Default Fixed! (Well, somewhat...)

So, here's what I ended up doing:

I am on 4.4.2, rooted.

I unistalled SetCPU, and installed the "Trickster MOD Kernel Settings" app (Google Play: )

In Trickster MOD, I did the following:
  1. Under the General menu, I set the governor to "Interactive".

  2. Under the Specific Menu, I changed the following:
    • Temperature Throttle = On (default is OFF)
    • GPU Governor = On Demand or Performance (either one seemed to work, default is On Demand)
    • GPU Max Frequency = 400 (default on mine was 320 for some reason)

Once you set everything up, reboot the tablet.

Recall that in the beginning, with no tweaks, I was scoring around 16000 in Antutu Benchmark.

With these minor tweaks, I've benchmarked it several times and now consistently score between 21000 to 22000 in Antutu.
