No all it does is use a coprocessor which is designed for this process in the first place, and now generates the key internally on the TESC, rather than doing it via bootloader.Edit: normally keys are generated and sent to the TESC which is a nvidia coprocessor that usually deals with this sort of stuff (and also hasn't been hacked because it's very fucking secure) .What's changed is that now one of those keys is done in the TESC itself so you can't see the key that tells the switch to carry on and boot up.0 performance loss.
