The 60 FPM limit is probably because the diver is syncing to the vblank signal
from the monitor. For most LCD type monitors with will either be 60Hz or
120Hz. For the nvidia X11 drivers you can turn sync to vblank on and off. I
generally have mine on since there is no reason to have the video card produce
a frame rate higher than the monitor refresh rate. I don't know if this is
configurable in the OS/X video drivers.

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense..
