So, I used to get 200+ FPS on minecraft, but then one day i tried to open it, and got an error code "The application was unable to start correctly (0x0000005). Click OK to close the application." I then uninstalled Minecraft, as it kept doing this, and reinstalled it, I then opened it, then I was getting 2-35 FPS. I uninstalled again, and got 100ish FPS, but the frames were very choppy and laggy, even though it was showing 100 FPS. I have tried playing CSGO, and other games, and still get 100+ FPS and no lag. Help?
