OptiFine has to be the most popular Minecraft optimization mod that allows users to enhance the game graphics by enabling HD textures and additional game key mappings.
Minecraft with HD textures have stunning graphics and offer an entirely new gaming experience. However, there can be issues caused by OptiFine, regarding the mapped keys or even some additional features that come with your OptiFine installation.
Of all the errors that can be caused because of your OptiFine mod, the OpenGL errors can be very troublesome. This article contains all the details you need to know and understand before trying to fix the Minecraft OptiFine OpenGL error 1281.
What Is OpenGL?
When OptiFine is installed onto your Minecraft fame, it allows users to add custom texture packs. Because this mediating mod uses a huge load of system resources, the game output (measured in FPS) can become low.
To avoid the drop in Frames per second, OptiFine introduced an element known as OpenGL. This is added into the game as a configuration and is used to make the game render the surroundings faster than normal when HD textures are being loaded.
When OpenGL is enabled, it drops the weight of rendering the game world from the shoulders of the computer’s processor, the graphics card, and the necessary drivers.
What Causes the Minecraft OptiFine OpenGL Error: 1281 (Invalid Value)?
The Minecraft OpenGL 1281 error (invalid value) can be caused by quite a number of reasons. We have listed them below.
- The OptiFine client is outdated or has expired.
- Incompatibility of the Windows version.
- Out-of-date graphics drivers
- Incompatible or corrupt mods
- Errors in the Java client
Most of these reasons are related closely to the game graphics. This doesn’t mean that more powerful graphics cards can help fix this issue. If any of the above criteria is present on the computer, you will see the following error message in the in-game chat –
OpenGL Error: 1281 (invalid value).
Fixing The OpenGL Error 1281
To run high-definition Minecraft graphic textures without a graphics card of a minimum of 6 GB graphic memory is a bad idea. This is because mid-range graphics cards and their drivers do not have sufficient heatsinks for cooling the system down when rendering HD textures.
You can burn your mid-range GPU out or you may not get optimal output. No amount of cooling or memory upgrades can save your graphics card from failing or dying out.
It is only safe to launch HD textures if your GPU supports ray-tracing. These include the NVIDIA RTX series and the AMD Radeon RX series.
However, upgrading your Graphics Processing Unit (GPU) hardware is an expensive option and is not to be considered until all the below solutions are implemented.
- Turn The Shaders Off
- Disable The Active Mods
- Disable The Show GL Errors Option
- Update To The Latest Version Of OptiFine
- Check If Your Mods Are Compatible
- Download The opengl32.dll
- Install The Java Packages Manually
- Update The Graphics Card Driver Software
- Install The Latest version of Java
- Adjust The In-Game Video Settings
- Remove & Reinstall Minecraft
Solutions To The OpenGL Error 1281 On Minecraft
Turn The Shaders Off
The HD textures are popularly known as shaders, by the Minecraft community. Even when the Minecraft game is installed on your computer for the first time.
The game settings interface has an option that allows users to enable or disable extra shaders that are to be installed by the players through the OptiFine client.
Sometimes the shaders are the factors that are responsible for the OpenGL 1281 error. If you do not know how to disable the shaders, use these steps.
- Launch Minecraft on your system in OptiFine mode. This can be done through the Minecraft Launcher, which comes with the game installation.
- Open a Single Player or Multiplayer world and pause the game by pressing the Esc key, once the world is loaded.
- Choose the Options… button and you’ll see access to the different aspects of the game settings categorized. You can also go into the Options in the game main menu. We recommend launching a world and going into the shaders option for you to see immediate results in the texture packs.
- Go into the Video Settings… and select the Shaders option. This option will not be available for users without OptiFine installed on their computers.
- On the Shaders page, you should be able to see all the Minecraft shaders installed on your computer. At the top of the list, you’ll see the OFF option. Click on it.
- Wait for the default 24-bit or 16-bit shaders of the game to load. You will see a Mojang loading screen during this process.
Once your graphics return to normal, try playing the game to see if the OpenGL error still exists. Even if it does, you’ll notice an obvious boost in the game frames.
Disable The Active Mods
Since Minecraft is powered almost entirely by Java, the programming language, thereby allowing users to include tons of different modifications into the game script.
The Java Edition exists because one of the Minecraft developers, Marcus ‘Notch’ Persson, found it easy to code the game in Java as it also does not create complications for gamers who play on Linux or Mac.
These mods that can be included in the game can become corrupt due to virus attacks or hardware failures. However, it is almost impossible to know if the mods are corrupt.
It is safe to assume this and remove them from Minecraft to see if it gets rid of the OpenGL error 1281. Once they are disabled completely, add the mods back one at a time to check if the OpenGL error appears again.
If it shows up after the inclusion of a specific mod, this mod is the culprit. You cannot use it again. Find a safe replacement for it and include it in the game. If you cannot, there will be similar mods.
Disable The Show GL Errors Option
This is not a solution but a method to hide the OpenGL Error 1281 Minecraft error message and prevent it from being displayed in the game chat. This option has to be disabled only when you cannot fix this issue and it persists.
Here’s how to stop the GL errors from being displayed on your computer.
- Launch Minecraft with OptiFine. Make sure both the game and OptiFine are up-to-date.
- When the game finishes loading, click on the Options… button in the main menu.
- Select the Video Settings… option.
- From this page, proceed into the Other… option.
- At the bottom-right corner of the options and toggles, click on the Show GL errors toggle button to disable this feature. It should be enabled by default.
- Restart the game for these changes to take effect.
The option should now read: Show GL errors: OFF.
Even when this option is turned off, you will experience a visible drop in the frames as the game renders new chunks.
Update To The Latest Version Of OptiFine
AN out-of-date version of OptiFine is another reason that can cause OpenGL errors on your Minecraft client. This might not immediately cause issues with your system but over a long time, when a newer version of Minecraft is released by Mojang.
Under circumstances that an OptiFine update is available for the installed Minecraft updates, you will receive an in-game notification/hyperlink in the chat. This can be used to download the OptiFine update.
- Launch Minecraft and open a world. It can be a single-player or a multiplayer world.
- Once the world is loaded up, you will see a message in the chat stating that there is an update available for the OptiFine installed on your computer.
- Press the ‘T’ button on your keyboard to bring the in-game chat up. This is the default key but could also be a different one, depending on your key binding.
- When the chat is up, you will be able to use the mouse pointer. Click on the yellow link and on the confirmation page, proceed by going into the link.
- A tab on your default browser will open the OptiFine site with the available download. Click on the Download button and wait for the download to complete. OptiFine setups usually come in the .jar formats. Though these files can be opened by WinRAR, it is a bit complicated. We recommend using the Java for Minecraft tool.
- Right-click on the downloaded .jar file and choose Open with > Java (TM) Platform SE Binary.
- In the installation window, click on the Install button. The process shouldn’t take more than a few seconds.
- Restart the game and check if the update message is still available. You will have to keep restarting it until you don’t see it.
You needn’t worry about re-including the shaders and texture packs again, after an installation of an OptiFIne update.
Check If Your Mods Are Compatible
Another factor that has to be taken into consideration is the compatibility of the mods with the system specifications and the version of the game. For instance, a mod that is designed for Minecraft version 1.15 cannot be used with the most recent 1.17 (as of October 2021).
This is because of new inclusions of game elements that can be interfered with by the mods.
To check if the mods are compatible with the version you have, you will first have to make note of what version your game is on.
You can simply open the Minecraft Launcher and take a look at the active version, which is displayed in a drop-down menu at the lower-left part of the screen.
After you make note of it, go to the website where you downloaded the mods from. Go to the page of the mod that you have on your system. This page should have information on which versions of the game can host this mod.
Only if these conditions are met by the Minecraft game and the mod, will you be able to play with the mod without any issues. You can some mods made for an outdated version with a newer Minecraft version but there are no guarantees that it’ll run as expected.
Download The opengl32.dll
We spoke to a Minecraft code expert who immediately suggested downloading the opengl32.dll and including it into the Minecraft app data.
A lot of other Minecrafters reported that this was an excellent solution to any OpenGL errors on your computer.
This solution does not just involve having to download this DLL file. There are a few more steps you have to take, in this resolve.
- Open a web browser and download the open32.dll. You will have to download the 32-bit or 64-bit depending on the OS version of your computer. There are a number of websites that have this and other DLL files available for free download.
- Right-click the Minecraft Launcher and select the Open File Location option.
- In this directory, go into the runtime folder.
- Now, proceed into the JRE-x64 folder and open the bin directory.
- This is the location where you have to copy-paste the downloaded opengl32.dll.
- After this, restart your PC and launch Minecraft to see if the OpenGL error exists.
Install The Java Packages Manually
There is another way to extract Java on your computer. If the first method did not work for you, you will still be able to face the OpenGL 1281 error. You can also manually do it.
This is not a safe method to install Java since a number of problems have been noted to have appeared. Only follow the below-stated steps when the previous solution did not kill the OpenGL 1281 error.
- Search for System Information and open the first search result.
- Look at the System type section in the System Information window. You will either see x86 or x64. x86 means that your OS is 32-bit and x64 is the denotation that your computer has a 64-bit OS.
- To get the Java files, launch a web browser and go to the Java page on the Oracle website. After you’ve downloaded it, unzip the files to a convenient location.
- Next, copy the path to the location where you extracted the java file and paste it into “C:\Program Files\Java” (32 bit) and “C:\Program Files (x86)\Java” (x86) respectively (for 64 bit).
- Now open the Minecraft mod manager and go to the bottom of the window to Edit profile.
- Then, uncheck the executable file checkbox and replace the path with the proper one.
- Finally, reboot your computer to keep the changes that were made recently.
Update The Graphics Card Driver Software
The Graphics card and its drivers play a very important role in the running of any game on the computer. In the case of an OpenGL 1281 error, it is very important to keep these updated.
This action not only fixes visual bugs, glitches, or issues but also increases the performance of the computer while running games.
The easiest and safest way to update the graphics drivers is to use a firmware management interface. For NVIDIA graphics card users, you will need the GeForce Experience application.
If you have an AMD Radeon GPU, you can use the Radeon Adrenalin tool. If you do not have these tools, you can also update the graphics driver software, manually. The following is your procedure to install the latest version of the graphics driver software.
- Open the Device Manager (devmgmt.msc) on your computer. You can launch this window through the Start menu, Run utility (Windows + R), Control Panel, and the Quick Link menu (Windows + X).
- Click on the Display Adapters section to expand it into a set of graphics devices.
- Locate the dedicated GPU and right-click on it. It usually has the name of a popular GPU developer and the model name.
- In the context menu, select the Update driver option. This will open an update wizard.
- Choose the Search automatically for updated drivers option and if there are any updates available for the GPU drivers, they will be installed.
You will be required to restart the system so that the Operating System (OS) can install the updates onto the computer.
Install The Latest version of Java
The name of the game itself, Minecraft: Java Edition, implies that the game is powered by the Java language. Java plays a really important role in the functioning of the game.
Therefore, it is quite essential to update Java on your system, if you play Minecraft. You can download the Java for Minecraft setup from the Java website.
Updating Java for Minecraft can help fix existing bugs from the game script. Even though the game script refreshes and gets replaced anew, the game configurations do not change.
But this will affect the mods that are installed into the game as the new script can possibly get into a conflict with the mod scripts. You will have to add the mods into the game again to be able to play them after an update.
If you did not have this tool earlier, install it as soon as you can. This is because you will definitely need it, to be able to include OptiFine with the game.
Adjust The In-Game Video Settings
This solution is for computers with basic or mid-range graphics and other minimal specifications. If your PC is powerful, you can skip to the next step. Minecraft has a dedicated video settings category that can be used to adjust the quality of the video output produced by the game.
To adjust this aspect of the game, you just have to open the Minecraft game and go to Options > Video Settings. This page will have everything to do with the visual output of the game.
If you do not know the recommended settings for your system configuration, you can try to optimize the game. This can be done with the help of the NVIDIA GeForce Experience tool.
Here are the settings that we recommend you use on your game.
- Biome Blend: OFF (Fastest)
- Graphics: Fast
- Render distance: 2 chunks
- Smooth Lighting: OFF
- Max Framerate: Unlimited
- Use VSync: OFF
- View Bobbing: OFF
- GUI Scale: 3
- Attack Indicator: Crosshair
- Brightness: Bright
- Clouds: OFF
- Fullscreen: ON
- Particles: Minimal
- Mipmap Levels: OFF
- Entity Shadows: OFF
These settings should give you the fastest possible output on a mid-range computer with a resolution of 1920×1080 (24-bit).
Note: The Render distance can be adjusted according to your needs. You can keep it at a higher number of chunks or reduce it depending on the system configurations.
The higher your render distance is, the more time it takes to load the chunks far from you. This will make your game slow and you will have to wait for all the chunks in the Minecraft world to finish loading.
Remove & Reinstall Minecraft
The final solution for this issue is to get rid of the Minecraft game from your computer itself and re-install it again to start anew. When you remove the game from the system, only the save files are left behind.
The mods and the Optifine client will be removed from your computer. However, the texture packs and the shaders can stay on the computer, depending on where they were saved.
To uninstall the game, you have two options –
- The Add or Remove Programs page in Windows Settings
- Programs & Features page in the Control Panel
On these pages, you just have to locate, select, and click on the Uninstall option for the Minecraft game.
Once your computer no longer has the game installed, you can download the game from the Minecraft website after logging into your Mojang or Microsoft account.
Once the Minecraft setup is complete, you will have to log into the account again in the Minecraft Launcher. The game files will be downloaded and you can play the game without issues. You will also have to install OptiFine again if you wish to play with HD shaders.
You can also delete the Minecraft game data by going to the %appdata% directory, by opening it through the Run tool (Windows + R). This can reset the game data but you will lose all the saved game settings configurations and the saved Minecraft worlds. The necessary data will be obtained when the game is launched again.
This article contains all the assured solutions that you can use to fix the Minecraft OpenGL error: 1281 issue on your computer. If these steps do not help you, talk to Mojang support or OptiFine support. They could be of help to you. We hope this article was of help to you. Happy Mining and Crafting!
