Computer specs -

  • i5-3570 Quad Core 3,4 GHz
  • 8 GB DDR3 RAM
  • RX 480 8 GB Reference card
  • Windows 10


So, when I had my old graphics card, GTX 650 Ti with 2 GB VRAM, I had no problems running the game on highest settings at 60 FPS, now after installing the RX 480, I seem to have all those problems listed above. Apparently the graphics card isn't recognizing a java application (Minecraft) to be a game and therefore not utilizing all it's power as you can see from the screenshots.



The orange line is the current clock speed, and as you can see, it's fluctuating, not holding at full clock speed of 1266 MHz. Not even the fan noise and the temperature (only slightly) has increased even though it always does when I am running any other game. (Minecraft ~ 50C, Overwatch ~ 77C)



These are my current WattMan settings (I undervolted it and made sure it doesn't throttle)



These are my global settings.
