I just uprgaded to W10 recently, and discovered very annoying problem. Since I work with modding some games, I have to alt-tab a lot, from full screen to desktop. In W7 it was taking like 1 second to alt-tab to deskop, but on W10 it is like 4-5 seconds, and I hate losing this time, it feels like 5 times longer. Is this normal, is my PC spec to slow for W10 + alt-tam games? I don't mention any particular game, because I tried many of them, and it happens on them all, old games, new games, same thing...

My drivers are up to date.

Please advice something, I still have 5 days to revert to W7 then it will be too late.
