Solution to the OpenGL 1281 error bug in Minecraft
Minecraft OpenGL is a game modification that attempts to make the game faster and smoother on the computer, reducing the rendering load on the system by “telling” the graphics card not to render anything that is not in the player’s direct view. Obviously, this is a compromise: less work for the graphics card, but more work for the processor.
Minecraft OpenGL 1281 bug
By default, this option is enabled so that users can enjoy better performance. Therefore, it is very common for users to encounter the “OpenGL Error 1281” error message. This error message is mainly related to the simultaneous execution of third-party variables and modules.
What causes the OpenGL 1281 bug in Minecraft?
If this error message appears while playing fully modified Minecraft, it’s likely that some mods are conflicting with your game. After our initial investigation, we concluded that some of the reasons why you might be experiencing this error are as follows:
Shaders: shaders are graphics settings that are usually user-entered into your modified Minecraft. If one of them is missing or corrupted, the game will display an error.
OptiFine: OptiFine is one of those third-party applications that try to improve Minecraft gameplay by giving users more control over the game. If it is not updated or in a problematic state, you will experience the OpenGL error.
Version Control: Minecraft is known to have problems if the forge and shader versions are not in sync with each other.
Java files. Normally all Java requirements are automatically installed by the game, but if they are omitted, this error will occur.
Before proceeding with the solutions, make sure you are logged in as an administrator on your computer and that you have an active and open Internet connection.
Solution 1: Delete all shadows
Shaders for Minecraft is an add-on for the game that allows players to set different terrains and settings. These are more like mini-modes that change the structure of the game, for example from winter to summer. Since shaders use all the resources of the app, they are known to conflict with other sections of the mod.
You should try disabling the existing shaders one by one and see which one solves the error message you are experiencing. Start with the last one you added to the game and work your way down. You can cut and paste the shadows elsewhere if you want to use them later.
Solution 2: OptiFine Update
OptiFine is an optimization tool for Minecraft that makes the game look better and faster. It also supports high-resolution textures and other modding configuration options. It allows users to speed up FPS, support shading, etc.
In short, this is the main driving force behind the interaction between mods. During our research, we have seen several cases where an older OptiFine application often causes an error message.
Check which version of OptiFine your Minecraft is using. If it’s older, you may want to navigate to the official OptiFine download page and install the latest version as soon as possible. Restart your computer before restarting the game.
Solution 3: Check mod version compatibility.
People who frequently encounter the OpenGL 1281 error have modified their Minecraft extensively and use more than one mod. If one of your mods is out of sync, that is, if the version of one mod is not compatible with the version of another mod, you will encounter this problem.
Therefore, you should check all mods installed on your computer and check their versions. If any of them has a mismatch, consider disabling the mod and try to launch the game. You can easily check the mod version compatibility from its official development website.
Solution 4: Manual installation of Java packages
Java file packages are a group of Java file directories that are used by various applications in their operations, including Minecraft. In fact, all the mods used in Minecraft are Java and if the Java file packages themselves are not installed on your computer, they will not start and will give you the error message. Here in this solution, we will install the Java files on your computer manually and check if the problem is solved.
1–Right click on This PC present on your Desktop and select Properties .
2- Now, in front of System Type check the type of operating system installed on your computer. If it is 32-bit, download the Java files and if it is 64-bit, download them from
3-Now extract the file you just downloaded to an accessible location. Open the folder and copy the version folder of the file you see.
4-Now press Windows + E to start Windows Explorer and navigate to the following path:
- C:N-Program Files-NJava (for 32 bit)
- C:N-Program Files (x86)N-Java (for 64 bit)
5-Now paste the file you copied into place. Be sure to copy the name of the folder we just pasted.
6-Now launch the Minecraft mod manager and click on Edit profile present at the bottom of the screen.
7-Now under Java Configuration (Advanced) , check the executable option and replace the correct path. In the image above, the file path we just pasted is set correctly.
8-Restart your computer and launch Minecraft again. Check if the problem is solved.
