Hi Rayzex
Over time I have compiled a list of possible fixes for these mouse issues. Not sure what you have tried - check through the list here:
(1) In the mouse software lower “Polling Rate” to 100 - 125 range.
(2) If you have Razer Synapse software check that the Razer “Stats” software is not enabled. Open Synapse - along top bar is “Stats”. Open that - if enabled - disable “Data Tracking” in the Stat’s settings.
(3) Try disabling Foreground FPS limiter on Menu > System > Advanced.
(4) If you have a Wacom device you might disable things there or temporarily uninstall the Wacom drivers to test.
(5) Enable the rawMouse CVar. Open a chat box then copy/paste this line. Ctrl + V will paste it.
/script SetCVar(“rawMouseEnable”, 1);
To check that the script worked go to the Wow folder > WTF - look for the Config file. Open with notepad. This should be at the bottom of CVar list:
SET rawMouseEnable “1” (0 - zero is off)
(6) On Battle.net App under “Options” Go to Game Settings > General - scroll down then check that Hardware Acceleration is enabled.
(7) *(The settings below are a Windows 10 feature - they have proven to be problematic - you would want to make the changes to avoid other issues as well)
Navigate to the main Wow folder. Down near the bottom of the list is the Wow icon (W) icon.
Right click on the Wow icon. Select “Properties” at bottom of list. Then select “Compatibility” tab along top of next pane.
At the bottom of that select (check) “Disable Fullscreen Optimization”
(8) Disable NVidia Share then close Geforce Experience
