Keyboard input lag

[des]

Hello sometimes I have delay problems with the keyboard, these are the settings:

Rainbow you are siege
Mechanical keyboard Acgam
Use mapping 2: shift (l3 for run) q (l3 for tilt left) and middle mouse (r3 for melee) and (r3 for tilt right).
I made a factory reset and redo the mapping but I still have the problem sometimes.
What do you think about it?
Thanks

have you tried other keyboards or mapped these buttons to your mouse,
and then do a comparison?

some keyboard can be set with driver from the producer.
we are not sure settings in your keyboard should be changed or not.
