From Omega Corner website:
ABOUT THE OMEGA DRIVERS AND THIS SITE:
The purpose of the Omega Drivers is to provide gamers with an alternate set of drivers, ones that have more options and features than the original sets. The drivers contain optimizations, extra features (like OC capabilities), more resolutions and internal tweaks that can give them the edge in a gaming enviroment over the normal drivers, which are often tailored for synthetic benchmarks. All Omega driver sets are tested (unless noted) by myself in my own PC or in an alternate PC (in the case of the nvidia drivers) to ensure maximum compatibility and reliability.
