat treatment is the only hardening treatment recognized currently. Everything else is marketing speak.
Not to say that the may not pan out to be valid, they just haven't been tested and validated yet. Doing a quick google search yields a lot of information from proponents of the treatment (vendors, manufacturers, etc) and all point to one conclusion "we don't how or why it works, we just know it does and we can't release our test results to conclusively prove that it does".
Here the patent info if you are so inclined:

Definetly works for me. Got my new oem rotors treated for my Porsche at Porterfield Brakes in CostaMesa CA. (Founder died last year so process may not be available) Already have twice as many miles & half the wear as my original rotors. When my IS350 needs rotors I will have them treated before install.
