The force_filter.txt controls at what distance and to what degree we filter the output.
More filtering results in a steadier cursor but a side effect is more latency (a more laggy cursor). Lower filtering will produce a more crisp low latency responsive cursor but if you have any interference it will become more pronounced. Additionally if you're not a steady hand this will become more apparent.
If you're playing competitively you may want to consider changing to a more lean filter file. The one attached I use in League of Legends and I feel no latency on my cursor, I personally will not play competitively without a customized filter file.
EDIT: I've lowered the filter again by about 20% download it if you're in a good environment. Backup your old one in case this one is too lean for you.
Follow these instructions to change your force_filter.txt:
1. Navigate to your Hydra directory. (Default C:\Program Files\Razer\Hydra\)
2. Back up your default force_filter.txt by making a New Folder and dragging it in.
3. Download the force_filter.txt attached to this post to the Hydra directory.
4. Close the Razer Configurator by right clicking and closing in the tray, and closing any other Razer window that may be open.
5. Run the Configurator again by going to the Start Menu> All Programs> Razer> Razer Hydra> Razer Hydra Configurator.
6. Enjoy lower latency. Swap back to the old one if you're getting an unstable cursor.
