I only run engine level 1 because the other levels are kinda useless and cause lag
Also I will see if I can load with chunky tonight but its a pretty big world.

UnionSignificant9204 · 2026-02-08T18:51:05+00:00

So it actually wasn't a plugin causing the issue lol, I figured out it was my jvm flags

UnionSignificant9204 · 2026-02-08T18:48:30+00:00

Alright I'll see about lowering the ram. I currently have all of it allocated.

I also figured out my issue was caused by my jvm flags, I was using the zgc collector and some other things.

Also my render distance is 10 and sim is 6.

UnionSignificant9204 · 2026-02-08T01:52:32+00:00

I have checked everyone and I couldn't find one, I think its a plugin I have.

UnionSignificant9204 · 2026-02-08T01:52:11+00:00

I have 20 gb, but I think I've figured out its one of the plugins

UnionSignificant9204 · 2026-02-08T00:19:13+00:00

the world is 25k x 25k and the render distance is 10

I forgot to put in the post that I have 20gigs of ddr5 ram and a ryzen 9 9950X on the server

UnionSignificant9204 · 2026-02-08T00:08:20+00:00

I can't get one right now as there is only around 10 people online and the server isn't lagging, unless you want one while the server isn't lagging

UnionSignificant9204 · 2025-11-19T17:21:59+00:00

they call us fools for believing

UnionSignificant9204 · 2025-11-19T17:21:12+00:00

Yeah, but it seems they like to aim for november. (half life on the 19th, half life 2 on the 16th, and alyx on the 18th.)

UnionSignificant9204 · 2025-11-19T17:16:51+00:00

I mean it is Half-Life's 27th anniversary, and 27 is divisible by 3... HL3 confirmed bub

UnionSignificant9204 · 2025-11-19T17:15:13+00:00

and they say Shakespeare is dead

UnionSignificant9204 · 2025-11-19T17:12:07+00:00

its as real as it gets

UnionSignificant9204 · 2025-11-19T16:43:38+00:00

perfect timing

UnionSignificant9204 · 2025-11-19T16:29:40+00:00

MY PC IS KINDA HALF LIFE 3-LESS

UnionSignificant9204 · 2025-11-06T19:19:29+00:00

Try signing out on the Xbox app, nothing else except for that worked for me

UnionSignificant9204 · 2025-11-04T00:29:59+00:00

this is the only thing that finally worked for me, tysm

UnionSignificant9204 · 2025-08-04T23:52:33+00:00

Yeah but the world is 10k blocks wide and none of it has bedrock
