Its Kind of essentiel not to have windows bloated with processes in the background when gaming.
Only have running what is nesseary. ( look in task manager) Removee or disable ALL updaters, bloat ware crap etc.....
Disable devices that are not needed (by script or device manager or bios) wifi, bluetooth, webcam, cd rom drive :-) .....
Un-plug usb devices not needed when gaming
If you have both usb2 and usb3 portts : Use USB 2 ports for mouse & keyboard. Some pcs gaming experience can be better if they not share same usb bus.
Yes it was nice back in the days and became crap when Razer had it. But now Im using it again on both my win 7 and 10
