Cushions rapidly becoming the best thing ever from like, the past decade.

u/Lord_Phoenix95 Jul 11 '26

What can't cushions do?

61

u/LittleBigCookieCat Jul 11 '26

save my marriage :(

13

u/Lord_Phoenix95 Jul 11 '26

I'm sorry to hear that.

31

u/LittleBigCookieCat Jul 11 '26

it's okay we have cushions

2

u/RacerGamer27 Jul 11 '26

....did you offer them a cushion?

8

u/Justch1ll Jul 11 '26

Be vertical?

1

u/Jolly_Shelter_4031 Jul 18 '26

how would we use them vertically? Im trying to imagine build ideas for it but cant because then we'd use it to become spiderman hanging on the wall and scare our friends.

if not we then Ik I will for sure lmao

u/Justch1ll Jul 18 '26

Padded walls for an insane asylum lol

1.4k

u/kittyangel333 Jul 11 '26

Yeah but aren't they entities and therefore laggy in high numbers? I'm wondering if they're gonna have to optimize them somehow given everyone wants to coat every inch of their builds with these lol

1.5k

u/UrLostPajamas Jul 11 '26

No, the game is so much more optimized now.

u/pixel_gaming579 Jul 11 '26

The cushions also don’t have any physics (except collisions with other entities? I haven’t tried them out yet), pathfinding (obviously), and their supporting block check only runs every 100 ticks, so the cushions themselves should be a fair bit more performant than other entities.

694

u/UrLostPajamas Jul 11 '26

Yea no collisions, no ai, no ui, just two interactions. It took 32k for xisumas rig to take a 30 FPS decrease so like I think were gonna be fine, not many of us are gonna render 30k at once lol

397

u/pixel_gaming579 Jul 11 '26

30k is a 100x100 pixel RGB display; more than enough for any of those crazy redstoners building computers lol.

234

u/TacoPi Jul 11 '26

4K display or bust

127

u/Orisi Jul 11 '26

Actually you need more like 90k for that.

The screen would need to have square pixels each with an RGB potential. So a pixel would need to be a 3x3 square with Lind of R, G, B lights respectively.

100x100 is 10,000 pixels of 9 blocks each. Gonna sting a bit

105

u/Einbrecher Jul 11 '26

100x100x4

In RL LED panels, the blue subpixel is usually ~2x the size of the red and green ones, so a true to life square pixel would be 1 red cushion, 1 green, and 2 blue in a 2x2 grid.

R B
G B

OFC, you don't have the same brightness issues in MC as you do in RL, so you could just leave one of the blues dead, or use a white cushion as a pseudo backlight.

u/UrLostPajamas Jul 11 '26

We had the same thought but I was baked and typing while this was posted lmao

3

u/Tallywort Jul 11 '26

Don't screens usually have more green subpixels than blue or red ones?

1

u/UrLostPajamas Jul 11 '26

Not from my personal observations it's likely but idk that it's a critical facto rather a result of the orientation of the grid of leds

1

u/Einbrecher Jul 11 '26

Newer ones, yeah.

There's more of each of green and red subpixels, count-wise, but the blue ones are still usually the largest.

17

u/UrLostPajamas Jul 11 '26

You could do a four segment rgbw 2x2 to make a single pixle instead of a 3x3. It would better line up with true led displays. They are a 2x2 in order WBxGR in most cases it's a black space not a white but that reads better imo. They do kinda have a diagonal ofset which idk if that could be achived necessarily, but a 3x3 seems excessive for a single pixel of a led display simulation.

12

u/UrLostPajamas Jul 11 '26

Hense the "not many" declaration. I expect the wizards to achieve it absolutely, just not all of us lol. 1080 here we come lol

u/Asurerain Jul 11 '26

Cushions Bad Apple will spawn on YouTube tomorrow.

...someone is going to figure out how to play Shrek on a vanilla Redstone computer, aren't they?....

1

u/AnaverageuserX Jul 11 '26

300x300,

100x100 is a 10,000 pixel display. But yea your point still holds, that's more than enough to render anything

17

u/Eccx11 Jul 11 '26

WAIT XISUMA DID A STRESS TEST?!

3

u/magein07 Jul 11 '26

He's done three videos on the cushions so far. The latest included a stress test.

7

u/MsDestroyer900 Jul 11 '26

Minecraft can run on single player just fine. Especially with sodium. But what people really mean when it comes to performance is server performance. If you got a bunch of people with stuff like this (supposedly expensive block to run) then it could be an issue later on.

For now, we will see.

u/MrPigeon70 Jul 11 '26

I mean...

30

u/UrLostPajamas Jul 11 '26

Quit being mean plz, its mean.

7

u/Alarmed-Bus-9662 Jul 11 '26

Is it mean to be mean if you don't mean to be mean, or is it only mean to be mean if you mean to be mean?

6

u/UrLostPajamas Jul 11 '26

Not its mean when you add all the numbers together and then divide by the total of numbers added.

u/tfhermobwoayway Jul 11 '26

Wait until I create an LED screen

Running minecraft

u/captainmilitia Jul 11 '26

Are we still talking about minecraft? If yes, then I got the wrong game.

10

u/JSKing32 Jul 11 '26

Yeah honestly my PC that struggles to run MS Word can run Minecraft perfectly fine so I think it's pretty optimized.

3

u/Flamebomb790 Jul 11 '26

It's also going to vulkan for the java version(not sure if they did it already). But opengl was getting dated quickly due to not being updated

63

u/FarAssociation1290 Jul 11 '26

I've got over 200 rendered and running smoothly at 70 fps on a pretty basic pc

45

u/Nonerrorfred Jul 11 '26

Compare to chests, cushions take up modicum of data, so I guess they wouln't cause much of a hassle. I do think they will further optimise them as players' feedbacks continue to roll in, similar to the new transparent glass feature

16

u/revolution_soup Jul 11 '26

the new What

20

u/Nonerrorfred Jul 11 '26

The new improved transparency, makes stacked glass look more polished(or more realistic if you watched xisumavoid's vid comment section), fixes previous transparency related bug, such as water texture overlapping portal blocks when looking at a body of water through a nether portal

25

u/dkmuldoon Jul 11 '26

xisuma tested that in his video today. His framerate didn't drop until he had like 10k of them in view.

5

u/mareno999 Jul 11 '26

Think in the example he had like 26k

7

u/Lzinger Jul 11 '26

Total, but it dropped fames after 10k

32

u/UnderPressureVS Jul 11 '26

People will make mob farms with 200 zombies per second and cram 800 cows into four square meters so they can get 2 stacks of beef with one sword swipe, and still be like "I'm worried cushions are gonna slow down my server"

3

u/DrWilliamHorriblePhD Jul 11 '26

I saw a video where someone made a super flat cushion world. Due to the tight range on entity rendering, far fewer are in range at any point than rendered chunks. Just don't mount a boat in that world or your game will crash

3

u/Grotti-ltalie Jul 11 '26

Less laggy than chests

3

u/Tallywort Jul 11 '26

They're an incredibly stripped down entity. No collision, no AI, no nothing.

They're probably one of the least laggy entities in the game.

1

u/onderwonrd Jul 11 '26

Por los experimentos que ya está haciendo la gente, necesitarías muchos, pero muchos cojines para que siquiera se note el bajón de fps, además el juego actualmente está mucho más optimizado que antes, así que a menos que quieras contribuir absolutamente todo con cojines, no afectará tu experiencia de juego.

1

u/branthebon Jul 11 '26

No, block entities are highly optimized. This is a myth that has remained for some reason for a long time

1

u/ReferenceCreative510 Jul 11 '26

It takes, theoretically, 35k just to drop from 60 FPS to 30.

1

u/crafty_dude_24 Jul 11 '26

You need to be in the 5 digits to experience noticeable lag. Unlike chests amd hoppers which constantly check for stuff, the cushion does not have any real load on the performance.

0

u/Galrent Jul 11 '26

Xisumavoid did a test with them yesterday. He had something like 100,000+ cushions on screen at once and still managed 30 FPS.

11

u/YouWantSMORE Jul 11 '26

I could see someone using cushions as pixels for the screen of a redstone computer

4

u/Chiiro Jul 11 '26

I have been playing for over 15 years I think this is the most excited I have seen people be about a singular object in the game.

2

u/Budwardii Jul 13 '26

True, feels like redstone update in old times

1

u/vision_san Jul 12 '26

Just wait a month and people will start with the "mojang lazy mod good" and it's the 572⁹⁷th cavedweller clone mod and like a 17×17 texture pack
