How to Speed Up DeSmuME – Quick Guide

The realm of gaming has evolved dramatically with the rise of emulators, which allow individuals to play console games on different platforms. DeSmuME is one such emulator, specifically designed for Nintendo DS games.

While it is quite versatile and has a plethora of features, some users often find themselves wrestling with speed and performance issues.

In this extensive guide, we’re going to explore the ins and outs of how to speed up DeSmuME, ensuring that your gaming experience is seamless and enjoyable.


Gaming emulators have revolutionized the way we play and enjoy video games. They bridge the gap between various gaming platforms and our personal devices.

However, emulators, like any software, can sometimes underperform or not operate at their full potential.

For many DeSmuME users, the pressing question remains: How can we optimize its performance for an enhanced gaming experience?

Understanding the Factors that Affect Speed

Before we dive into the solutions, it’s essential to understand what might cause DeSmuME to lag or slow down:

  1. Hardware Limitations: If your computer’s specifications don’t meet DeSmuME’s requirements, you may experience slowdowns.
  2. Game’s Intrinsic Speed: Some games are inherently slower or have sections that are more demanding on the emulator.
  3. Settings Misconfiguration: Sometimes, the emulator’s settings may not be optimized for your specific game or hardware.

Optimizing Your Computer’s Performance

One of the primary ways to ensure that DeSmuME runs smoothly is to optimize your computer’s performance:

  1. Update Graphics Drivers: Ensure that your computer’s graphics drivers are up-to-date. Outdated drivers can significantly impede the emulator’s performance.
  2. Close Unnecessary Programs: Running several programs simultaneously can slow down DeSmuME. Close applications you don’t need.
  3. High-Performance Mode: Adjust your computer’s power settings to ‘High Performance.’ This will allow DeSmuME to utilize more of your computer’s resources.

Configuring DeSmuME Settings

Tailoring DeSmuME’s settings can drastically improve its speed:

  1. Frame Skip: In DeSmuME’s settings, you’ll find an option called ‘Frame Skip.’ This setting allows the emulator to skip certain frames, speeding up gameplay. However, use this sparingly as it can affect game visuals.
  2. 3D Settings: Adjust the 3D settings, ensuring that they’re set to ‘OpenGL.’ This makes use of your computer’s GPU, improving performance.
  3. Dynamic Recompiler: Enable the Dynamic Recompiler. This feature optimizes the emulation, making it run faster.
  4. Sound Settings: Sometimes, reducing the sound quality or disabling it can lead to a more fluid gameplay experience.

Choosing the Right ROM

The game ROM’s quality and source can influence DeSmuME’s performance:

  1. Official ROMs: Always ensure that you’re using official or well-reputed ROMs. Some unofficial ROMs can be poorly optimized, causing issues.
  2. Check Compatibility: Not all games are perfectly compatible with DeSmuME. Before playing, ensure that your game is known to work well with the emulator.

When All Else Fails: Consider Alternatives

If you’ve tried everything and DeSmuME is still not performing as expected, consider these alternatives:

  1. Try Another Emulator: There are other DS emulators available like ‘No$GBA.’ They might offer better performance for specific games.
  2. Use DeSmuME on Another Device: If you have access to another computer, especially one with better specs, consider running DeSmuME there.


How to speed up DeSmuME is a question with multiple answers. While one solution might work for some, others might need a combination of the strategies mentioned above.

The key is to understand the factors affecting performance, optimize both your computer and the emulator, and always use reputable game ROMs.

Gaming is about enjoyment, and with a smoothly running DeSmuME, your Nintendo DS gaming experience will be as delightful as ever.
