I am using a wireless KB&M (Logitech K270) and everynow and then I get input lag. Sometimes it happens once and doesn't happen for hours and then sometimes I got to deal with it for 10mins turning it off and on to try to fix it.
I had the idea of buying another wireless KB&M and as soon as I used it I had input lag from the get go. For awhile it was my mouse everynow and then but now its mostly my keyboard and is quite frequent.
I have really ran out of idea's on how to fix this. It can happen when typing on here but happens ALOT when playing WoW.
I also have tried changing what USB port the receiver is in and it didn't help.
Any idea's would be great and by the way I am on windows 10 if that matters any.
