How to force high performance on HD 4600 iGPU

[Bubbleawsome]

As my 7970 recently died I've had to fall back onto iGPU. Most of my games work ok, except minecraft. In minecraft the iGPU falls from 1250Mhz to 600Mhz and the fps drops into the single digits. Power plans aren't doing anything, as they just dictate CPU core speed. Intel's drivers don't seem to do anything either.

Anyone had this problem and fixed it?

Have you tried at stock clocks for the CPU part?

Else you can try to OC the GPU part and see if that changes anything.

Seems you can OC it quite a bit. Maybe something you can use until you get replacement.

I've not gone to stock on the CPU. I might try that.
Sadly it looks like balla got an insane chip. Mine gets unstable at 1300Mhz. Ah well, so is overclocking.
