If you are using Wi-Fi or powerline, please test Haste with an Ethernet connection. Wi-Fi environments are often unreliable for gaming because of congestion and interference. Powerline environments are often unstable due to poor electrical wiring. If Haste does not perform better once you switch to an Ethernet connection and you would like us to review your experience, please email us at support@haste.net.
Also, please review the “best practices” for performance we've included at this article.
