OSX has an annoying feature called "BeamSync", which on later versions of OSX is always on. For whatever reason, Apple devs decided to force this feature to always be on, so applications must always render with v-sync regardless of what they set their swap interval to. This issue would cause syncing to the vertical refresh for each additional active display, and wouldn't allow rendering above the current refresh rate. This caused major rendering stalls and prevented video frame timing from being accurate. This fixes the issue by using an undocumented set of functions to disable BeamSync. Note that because this is an undocumented method of working around the issue, its existence cannot be guaranteed. If the functions no longer exist for whatever reason, it will safely do nothing.
