This is unbelievably helpful, I don't have to tests nearly as much now thank you thank you thank you 🙏🐦 Absolute GEM!!! 💎

There is mod for finding sources of lag: Observable. It can measure your server performance and find the blocks and entities that use the most processing time. For me it was mostly chutes, funnels and carriage contraptions.

You can use an attribute filter with the attribute "Is badly damaged" to remove the swords as they are almost broken to repair them

Having done some lag busting myself, its always fun doing tests and coming to realisation that youve chosen the laggiest way to do things :D

Had this video recommended to me and was curious about lag, bro tricked me into watching his modded survival let's play and enjoying it 😤

Blaze burners just produce massive amounts of particles and the fact that the blazes look at you also causes incredible lag

Uh Foxy, the Mending sword is already doing it's thing on the deployer. You don't need a contraption to repair it when it's already repairing itself.

This gives me an idea of a world where towns are connected by trains to transport items, and there's only maybe 1 major factory (or relatively smaller ones) per village. I guess at that point you'd need to force load chunks though if you want them all to run...

I think it could have been worth measuring lag when not looking at things too. Some things can be lag-free if they’re hidden, but others are poorly optimized and lag you through walls. This could be a game changer for a few blocks

I was experiencing alot of lag on my create world and I found out that running /flywheel backend batching improves a lot the FPS. Don't know if that's your issue but I tought it help.

V good episode! Even though it wasnt in-game progress or roleplay I actually found the lag investigation interesting and genuinely useful as a create server host

This series is amazing Foxy. Watched all these before i started create. Now rewatching to learn more🎉

While I do appreciate the test, and it is *mostly* accurate, it only tested the lag blocks produce on their own. The way storage drawers work means that trim itself doesn't lag, as your test proved, but trim *does* increase the lag generated by drawer controllers, and/or drawer controller... "interns" (since the algorithm doesn't like the other word). When an item enters a drawer controller or "intern" it needs to find a place to put it, so unless it has a list of precached locations it checks the 6 adjacent blocks to see if they're either a drawer that can fit the item, a drawer that can't fit the item, or a piece of trim. In the first case it places the item and the process is finished, but in the second or third it has to then check the 6 blocks adjacent to the drawer or trim it found, (minus the starting block), so each step out means 5 more checks. Thus, for an item to enter a drawer controller and reach a drawer 20 blocks away, the game has to check a minimum of 101 blocks (and that's assuming a straight line with no other drawers attached). When it's a sprawling storage system, you'd potentially be looking at tens of thousands. There are ways to cut down on the number of checks (i.e. via caching drawer locations), which I imagine the mod does, but even that still generates lag; the mod has to either recheck pathways whenever you place or break a block (unlikely, given how that would put unnecessary strain on mining and quarries), or periodically recheck cached pathways to make sure they're still valid, which means the system wouldn't lag quite as much when dumping in items, but would still passively lag even without inputs (and given how much the drawer controllers lagged in your test, that'd be the most likely scenario). TL;DR: drawer trim doesn't lag *on its own,* but it still contributes to lag a lot more than your test would indicate when it's connected to drawers and storage controllers. The test was helpful and I appreciate it, and drawers are definitely still better than belts, but it is a bit misleading (albeit unintentionally). That aside, I love the series, and I hope your holidays went well.

I would suggest taking a look at TangoTek's latest Create series and skimming through to see the cobblestone generator he used. It uses much less space (roughly 10x10) and is just as fast as your setup. While his only creates 56 cobble every half second, adding one more row is easy to bring it up to a full 64. I use it in my create world.

create + mythbusting = yes plz ❤ amazing vid, thanx Foxy! i hope you had an amazing holiday season 😊

Whenever contraptions stop, like trains, you can feel that in your frames. A second primary cause of lag are funnels, mostly on large inventories, like humongous drawer networks in a certain ski resort...

Thank you so much for doing this experimentation and letting us learn lessons from your work. As someone just starting out with the Create mod, I know I'll take this to heart. I don't know if I'll ever build to the scale you are, but still. Compacting things is nice. I'm actually quite curious HOW you compacted everything. Cutting out all the building bits or speeding them up kinda makes it hard to follow.

another tip!! if you use the Functional Drawers mod (i know you already have storage drawers but just hear me out) you can use the fluid drawers in that mod for most likely a much less laggy fluid storage solution! it works with create pipes and looks pretty good too. it might solve that problem of tanks creating lag!!

Ive done it! Its taken 4 days but i binge watched your entire create series up to the current video! I found you the other day and enjoyed your humor so much that i wanted to watch from the beginning.

Thx for your incredible investigation and i wish you a good start in the new year 🎉🎆🎇

Foxy, you seem to have not learned that create allows you to enchant tools automatically without need of books. You can build enchantment factories. There is even an enchanting list that you can give a blaze burner to enchant things.

Foxy you're the making efficient and effective farms and mechanism great work keep it up

"I just wanna sell you stasis!" Ah, I see that Bungie has become a Minecraft Villager.

Not too surprised to hear that belts cause a lot of lag. Hoppers are one of the laggier vanilla items because they constantly check 'is there an item on top of me I should add to my inventory?'. So I'd expect any Create inventories where you can just throw items in, like Depots, Chutes, and Conveyors, to all have the same problem.

This is what I needed to improve my iron farm, thanks!

some amazing lessons and data to unpack there, very interesting

I was actually amazed at the amount of create contraptions, trains (to include npc 'ai'), and framed blocks you were using and not having massive lag issues. Maybe the over 1k fps base helped, but it definitely shoed the benefits of running even a single player world in a server.

another thing i have noticed because you're using the sound physics mod, it introduces INCREDIBLE lag when paired with the create mod

Tanks have transparency which can depending on the engine be costly at large scale. The belts are probably because of how minecraft handles entities which are invisible and get replaced with the entity model in which is "on" it since the object your see on the belt likely isn't real and instead just a representation of the item in it similar to how a chain of hoppers works.

This episode is like a life lesson

You're in the rare case of just simply too many entities being loaded in one area. Time to expand and get that world wide train system in gear.

I have been waiting for this eppisode.

You make amazing videos. And very usefull for me, thank you so much 🤗

I will have watched this video at least 20 times by June lmao ty for making it

You should incase some components like pipes and chutes with casings so the game can render a normal block instead of it's complicated model

I feel like if you wanted to further slow down the use of durability on the blaze farm swords adding sharpness to them could help somewhat? I figure the fewer hits it takes to kill them the less durability it'll use in the long run.

I love going Nomad early game and Easy Villagers has made that a sweet reality. The airship transport from Immersive Aircraft doesn't hurt either. 😄

Amazing episode!

7:25 For this "problem" i got myself a mod that adds a few more enchantments. One of them is "Indestructibility" what makes the item it gets put on unable to loose durability. Its a "bit" OP but hey, for a Mob farm its a good thing. (And for your ABSOLUTE ULTIMATE Armor you spend AGES to make it and enchant it and you dont have the motivation to make it again or fix it when its broken. XD) The mod is named "More Enchantments" by ninjabunny_1. (It has a few REALLY nice enchantments that are actually pretty useful so Indestructibility is not the only reason for this mod!)

yoou should try adding JER (just enough resources) and JEP (just enough professions), they are like JEI, but give information on mob drops, dungeon chests, and even vilager trades!

Hey Foxy. Not sure if it's too modded for you, but if you add apotheosis you can make the spawners chuck out more mobs and quicker (can also silk touch spawners). You could also add mob grinding utils to add something to kill them where you can add high levels of looting for more drops.

So for the pickaxe repair, You have rotation and cogs, generally you want them to go as fast as possible. But what if instead you tried to get a wheel (or arm) to go around once per cycle, You know so when the hand got back to 60/0 the detector block would redstone, and that would be how often you want the pick repaired. Or any contraption really, could be a minecart, just only let the pick come out for repairs based on about how long a half a durability bar lasts. or you could use the redstone timers

if you have the creates crafts and additions mods, you can use biodiesel to superheat blaze burners for much more power in a steam engine! although you have blaze cakes being automated so that might not be necessary, it still might be a way to use the diesel factory for another purpose

Just found this video here. Great work! One thing ive done is use a separate java for minecraft called adoptium. Literally gained 100fps and was able to go from 8 chunk remder distance with lag spikes to 40 chunk render distance.

happy new years eve Foxy

Lag is pollution. Thanks for doing your part and cleaning it up. 👍

As someone who has had to watch far too many let's plays to try and gain information, I was happily surprised to enjoy your presentation style and video. My only wish is you would have tried some things like andesite encased shafts, and I didn't notice encased chain drives in the list of tested. Could have been me though.

Thank you bud, Was consideing create but think for me will use it for more asthetics like the odd water wheel and winmill for movement etc

Foxy there exists a mod called easy villagers which allows you to pick up villagers as items, and place them inside of blocks that make breeding/farming/curing villagers and trading wayyyy easier. I wonder if that’ll also help lag

Before everything, I know a little about create coding and belts should be those that are the most laggy because they have to: Check for power input, check for items coming through and take them from the last belt block, check for power coming throguh the belt, power things through itself and take dropped items or things from other belts

FYI fps drop from drawers is largely coming from the display. So if you have several drawers in one area and don't need to see the contend all the time conceal the label to take away the frame impact of the drawers nearly completely.

Man I’m glad u made things smoother but everything looks so empty and dead now.

12:19 wht was that such a good villager impression?!?

Great video! Very informative and fun, sad about the monkeys not really needing to do anything though

Happy New Year's Foxy.

since belts are causing lag in smaller areas, a long vault with funnel is faster than belts.

When i was playing the create astral modpack, i hadnt realized at first that belts were the cause of my lag, i barleu get 60 in vanilla mc but belts in create are the biggest lag generator

great discovery

In general, everything holding fluids as inventories cause a lot of lag, because they have to render the amount of fluid inside.

Man, cant wait to see you sink your teeth into the crude oil stuff. Create the factory must grow is one of the coolest create addons

first world problems "My minecraft FPS isn't 900+ oh noooo" lol most ppl would be happy with 40 FPS, but this is helpful to know never the less

In my experience the framed blocks create tons of fps lag but it's not consistent, some angles are way worse

the belts being a source of lag makes sense, they are inventory blocks, after all, and inventory blocks are notoriously useful for chunk-banning.

You can actually use the same Create addon that adds the Disenchanters to duplicate enchanted books, if you want an endless supply of Mending, Unbreaking, and Looting swords.

Happy new year!

I like to create shut down mechanisms that turn off production when everything is in stock.

If I'm not completely wrong, basically all block entities that interact with inventories like belts or chutes are a cause of lag on mass scale. Especially the ones that extract or push items from anything, since they are constantly checking if they can pull smt. It gets a lot worse if it's interacting with a filter. Rollers and harvesters are worse too since they're checking if they can replace/break blocks. The easiest way to reduce lag a little is to build more spread apart so it's not too clustered together, The server tps will still tank a bit though. Its a great and informative video ^^

Quack sound effect on 1:24

The things that causes lag in create are the filtered smart chutes and brass funnels/tunnels. This becomes a huge problem when connected to inventory systems.

As you have enchantment industry, look at the enchantment blaze burner. you can also duplicate enchantment books using the printing thing (Looks like the sprout that fills buckets)

Love your channel

Happy New year

i've never touched belts or tanks in my Create Mod worlds, i just build trains. i think its the track curves and the bogeys that create the most lag, the Create Mod animated doors probably do a little too, but doesnt often make sense which is the worst, eg running trains are sometimes less laggy than disassembled trains

I just came to see what made lag, but then I got invested in the Lets Play. dangit!

Moral of the story: Use the god damn trains. Build every factory in a different location and connect them with a vast train network because a few trains is probably not as laggy as a whole town of entities.

if you have problems with transporting items, you can use the mod enderchest. You can create several different chests with a color code.

110 mods is small, and a good number of those are probably tiny mods that have little impact on performance. i get that testing on the empty world was meant to prove it was the stuff in the world, but most mainstream packs are running the 200 mark or more (ignoring outliers like all the mods or packs built for performance with few mods which obviously do not count).

You have the enchantment industry create addon, you just need 1 book of any level to duplicate and level to max level, and automate enchantment with only 1 copy of each enchantment.

This is not really on the lag topic, and I am not sure if you already know this fact as I have not seen 100% of your videos (Yet!) But as well as using the Diesel Generators update for the Biodiesel, you can also use it on blaze burners, Using the Create: Crafts and additions mod; it is possible to make blaze burners take liquid inputs. Using a Rolling Mill on a piece of bamboo will create a straw, and right-clicking a blaze burner with said straw will let it accept biodiesel as a fuel. On top of that, the blaze burner will not only be fueled but it will be superheated as well. While testing run time in a creative world, I found a bug where the blaze burner would stay superheated well after it was out of fuel. (I am not sure what was causing this, or if it is still present in all worlds) Even still, the run time for a single bucket of biodiesel is at least nine minutes. However, as it only takes nine buckets (or less if using pipes) to superheat nine blaze burners which will power a maxed-out steam engine generating about 300,000su for nine minutes, it is a decent alternative to the base diesel generator (although it is a decent bit bigger)

How much ram do you allocate for minecraft foxy? I have not been able to find a good middle ground. I either do to much ram which affects fps or not enough ram. I am playing with over 600 mods however even when I'm in an empty area with no create stuff, my fps is only around 60 even though I have 64gb of ram, a ryzen 7 5800z and a 3080ti so I'm looking for any suggestions to help improve my fps idk why it's so bad even in areas with nothing in it when I have pretty good hardware. Keep up the great work!

Developers must have seen your video and corrected it. You can also make gunpowder using harming potion. Also if you want to keep the cobblestone supply up you could us Tangos glitched farm.

I remember something about the framed blocks being a huge source of lag on the gregtech modpacks. we are talking gregtech that already laggy so if framed blocks was a huge source maybe some of the lag can be bc of the buildings. it's a shame if it is , bc those buildings are fantastic

Chutes are laggier than hoppers because they: 1: Have to actually have the items inside of them so that they can be rendered when needed. 2: They are much faster than hoppers. 3:They have to check for fans AND their direction.

Fun Fact: Standard _Netherite Diving Boots_ prevent Players (You) from being affected by Conveyor Belts. An investment into that piece of armor would be very useful moving forward

It seems like almost all the blocks that cause FPS lag are the ones that display, move, or store items or fluids, including the filters on things like the saws. I think whatever render code is displaying those item textures/models is running even if there's no item in those slots, which is causing all the lag.

I was shocked that the mechanical rollers were lagging your server, the most

Happy new year

Another create mod might be able to help as well, at least with cobble gens. Create mechanical extruder. A

the belts are technically chests so it kinda make sense for them to lag so much

You can also use a mod called create better config and it lets you configure everything in create

this is a whole research study

Dude i searched up your modpack before you even said it in the video I thought it was someone elses and it was not your modpack but now i know

there is a mod that allows you to use gasoline and diesel on blaze burners it produces max heat with a blue flame the mod is create: crafts & additions. this mod also has electricity

Your villager trade change to the option you can "afford", and when you buy a unbreaking book, which cost 36 emeralds, it only leave 28 emeralds which isn't enough to buy another unbreaking book, so Minecraft switch to the option you can buy, and so it switch to stasis

One thing you can do is use crafts and additions to use electricity to power motors or get create: new age that does the same but on a new level.

Maybe use the pipze mod if you already doing that with drawer connectors, as they if i remember correctly are pretty performance friendly and it would look some more interesting.

I cannot express my thanks for this research. I made one factory to do Confectionary, and it's KILLING my FPS 😂

Wow I didn't realise just how laggy create was. How would you feel about a short tutorial on how you've utilised the storage drawers, as I thought the controllers had a block limit to them, but using the trims, you've made massive lines of them to make 1 big system? It would help us beginners 😅

just make sure you make multeble town. that helps against the lag, it isnt the prettiest but it will do the trick

Entity culling mod? It could rly help to reduce lag when u actually dont see entities behind walls so it will load them individually
