I'm running on 1.12.1, and still having this issue. I can play in the overworld just fine, but when I initially enter the nether, my fps drops from around 120 to 2 for about 5 seconds, then returns to a normal level and I can continue playing in the nether without issue. I have an AMD fx-8150 8 core processor and the GeForce GTX 1050 Ti graphics card, running on Windows 10.
