A simple command line utitly to patch existing x64 executables to include the
export symbols NvOptimusEnablement and AmdPowerXpressRequestHighPerformance
as required to enable the discreet GPU on some machines (mainly laptops)
Originally written to be used with the game Sector's Edge it should work with any x64 Windows application.
At this stage, this project should be considered experimental - I've only just got it working and have only done some very basic testing. I'm keen to hear how it works for others.
If you find problems or have suggestions, please log an issue
