I wonder if this 'Game Mode' will stop W10 from constantly performing all manner of activity in the background when I'm trying to do stuff, which at times causes things to grind to a halt. Example, was playing EVE the other night and W10 decided that that would be a good time to run something called Compatelrunner.exe, this despite me having edited the relevant entries in Task Scheduler to prevent this rubbish from running. That's just one example, currently it's decided to download an update, right in the middle of me enjoying another game. Had to quit and am now waiting for the update to download. And don't get me started on how ******* long W10 takes to download a ******* update.
