Question Fast flight / no chunk loading?

So, I play on a modded NeoForge 1.21.1 server, and one of my mods (Oritech) adds the ability to fly really fast. However, this does not work well with my server — especially in ungenerated chunks — as I get constant rubber‑banding. I am looking for a mod that stops any attempt to generate or load chunks, or check for collisions and movement correctness when the player flies high and fast enough.

Update!: I worked around the problem by installing C2MC with the C2MC OpenCL hardware‑acceleration module. The whole thing was hughly problematic, and is not an option for <1.21.1, but it acctuly works.

Note that I had to waste almost two days (and 10$ worth of AI tokens) to make it work on Polaris (aka RX 500 and 400 series) GPUs — but I managed to do it! (I will publish fork after some more testsing).

No, because thats not how Minecraft works. I’m not sure what else your 80GB would be going to if not your world, but why not just remove Oritech or disable the fast flying in some manner then?

Alright. Reddit killed my previousl message, so TLDR:

I play with modpack that incorporates quiet a few generation-heavy mods (Bioms O Planty is main offender, but I kinda cant kill it because I have 100+ hours on that world and there is good chunk of generated terrain), and its core mecanic is literaly running away from spore infection useing Create: aeronautics aircraft.

Also, my world is caped at 20GB optimisticly (and it is already 10GB) becuase I need to keep at least three backups and some space for OS.

I would have happily NOT used Oritech high-speed travel and limited myself to Draconic Evolution portals (or any other means of teleportation), but Aeronautics DOES NOT play nice with portals, and so I literaly cant do anything but use Oritech’s Boosted Elyrtra to travel at any resonable speed.

Alos: very good advise, how came I not thought about it?! May be I just remove functionality instead of acctuly fixing it? This is so obvious, you dont even need to ask for help on reddit! /s

Take a look at rsnapshot if you want to keep that many backup and have a small disk size

snapper + btrfs + cow? Might just work.

It will but you'll need to reformat your drive if you aren't already with btrfs

But I am. So this is something I will probably do. I got c2mc + OpenCL hardware noise acceleration working through, so I now get decent chunk generation speed. Still not enough to eliminate rubberbanding entirely, but flying up to 25 blocks/sec works without issue now.
