So I just got a viper mini, previously I was using an old office mouse. Any tips to make the transition easier?
Can't do much more than just play. Let it be actual games or some aimlabs style games. I changed mouse like month ago and playing Apex Legends made me used to it because it has bunch of movement, tracking and precise aiming. Good combination to get used to new mice. Just need to use the mouse a lot and move around so games like Valorant may not be the best IMO.
Your old office mouse most likely had a polling rate of 250hz - if typical cheap office mouse... The Viper Mini can be set to 1000hz. In practise, a higher polling rate will smooth the game while also reducing the already minimal sensor latency (not to be confused with the m1/m2 click latency).
Instead of the standard sensor ring/rectangle, etc. type of glide surrounding the sensor, all Viper minis used to come with this stupid sensor ring that is part of the actual plastic bottom - case shell. Users, including myself, have reported that their viper mini did not feel smooth on the mouse pad, but rather extremely scratchy/draggy. The working solution for this is to cut that protruding rectangle off the bottom shell plate with some sharp DIY knife to flatten the area surrounding the sensor.
Another annoyance is that the Viper mini (VP) comes with a Pixart 3359. This sensor does not have your typical L/M/H LOD settings in the Synapse, but rather a padwise LOD settings that need to be calculated or whatever, which are not ideal in my opinion. However, I'm not sure about you, but I can't play on the VP's default high LOD. The working solution for this is to apply a piece of black tape that extends from the inner bottom wall of the sensor ring up to 8 millimetres in order to achieve your 1 millimetre LOD. Basically, you will be covering a lower plastic part of the sensor(or which is attached on the sensor tbc) to get your desired LOD... and there is only one setting which is low LOD from doing so.
I highly rate Viper mini and Deathadder mini as they both are extremely good, scoring 2.3ms and 2.1ms on the click latency chart ( https://www.rtings.com/mouse/tests/control/latency ) which is extremely low compared to any other mice, and their 8.5k dpi sensor is more than capable of producing some good results. However, if you have wider palms, you'll need to work your way around these two mice (VP in your case) to get a good grip because they can feel extremely small/light to control at times.
