Input Lag on razer Deathadder Elite

Post by Inventing » 19 Mar 2019, 14:55

Hello everyone,

Around a week ago I purchased a Razer Deathadder elite and was very pleased with it. It had a low response time, and was much faster than any other mouse I had ever used, and everything was fine. However, after I went a couple days without using it, when I plugged it back into my computer, I found that it suddenly had much higher input lag than what it had before, going from what I estimate was around 1-2ms to 8-10ms, which is very noticeable. I have a Dell XPS 15 9570, which has a 60 hertz display, and typically can run games at over 100 fps. I know this is not a monitor related question, but I have spent at least 12 hours over the past 2 days researching and attempting to fix this issue without any success. Is there anyone with any ideas on what I can do to fix it, or any personal experience with the Dell XPS 15 9570 having similar issues? Is it a problem with the mouse, or the computer? Any help is appreciated!

Before going further, I've seen some things fix mouse lag
1. Full reboot (complete power off to cold) -- reboots everything
2. Full unplug of mouse (complete unplug) -- reboots mouse electronics
3. Make sure Zowie drivers are used, not Microsoft default drivers.
4. Try other USB ports -- reinitializes

Also, check for red herring effects (such as introduction of mixed-Hz multimonitor ). Sometimes the mouse will lag as much as the lower-Hz monitor on the high-Hz monitor, when some screen activity is occuring on the low-Hz monitor. This normally should not happen but I've seen this repeatedly happen, in some buggy situations.

Also, make sure poll rate is 1000Hz (1ms) instead of 125Hz (8ms). Sometimes that requires the vendor drivers, not the Microsoft drivers.

I've also seen that sometimes when you uninstall the vendor drivers, the mouse (if still plugged in and powered) still stays at 1000Hz with the Microsoft drivers until your computer is power cycled, then it's back to just 125Hz on the next computer power up from cold boot. It does not always happen with all mice. So if you uninstalled several days ago and it worked fine for several days and then stopped working, this might be the possibility.

Also, don't share the same USB port cluster with an external disk drive or high-bandwidth USB, that can slow down the lag of your mouse -- if you added a large number of ultrahigh-bandwidth USB devices (e.g. disk array) you might want to consider a PCI-Express USB3 quad-port card to spread the bandwidth load around.
