I'll show you how to install OptiFine for Minecraft version 1.21.4
First, follow the link.
Click on Download opposite the required version.
Now wait for 5 seconds.
And click the skip button.
And click download again.
We will also need Forge of the required version.
After installing Forge, we just need to move OptiFine to the mods folder.
Or you can install it separately, but then it will be without mods.
And that's it.
All we need to do is drop the shaders into the shaders folder and we can turn them on.
As you can see, everything works.
Thank you for watching. And goodbye.
