When I first started mining I spent hours looking for the most optimal configuration files for xmr-stak-amd and xmr-stak-nvidia. It would have been nice to have a bit of a community built solely around sharing configuration examples.
Today I have launched XMRStak.com with the hopes that it will help others save time when trying to get the most out of their video cards.
The site is simple; You create a username and then are able to submit your AMD and Nvidia configuration examples for others to view and comment on. You are able to upload screenshots and embed videos. You can make your example as bare bones or detailed as you want.
