The OpenGL option in Minecraft is meant to lessen the strain on your computer’s hardware by “instructing” the GPU to skip rendering objects that aren’t in the player’s field of view. Naturally, this means less work for your GPU but more stress on your CPU.
Method 1: We’re Getting Rid of All The Shaders.
Minecraft shaders are an add-on that expands the game’s visual customization options. In reality, they are more akin to miniature game hacks that alter the overall feel of the game by altering its atmosphere, such as by making it feel more like summer instead of winter.
Shaders are notorious for causing incompatibilities with other mod modules because they consume all of the system’s resources. In order to determine which shader is causing the error, you should temporarily disable all of them.
You should begin with the one that was just added and work your way down. The shaders can be copied and pasted to another location for future usage.
Method 2: OptiFine Upgrade
OptiFine is a Minecraft add-on that enhances the game’s visual quality and increases its overall performance speed. The game fully supports high-definition textures and other parameters crucial to modification. It supports shaders, gives users an FPS boost, and more.
This can be thought of as the fundamental impetus for your mods and their interactions with one another. Our investigation revealed that the error message is typically brought on by using an out-of-date version of OptiFine.
Ensure you’re using the most recent version of OptiFine for Minecraft. You should consider updating to the newest version of OptiFine as soon as possible if you’re using an older one from the official download page. Please restart your computer and then try to open the game again.
Method 3: A Compatibility Check for Add-Ons
Those who run into OpenGL Error 1281 have likely done substantial modding to their Minecraft installation and are utilising many Mod modules. This problem occurs when two or more of your modules are not up to date with one another.
As a result, you should verify the versions of all the add-ons you have installed. If there is a discrepancy, you can try launching the game without the mod and seeing if it helps. The mod’s official developer website makes checking version compatibility a breeze.
Method 4: Managing Java Package Installations By Hand
Packages of Java files are collections of directories containing Java code that are utilised by many programmes, including Minecraft. In fact, all Minecraft mods are written in Java, therefore if you don’t have the Java runtime environment set up on your computer, you’ll get an error notice when you try to initialise the modules.
To see if this resolves the problem, we’ll need to manually install the Java files on your machine.
Step 1: The This-PC icon on the desktop can be accessed by right-clicking and selecting Properties.
Step 2: Now, in the System type field, select the OS version currently running on your machine.
Step 3: First, save the downloaded archive somewhere convenient, and then run the included extractor. To make a copy of the file version folder, open the folder.
Step 4: Then, open Windows Explorer by pressing Windows + E and going to this location:
C:\Program Files\Java (for 32 bit)
C:\Program Files (x86)\Java (for 64 bit)
It’s time to paste the file you copied there. Take note of the folder’s name, which we’ve just pasted.
Step 5: Click the “Edit profile” button at the very bottom of the Minecraft mod manager’s interface.
Step 6: Now, in the “Java settings” submenu, select “Executable,” and set the appropriate path. The picture above shows the right file path after we pasted it.
Step 7: It sounds like you need to restart your computer and then start Minecraft over again. See whether the problem still exists.
