Stop Filtering The Trigger Axis Value
The trigger axis value is filtered, meaning that controllers do not properly register rapid trigger pulls.
This is not a controller issue but a software issue. It means that games that require you to pull the trigger as fast as possible do not work properly as they are not receiving raw input data.
According to people who have looked into it this is done to smooth the finger tracking in the Oculus Home. This is not worth the gameplay ramifications.
Remove the trigger filtering.
