I have installed WIN10 on my very old HP some time ago and generally it works well.

However using Edge there is a problem with a time lag between making a keystroke and it appearing on the screen or just not being registered.

It seems to be related to the speed of typing. No problem with running IE11 with compatability setting on for this forum. Compatability setting is necessary or I cannot get "quotes"

I have looked at the WIN 10 forums but there doesn't seem to be an answer.
I might add that Microsoft did say my video card was too old for WIN 10 but it works fine for everything else.
Any ideas? like some settings fix?
