Haste does not guaranty lag reduction for all users but please make sure you review the following factors that may affect your circumstances.
First, ensure that your game is displayed in the status tab of Haste while the game is running. If it is not, then it is not a supported game being played on a North American server.
If you are encountering an error, please refer to this article.
Even if Haste is not improving a single ping measurement (i.e., latency), Haste also optimizes jitter and packet loss, so while your ping may not change, your jitter and packet loss could be improved. Your ping may decrease over time as Haste identifies better paths for your connection. If you would like us to review your experience, please email us at support@haste.net.
