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.\r\n\r\nIf 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).\r\n\r\nPC = Intel Core i7, Nvidia 1060, Windows 10, 12GB RAM, lots of harddrive space, bowl of Doritos"},"comment":{"url":"https://api.github.com/repos/sp614x/optifine/issues/comments/424925143","html_url":"https://github.com/sp614x/optifine/issues/1833#issuecomment-424925143","issue_url":"https://api.github.com/repos/sp614x/optifine/issues/1833","id":424925143,"node_id":"MDEyOklzc3VlQ29tbWVudDQyNDkyNTE0Mw==","user":{"login":"ManiacalMustard","id":43588423,"node_id":"MDQ6VXNlcjQzNTg4NDIz","avatar_url":"https://avatars3.githubusercontent.com/u/43588423?v=4","gravatar_id":"","url":"https://api.github.com/users/ManiacalMustard","html_url":"https://github.com/ManiacalMustard","followers_url":"https://api.github.com/users/ManiacalMustard/followers","following_url":"https://api.github.com/users/ManiacalMustard/following{/other_user}","gists_url":"https://api.github.com/users/ManiacalMustard/gists{/gist_id}","starred_url":"https://api.github.com/users/ManiacalMustard/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ManiacalMustard/subscriptions","organizations_url":"https://api.github.com/users/ManiacalMustard/orgs","repos_url":"https://api.github.com/users/ManiacalMustard/repos","events_url":"https://api.github.com/users/ManiacalMustard/events{/privacy}","received_events_url":"https://api.github.com/users/ManiacalMustard/received_events","type":"User","site_admin":false},"created_at":"2018-09-27T01:33:17Z","updated_at":"2018-09-27T01:33:17Z","author_association":"NONE","body":"Here's another log that might be helpful, there's a lot of 'can't keep up' and 'moved too quickly' warnings in it.
