No need for vulgarity, alpin.
But yeah, 1080p@60fps isn't going to work well, for quite a number of reasons.
-Massive encoding requirements (Few CPUs today will be able to cope with encoding this res and framerate in real-time at any quality worth watching)
-Massive upstream requirements (which exceed Twitch's capabilities to ingest)
-Massive downstream requirements (many viewers won't want to devote ~10mbps just to watching a livestream)
-Flashplayer sucks (it can't deal with the compute requirements to decode the mass of data needed, on most common current systems)
1080@30, or 720@60 are the viable options.
So yeah, step it down a notch, manage the expectations as far as what is currently technically feasible.
