ELSA wouldn't touch the drivers with a ten-foot pole. The NVIDIA reference drivers are more than adequate. You still can't help but miss the additional features that the competition use to try to make themselves stand out from the crowd. In spite, or perhaps because of this, the overclocking tool activated using the tweak function (see image) is of interest.
Hint: Only those driver extensions have been published that aren't already available as part of the NVIDIA reference driver. Anyone unfamiliar with the reference driver can find screenshots here .
