| Dolphin's new low latency options can provide less lag than original GameCube hardware. |
For over two decades, the Dolphin Emulator has stood as the pinnacle of Nintendo GameCube and Wii preservation, allowing generations of games to live on long after their original hardware has faded from store shelves. Yet, one persistent ghost has haunted even the best software emulation: input latency. That nagging, split-second delay between pressing a button and seeing the action on screen has always been the final barrier between a good emulation experience and a truly authentic one.
Until now. In a stunning technical breakthrough, the developers of the open-source Dolphin project have not just matched the responsiveness of original Nintendo hardware—they have surpassed it. This leap forward is a game-changer, particularly for the competitive fighting game community and purists who still swear by the feel of a CRT monitor.
The Latency Problem: Why Original Hardware Still Felt Snappier
For the uninitiated, input lag is the hidden tax of modern gaming. Every step between your controller and the pixels on your screen—be it processing in the console, signal conversion, or the refresh cycle of your display—adds precious milliseconds. Software emulation, by its very nature, adds more layers. It must mimic the behavior of entirely different hardware, often creating a perceptible "mushy" feel compared to the instant response of a native GameCube or Wii.
This issue is exacerbated on platforms like Android and budget handhelds. Even official solutions aren't immune. Notably, the Nintendo Switch Online version of GameCube games has been criticized for its high latency, which, until very recently, was worse than Dolphin's previous benchmarks. While Nintendo has made improvements, the experience still lags behind the original consoles.
Breaking the Barrier: How Dolphin Did It
The Dolphin development team, in collaboration with two key figures in the retro gaming hardware scene—Fizzi, the creator of the revolutionary Slippi netplay service for Super Smash Bros. Melee, and Arte, who developed a ultra-low latency GameCube controller adapter—conducted rigorous testing to prove their claims.
The results, measured on a CRT for a baseline, are revolutionary:
- Original GameCube on CRT: 62 ms (the gold standard for responsiveness)
- Dolphin (New Defaults, 144Hz Monitor): 56 ms
- With "Rush Frame Presentation": 53.3 ms
- With "Immediately Prevent XFB": 37 ms
That final number is the headline. At 37 milliseconds, Dolphin with its new experimental feature is dramatically faster than the original hardware it's emulating. The team's detailed methodology and full breakdown of these groundbreaking changes can be found in their latest progress report.
For a deep dive into the technical marvels behind this update, including the new latency features and the addition of RetroAchievements support on Android, read the full Dolphin Progress Report for December 2025.
It’s worth noting that the "Immediately Prevent XFB" feature, while revolutionary for latency, can cause graphical glitches in some games and isn't recommended for general use. The new default settings, however, offer a significant and reliable improvement for everyone.

What About "Slippi Melee Hacks"?
Eagle-eyed viewers of the benchmark charts will see "Slippi Melee Hacks" posting an even more incredible latency figure. This isn't a standard Dolphin build, but a specialized, modified version of both the emulator and Super Smash Bros. Melee itself, engineered from the ground up for flawless online competitive play. It serves as a proof-of-concept for how far optimized emulation can be pushed.
The Slippi project continues to be a driving force in the Melee community, as highlighted in their recent updates.
The team behind Slippi shared their excitement about these underlying improvements, noting their potential impact on the competitive scene.
The Future Feels Faster
This achievement redefines what's possible in emulation. It’s not just about playing old games in higher resolutions; it’s about creating an experience that can be better than the original in one of the most tactile aspects: feel. The next great hope is for these latency reductions to be fully implemented in Dolphin for Android. This would supercharge devices like the AYANEO Pocket V and other emulation-focused handhelds, finally delivering console-perfect responsiveness on the go.
For now, PC users can download the latest development build and feel the difference for themselves. The ghost of input lag has finally been exorcised, and the future of retro gaming emulation has never felt more responsive.
