I have run skyrim for a long time with little problem , I even have a nvidia geforce 970 graphics and a intel I5 basic hardware.
My keyboard is the k800 Logitech but I've tried another key keyboard and mouse with and get same results.
When I execute skyrim it runs ok but if I go into console mode I notice the keyboard response time is so slow. I can type player.additem
and 2 minutes pass before it completes. Odd thing is if I exit skyrim the keyboard is still slow... so I am forced to reboot.
This has only been since I upgraded to windows 10.
