I have downloaded the Win10 Upgrade through there executable and upgraded just like normal. I like the new look of some things, especially Windows Defender. Now I'm a gamer and I like my graphics, so when I had been experiencing major frame drops and my GPU utilization was below 50% I figured there was something wrong. Now before the upgrade just on win10 home edition I ran this game at full blown graphics, and after I had changed all of them to the lowest possible and the problem still arose. Recently I had just needed to end a process via Task Manager and I often scroll down when I see something flag red on its utilization. This was my CPU maxed at 100%. (I don't have the greatest processer in the world but it didn't have problems like this before) So upon scrolling down I had noticed that down in the windows processes there was something taking up a whopping 40% on average. Now I had turned this off and then went back to the game and my GPU was being able to utilize 90% and I had my frames back. I like that Microsoft dusted off windows defender and put some polish on it. but I do not like how they made it so needy and assertive. " we'll turn this back on automatically" I like how they make a failsafe to prevent people from forgetting they have it off, BUT how could you forget when it sends you a notification every time you turn boot up your computer. I just wish we had some control if we want it on or not because its very demanding on my system. If anyone has heard of any news relating this I would appreciate to hear it.
