Flawless Widescreen was created in an effort to make it easier to craft fixes and patches to get games functioning correctly in UltraWide/Surround/Eyefinity gaming resolutions, often developers neglect these types of users leaving them to fend for themselves and find their own solutions, or in some unfortunate cases - live without the wonderful world of ultra-wide support.
With simplicity in mind, designed to be as simple as possible to use - simply select a supported game from the list, configure any basic desired configurable options and launch your game.
