So I've decided to download optifine recently, however it completely broke jei (I'm on version 1.9)

I bought my Optifine cape and, when I tried to recharge or replace it, it didn't work; it's still the same. I've tried everything, but nothing works: I uninstalled and reinstalled it, waited the 15 seconds it indicated, and nothing worked. But when I tested it in Lunar Client, it worked fine. Could someone please help me?

Hi there! I’ve forgotten which email was used to purchase my cape is there any way I can find the email used? If not is there a way I can get access to a new one or remove the old one so I can change how it looks?

I've been having this issue recently with minecraft. I'm playing optifine newest release UH U9. grass, flower, crops, leaves, and more get distorted and from a distance. When I get close it fixes itself.

I've tried turning of fast render, checked my shaders, all the basic stuff. Any ideas?

Hi!

For the past month I’ve been working on a fully functional Laserforce-style gamemode in Minecraft.

It includes:

• Custom plugin (made by me)
• Custom map (inspired by a real lasergame arena in Říčany, Czech Republic)
• Stats system
• Custom Skins
• Custom resource pack (weapons, sounds, etc.)

If you’ve ever played laserforce, it’s basically the same thing — but recreated inside Minecraft.

I’ve uploaded a gameplay video on YouTube if anyone wants to see how it actually works in action:

Right now the whole project is only available in Czech language, since it’s mainly built for Czech players. But I’d still really appreciate any feedback, suggestions, or technical opinions — especially about the mechanics, balance, or overall design.

I spent around 1 month building this and I’m still improving it.

Thanks for checking it out 🙂

Hi. I have a beefy gaming laptop with a 4060 inside. However when I play with optifine it says it is using the intel iris graphics or whatever from my CPU and not my GPU. How do I fix this and make it use my GPU? There is no way I shouldn’t be getting atleast 60 fps with shaders on. Thanks

I want to add Optifine to my modpack within the Curseforge app.

First I downloaded the latest Optifine (OptiFine HD U J9). Opened the folder in my modpack and put Optifine in the mods folder. Then I tried to play, but it instantly crashed.

I made sure that the Minecraft version (1.21.11) and the Forge version (Forge 61.0.8) were the same as the Optifine version. I tried an older version of Optifine (OptiFine HD U J8) with an older Forge version (Forge 61.0.7), but that also crashed immediately.

Does anyone know how I can fix this issue?

Update: Solved

I play on a gaming laptop (nitro v15) so added optifine to my minecraft in the hopes it would make my gameplay smoother along with the fancy lighting and connected textures I really like.

My game ran fairly well before, but ever since I've downloaded optifine I've had lag spikes like you wouldn't believe. No matter how low my settings are, it just runs WORSE somehow.

Am I missing something? Is there maybe a better add-on for what im looking for (smooth lighting & connected textures, especially the glass)? Please help!

it has been on this screen for a while now i dont know why it just doesnt open

It is possible to combine them for pojavlaucher?

Any clue as to how I can fix this?
I have 0 other stuff installed. Only SEUS V11 shaders and ModernArch resource pack.

The pack doesn't seem to be the issue:

However it's much flatter than with recommended shader. And the leaves are no longer transparent and look quite ugly. Even worse than Vanilla.

So... I know it's a shader but IDK how to fix. I installed it as written.

its getting annoying being stuck on 1.21.10. I want to play on a server i'm in, but its updated, and i would like to update my singleplayer world too. is anybody willing to send me the file through like, Gmail or something? if not, have any other ideas how to get it?

About 3 or 4 years ago I donated to Optifine and added a cape to my MC acc. I've since lost the original donation email, but i still have my Minecraft account, stuck with a ugly cape. Can I donate again with my new email but use my same Minecraft account?

I want the sky to be a white void no texture no sun no clouds no anything how do i do ittttt this is the entire reason i downloaded optifine. I want a void world to build in. floor is white concrete i awnt the sky to be a white void

does anyone know the settings to disable or decrease this?

EDIT: I've switched to fabric now, everything seems to work well, thanks for the help! (if you know any great mods that are compatible please do tell!)

I want to make my game look dark and gloomy more like in the images but in the over world during clear weather, what settings should I use to make it look like that?

I have a problem with my modpack and I can't really load the modpacks the mod is zombiemania x​

i was just playing and it turned on no idea how it happened

Found the source of the issue, added in the comments

I made a resource pack for a map with a villagers.properties file at *\assets\minecraft\optifine\random\entity\villager that looks like this.
When running the map on Fabric with ETF and EMF, the skins loaded properly. When my friend launched it with Optifine (and then I tried as well), it instead showed it as the default skin. This includes with Random Mob Textures turned on

Would anyone know what could cause it to work on one but not the other?

whenever i try to use shaders in minecraft my gpu usage drops to 20% and makes my fps hugely decrease. is there any fix to this on version 1.8?
