Graphics Card Upgrade Hurting Performance?

[A Random Shrub]

For Christmas, I received a ton of computer parts to make a new system, which I am very happy about. One of these parts was an AMD Radeon R9 390. The card dominates all of the games I play, such as PAYDAY2, Grand Theft Auto V, and Fallout 4. Today, I decided to play Minecraft, something I rarely do. I was exited to see how the new system ran compared to my other.

The first thing I did was open a superflat world to test performance. I was immediately hit with a wall of lag. The framerate fluctuates constantly, ranging from as low as 20 up to 63. No matter what the framerate is, I have screen tear, even when it is below 60. Messing with vSync changed nothing.

I turned all of the settings to the lowest possible and shut off vsync. The framerate continued to fluctuate between 60 and 200.

With my other computer, I would be getting over 1000fps with the settings on a superflat world.

The Problem

I viewed task manager and MSI Afterburner. Sure enough, when I'm running the game, the graphics card usage stays below 40% and the temperature stays at idle. I tried dedicating 10 whole gigs of RAM to the game. Nothing changed. I am quite certain that this isn't normal, especially because my new system is better in every way than the old one.

Minecraft having troubles with hifh end hardware is not new. Btw when you replace your older 660 with 390 did you do clean driver uninstallation with DDU?

And screen tear still happen even if the frame rates are below monitor refresh rates. Just that usually the screen tear is more visible when FPS go above monitor refresh rates. To completely eliminate screen tear you need to use vsync. No way around it. Or using those Gsync/Freesync monitors.
