I have recently built this computer and I am getting lower FPS on minecraft than my last computer. My specs are FX-8350 with a R9 280x on my new pc. My old pc was an Intel Pentium 3.00GHz with a GeForce 6600. I was getting a constant 60 fps with my old pc but with my new one it dips below 20 fps very frequently. I have tried many things and cant figure out whats wrong.
