So a couple days ago I was playing some Minecraft when suddenly I got a huge drop in FPS that simply didn't go away. It persisted in other games, so I checked out the Windows Experience Index and it said something like "new hardware has been added," so I retested it and got new results. Both Graphics and Gaming graphics had a 7.3 before this whole thing.
What's the problem here? I was getting pretty consistent performance until this sudden drop occurred.
