After having this issue:
Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher to this ticket.

If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

Well, ok.
That sounds strange, but try to reduce the allocated memory: Replace -Xmx8192M -Xms8192M by -Xmx4096 in the VM args.

i reduced it to 4096 and it's still happening. i have check for maybe entity problems but i haven't seen any issues. It happens in any part of the Nether as well... so it's not the specific chunk as i had thought.

Ok, was worth a try.
Let's observe that, maybe that's in fact MC-90605.

Mason Hocking 2016-02-03T21:23:53Z

based on the post, it's not the same as what i experience. i have just a really bad drop in frame-rate. i can go between dimensions with ease, it's just that frame-rate drop.

Maybe this has to do with render distance ? I have massive lag spikes too when entering the Nether but if I lower my render distance to <10 chunks before I enter the Nether there won't be any lag.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

Fixed in 1.9.3

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.

Very same issue....if you find a fix let me know [email protected]

I can confirm this is still happening in 1.12.2 and 18w19b. When entering the Nether game halts for about 5-10 seconds before returning to normal. I attached 2 logs but if you need different information please let me know how I can assist.

Increasing render distance (yes, increasing) seems to lessen the effect of the lag spike. My uneducated guess is that the client is doing some very taxing lighting calculations and by increasing the render distance it's doing those same calculations but spread out over a longer period of time instead of all at once bringing your fps to a halt.
