How to Make Prism Launcher Use a Dedicated Graphics Card for Optimal Minecraft Performance

In recent years, gaming has evolved to demand more power and better hardware performance. For Minecraft enthusiasts, ensuring the best gameplay experience is crucial. If you’re using Prism Launcher to play Minecraft and notice lag, poor frame rates, or slow performance, the issue may lie in your computer’s graphics settings. By default, your system might be using an integrated graphics card, which isn’t powerful enough for high-performance gaming. This article will guide you through ensuring that Prism Launcher uses your dedicated graphics card, leading to smoother gameplay and better overall performance.

Introduction to Prism Launcher and Dedicated Graphics Cards

Prism Launcher is a popular tool used by Minecraft players to manage multiple game instances and mods. While it’s great for organization, you may encounter performance issues if your system defaults to using an integrated GPU (Graphics Processing Unit) instead of a dedicated one. Integrated GPUs are designed for basic tasks such as web browsing or watching videos but fall short when it comes to rendering intensive games like Minecraft.

On the other hand, dedicated graphics cards, such as those from NVIDIA and AMD, are designed to handle graphically demanding games and applications. To maximize your Minecraft performance, it’s essential to ensure Prism Launcher is using the dedicated GPU rather than the integrated one.

In this guide, we’ll show you how to switch Minecraft, through Prism Launcher, to use the dedicated graphics card on Windows, Linux, and MacOS, ensuring a better gaming experience.

Why Minecraft Needs a Dedicated Graphics Card

Minecraft might look simple with its blocky, pixelated graphics, but don’t be fooled — it’s a resource-heavy game that needs a lot of processing power. Here’s why using a dedicated GPU is so important:

• Better Frame Rates: A dedicated GPU can significantly improve the frame rates in Minecraft, giving you a smoother and more immersive gaming experience.
• Faster Rendering: Whether you’re loading chunks of land, or using mods with high-resolution textures, a dedicated GPU can handle the heavy rendering load much more effectively.
• Reduced Lag: Using an integrated GPU might cause lag, especially when you’re running multiple mods or shaders in Minecraft. A dedicated GPU reduces the likelihood of these performance issues.
• Increased Stability: Dedicated GPUs have more video memory (VRAM) and are better at handling the game’s graphical demands without freezing or crashing.

Now that you understand the importance of a dedicated GPU, let’s move on to checking whether your system is using the correct graphics card and how to switch it if needed.

Step 1: Checking Which GPU Prism Launcher is Using

Before making any changes, it’s important to check whether Minecraft is running on the dedicated GPU or the integrated one. Here’s how you can do that.

For Windows Users:

1. Open Minecraft through Prism Launcher and join any world.
2. Press F3 on your keyboard. This will bring up the Minecraft Debug Screen.
3. On the right-hand side, look for the “Display” line. This will tell you which GPU is currently in use. If it shows your integrated GPU (like Intel HD Graphics), you’ll need to change it to your dedicated one (e.g., NVIDIA or AMD).

For Linux Users:

1. Open a terminal window.
2. Type the command glxinfo | grep “OpenGL renderer” and press Enter.
3. The output will show which graphics card is being used. If it’s your integrated GPU, you’ll need to switch it to the dedicated one.

For Mac Users:

1. Go to the Apple Menu and select About This Mac.
2. Click on the System Report button.
3. Under Graphics/Displays, you’ll see which GPU is active. If it’s your integrated GPU, follow the steps below to switch to your dedicated one.

Step 2: How to Force Prism Launcher to Use a Dedicated GPU

If Minecraft is using the integrated GPU, it’s time to make sure Prism Launcher runs the game on your dedicated graphics card. The process differs depending on your operating system, so we’ve broken it down for Windows, Linux, and MacOS.

For Windows Users:

1. Access Graphics Settings:
   • Open Windows Settings and go to System > Display.
   • Scroll down and click on Graphics settings.
2. Add Prism Launcher to the List:
   • Under Custom options for apps, click Browse.
   • Navigate to where your Java executable is located. You can find this in the Prism Launcher Settings under Java.
   • Select the javaw.exe file (this is the Java Runtime that Minecraft uses) and click Add.
3. Set High Performance:
   • Once Java is added to the list, click Options and choose High performance. This ensures that Minecraft will use your dedicated GPU for optimal performance.
4. Apply the Settings:
   • Save the settings, restart your computer, and launch Minecraft through Prism Launcher. You should now notice better performance with Minecraft running on the dedicated GPU.

For Linux Users:

Linux users often face challenges when dealing with hybrid GPU setups (both integrated and dedicated GPUs). Here’s how you can force Minecraft to use your dedicated GPU.

1. Install NVIDIA/AMD Drivers:

Ensure that you have the latest drivers for your dedicated GPU installed. Use the following command to install the correct drivers:
Copy code
sudo apt install nvidia-driver-460

For AMD, use:
Copy code
sudo apt install mesa-vulkan-drivers

2. Use optirun or primusrun:

For NVIDIA users with Bumblebee, run Minecraft with the following command:
Copy code
optirun prism-launcher

Alternatively, use primusrun for a more energy-efficient option:
Copy code
primusrun prism-launcher

3. Set Up NVIDIA Profiles:
   • Open the NVIDIA X Server Settings and create a profile for Minecraft or Java.
   • Set it to use the dedicated GPU, ensuring better performance when Minecraft runs.

For Mac Users:

MacOS has dynamic GPU switching, but if you want to force Minecraft to use the dedicated GPU, follow these steps.

1. Disable Automatic Graphics Switching:
   • Go to System Preferences > Energy Saver.
   • Uncheck the box for Automatic Graphics Switching. This ensures that the system always uses the more powerful dedicated GPU.
2. Check GPU Usage:
   • To verify that Minecraft is using the dedicated GPU, open Activity Monitor and go to the Energy tab. Look under Requires High Perf GPU to ensure that Minecraft is listed.

Step 3: Troubleshooting Common Issues

If Minecraft is still using the integrated GPU after following the steps above, here are some troubleshooting tips:

• Double-check GPU Settings: Ensure you’ve correctly added the Java executable for Minecraft in your system’s graphics settings.
• Update Drivers: Make sure both your integrated and dedicated GPU drivers are up to date. Outdated drivers can prevent the dedicated GPU from functioning correctly.
• Reinstall Prism Launcher: If the problem persists, try reinstalling Prism Launcher and re-configuring the graphics settings.

Step 4: Additional Tips for Optimizing Minecraft Performance

Using a dedicated GPU is just one part of optimizing your Minecraft experience. Here are some additional tips to boost performance:

• Use Optimization Mods: Mods like OptiFine can greatly enhance Minecraft’s performance by providing better graphics optimization and more control over game settings.
• Adjust In-game Settings: Lowering the render distance, turning off fancy graphics, and minimizing particle effects can improve performance, especially on lower-end systems.
• Manage Background Applications: Close unnecessary programs running in the background to free up system resources for Minecraft.

Best Practices for Keeping Your Drivers and Software Updated

Keeping your drivers up-to-date ensures that you’re getting the best performance out of your GPU. Both AMD and NVIDIA frequently release updates that optimize performance for popular games. Here’s how to update your drivers:

• NVIDIA Users: Open the GeForce Experience application and check for driver updates regularly.
• AMD Users: Open the AMD Radeon Software application and check for updates under the Driver tab.

Conclusion

By ensuring that Prism Launcher uses your dedicated graphics card, you can significantly improve Minecraft’s performance. Whether you’re a casual player or a hardcore modder, this simple change can make all the difference in your gameplay. Follow the steps for your operating system, and you’ll enjoy smoother, faster Minecraft sessions.

Now that you’re equipped with the knowledge to optimize your Minecraft experience, dive back into the blocky world and enjoy lag-free gaming!
