The SteelSeries Engine, which is also used to customize the keys on the SteelSeries Shift keyboard, allows you to custom macro any button on the Sensei, something most mice don't allow. You may use a "burst click" for the left mouse button to have a single left click function as 2 or 3 clicks, perfect for burst firing.
The Sensei becomes the star of the show when its settings come into play. We see that there are two selectable DPI settings which can be quickly switched with the DPI selector button. The illumination colors can also be changed independently from one another, and choosing from one of the 16.8 million colors leaves plenty of options open. The CPI 1 and CPI 2 settings are the color of the CPI LED for each of the two settings. There are also options for the LCD, and then the DPI fine-tuning options, which we will spend a considerable amount of time on.
The FreeMove setting changes the amount of directional correction the mouse uses to correct for poor surfaces the mouse might be used on. The ExactAccel allows variable acceleration levels for when the mouse is moved faster, and on the other hand, the ExactAim allows a "negative acceleration" for reduced sensitivity for fine-tuned movements, perfect for snipers or low-sensitivity situations in RPGs where precision is key. The ExactLift allows adjusting how far off the mousing surface the Sensei can be before the its signals are "ignored." The fine-tuned settings allow you to exactly dictate how your mouse will respond in any number of situations, we'll explain the beauty of this on the next page in the "Testing" section.
We also wanted to check that the polling rate set on the SteelSeries Engine software is what is actually seen.
As we can see, our 1000Hz setting was what was actually measured, and confirms SteelSeries' claims, and the Sensei achieves a very high 1000Hz polling rate.
