How to lower input delay in Fortnite

Here is the place to go in reg edit:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options
What each number means in reg edit
1 Idle
2 Normal (default)
3 High (Easier to run then real time but still is better than normal)
4 RealTime (lowest delay but taxing on low end cpu)
