For anyone running on older hardware, do not feel bad or pressured to upgrade because of this peculiar issue.

Despite highly specific shortcomings the FX series, especially FX-8350 is more then capable of running FF14 or most anything provided you are not attempting to push 120+ Hertz.

These older cpus are actually significantly more powerful then what you shall find in the PS4 and even PS4 Pro. I am confident enough in stating this that am willing to bet you could achieve stable frame rates on a Core2Quad. You should never experience severe stuttering even when frame rate is unstable, that is purpose of buffering audio. Extensive work goes into insuring this from myriad of developers working on emulators ranging from Dolphin to Dosbox to PCem...

Example; Partner achieves stable frame rate (60 fps) on one old Phenom II x2 with two unlocked cores. Yes this was thing, old non quad core Phenom processors can have cores unlocked turning dual core into quad core. Fun times! My partner does not suffer from audio stuttering.
