Lag spikes when sailing or flying long distances in a straight line, 1.13.1 #1833

Version: "OptiFine 1.13.1 HD U E3 pre2" Minecraft: Java Minecraft 1.13.1 Shaders: None, SEUS, Sildur's World: New world created in 1.13.1

I get pretty bad lag spikes when sailing in a boat or flying around in Creative Mode, sometimes bad enough where the game backpedals a little bit to catch up. For example, I'll hop into a boat and start sailing a long distance, and then the visuals will start to stutter as I'm sailing along in a straight line. Soon the video will 'rubber band' me back several blocks, similar to when the client is out-running the server. The same lag spikes happen if I turn around and sail back the direction I came, so it doesn't matter if the blocks spawning in are brand new or are part of an existing world. BUT... If I stay around the same small area; for instance, exploring a mine or clearing out an area for a home, Minecraft runs a solid 75fps (sync'd to refresh rate of monitor) with no jitters at all.

If I play the same world in plain 1.13.1 (without OptiFine), sailing around in a boat or flying around in Creative does not cause these lag spikes (although the framerate is only 50-75fps).

Can you post a debug screenshot (F3) and a debug crash report (F3 + C for 10 sec)?

Here's another log that might be helpful, there's a lot of 'can't keep up' and 'moved too quickly' warnings in it. I up'd the Mem to 4096MB instead of the default 1024, and I still get the jitters and rubber-banding when traveling long distances.
