Very Low FPS while in game, High FPS if game is running in background

I have done everything that is suggested to raise frame rate, which while in game sits at about 4 FPS.  While in my two monitor set up with F3 up, I clicked into my second screen to open Google and the frame rate jumped up to 100 FPS. 

I have no clue what is wrong, it happens with multiple versions, with the lowest setting for graphics that I could in game, my computer falls will within the requirement for Minecraft. All of my drivers are up to date, I have redownloaded Minecraft, updated my computer.  

Other games work perfectly fine, it seems that the problem is only with Minecraft.
