 From my understanding of GSYNC, the monitor refresh rate will be 
completely slaved to the GPU rendering (frame) rate. No need to 
wait/sync on vblanks, as the monitor will scanout the buffer when it 
ready (presented). I will start thinking about implications this could 
have on the protocol we're devising atm, but I guess all in all, GSYN 
will just going to make everything even simpler.. tho I'm not sure it'd 
change anything protocol-wise.
