How to Install Vulkan Mod in PojavLauncher

How to Install Vulkan Mod in PojavLauncher (Easy Methods for Any Player)

If your Minecraft on PojavLauncher is not working, crashing or showing low FPS, don’t worry enabling Vulkan mode can give you smoother gameplay and 20–40% more FPS on many Android phones. In this guide, I will tell you how to install the Vulkan mod in PojavLauncher in a simple and easy way, even if you are a beginner. Vulkan is a modern graphics API that lets Minecraft run faster and with fewer glitches on many devices.

There are two ways to install it.

  1. Enable “Vulkan as a graphics renderer” directly in PojavLauncher, or
  2. Install “VulkanMod .jar with Fabric Loader and Fabric API” (for advanced users).

On many Android devices, enabling Vulkan (in any way) can give 20–40% more FPS and smoother gameplay. This guide explains both methods in simple steps, so even a beginner can follow them.

What Are We Actually Doing?

  1. Switching to Vulkan graphics mode
    1. PojavLauncher has a “Vulkan / OpenGL renderer option” in settings.
    2. This allows Minecraft to use Vulkan instead of the old OpenGL, which is lighter and faster on many phones.
  2. Installing the VulkanMod .jar via Fabric
    1. Some players use a special “VulkanMod mod” from Modrinth.
    2. This mod needs “Fabric Loader” and “Fabric API” to run.
    3. It unlocks extra Vulkan related options in Minecraft.

You can choose one method or try both but i will suggest you, use only one at a time on weak phones.

Method 1: Enable Vulkan Graphics Mode in PojavLauncher

This method is easiest and safest for most players.

Step 1: Check If Your Phone Supports Vulkan

First, confirm your phone can use Vulkan:

  1. Open Play Store.
  2. Search “Vulkan Info”.
  3. Install any Vulkan Feature Info app.
  4. Open it and check the result.

If it says “Vulkan is supported”, you can use Vulkan.
If it says “Vulkan not supported”, Vulkan will not help you much.

Step 2: Update PojavLauncher

Use the latest version of PojavLauncher

  1. Download the newest PojavLauncher APK from the official GitHub or any other trusted site.
  2. Tap the APK -> Allow “Install from unknown sources” -> Complete install.
  3. Open PojavLauncher and make sure it is working.

Older versions may not support Vulkan properly and can crash.

Step 3: Add a Minecraft Version

Vulkan plays an important role in how Minecraft renders its graphics, which means your device needs proper Vulkan support to run the game smoothly.

  1. Inside PojavLauncher, add a Minecraft Java version (1.16.5, 1.17, 1.18, or the latest Pojav supports).
  2. Create a new profile for that version.
  3. First, run Minecraft with OpenGL (default) to check it opens without crashes.

Step 4: Turn On Vulkan Renderer

Now enable Vulkan in PojavLauncher

  1. Open PojavLauncher.
  2. Go to Settings.
  3. Scroll to Graphics / Renderer / OpenGL settings.
  4. Look for options like:
    1. “Use Vulkan”
    2. “Enable Vulkan”
    3. “Render API” with choices: OpenGL, Vulkan, Auto
  5. Choose Vulkan or turn “Use Vulkan” on.
  6. Save settings and close the menu.

Now PojavLauncher will try to run Minecraft using Vulkan graphics instead of OpenGL.

Step 5: Test Minecraft with Vulkan

Test if Vulkan is working:

  1. Open your Minecraft profile.
  2. Tap Play and let the game load.
  3. If the game runs smoothly and FPS looks better, congratulations your Vulkan is active.

If you get black screen, crash, or lag, try

  1. Turn off the Vulkan.
  2. Lower the resolution or FPS limit.
  3. Use a different Minecraft version.

Follow each and every step and you are good to go.

Method 2: Install VulkanMod .jar with Fabric (Advanced)

If you want to use the VulkanMod mod from Modrinth, here is how to do it safely.

Step 1: Install Fabric Loader in PojavLauncher

  1. Open PojavLauncher.
  2. Go to Installations / Add version.
  3. Choose a Fabric version that matches your Minecraft version (e.g, 1.18 Fabric, 1.20 Fabric).
  4. Install that Fabric version.
  5. Create a new profile and select Fabric as the loader.

Now your Minecraft will run via Fabric, not just the normal launcher.

Step 2: Download Fabric API and VulkanMod .jar

You will need two files:

  1. Fabric API
    1. Go to the Fabric website or Modrinth.
    2. Download the Fabric API .jar for your exact Minecraft version.
  2. VulkanMod .jar
    1. Open Modrinth and search “VulkanMod”.
    2. Download the “VulkanMod .jar file” that matches your Minecraft version.

Save both the files in a place where you can find them easily.

Step 3: Place the .jar Files in the Mods Folder

  1. Open a file manager on your phone (like Files by Google, X‑plorer, etc.).
  2. Enable “Show hidden files” in the file manager settings.
  3. Navigate to:
    1. Android/data/net.kdt.pojavlaunch/files/.minecraft/mods
  4. Copy both:
    1. fabric-api-<version>.jar
    2. vulkanmod-<version>.jar
      into the mods folder.

If the mods folder does not exist, create it yourself.

Step 4: Launch Minecraft with the Fabric Profile

  1. Open PojavLauncher.
  2. Select the Fabric profile you created.
  3. Tap Play and wait for the game to load.

If everything is correct, the VulkanMod will be active in the background.

Step 5: Verify VulkanMod Is Working

Inside Minecraft:

  1. Press F3 or Fn + F3 if your keyboard needs it.
  2. Look for any Vulkan‑related lines or extra info in the debug screen.
  3. Or open Video Settings and see if new Vulkan options appear.

If the game crashes or Vulkan options don’t show try:

  1. Checking that Minecraft version = Fabric version = Fabric API version = VulkanMod version.
  2. Removing the “VulkanMod .jar” and testing only Fabric + Fabric API first.

Tips for Better Performance

  1. On weak phones, avoid Vulkan + many shaders + many mods at once.
  2. If Vulkan causes crashes, turn it off and stick to OpenGL or Fabric without VulkanMod.
  3. After Android updates, recheck your Vulkan settings; they sometimes reset.

FAQs

Q: What does “Vulkan mod” mean in PojavLauncher?
A: It can mean two things, Using Vulkan as a graphics renderer in PojavLauncher, or Installing the VulkanMod .jar with Fabric Loader for extra options.

Q: Which method is better: Vulkan renderer or VulkanMod .jar?
A: Vulkan renderer is easier, faster, and safer for most players while “VulkanMod .jar” is for advanced users who want more control and extra settings.

Q: What if my phone doesn’t support Vulkan?
A: If the Vulkan Info app says “not supported”, Vulkan methods won’t help much. Focus on lower resolution, fewer mods, and optimized settings instead.

Q: Do I always need Fabric and Fabric API?
A: Only if you use the VulkanMod .jar from Modrinth. If you only enable Vulkan graphics in PojavLauncher, you don’t need Fabric at all.

Q: Can Vulkan make Minecraft crash more?
A: Yes, on some devices or with wrong versions, Vulkan can cause crashes. If this happens, turn Vulkan off or remove the VulkanMod .jar temporarily.
