Mario Kart World and Nintendo Switch 2 Welcome Tour See Significant File Size Reductions Ahead of Release

Nintendo Optimizes Mario Kart World and Nintendo Switch 2 Welcome Tour File Sizes Before Launch With Nintendo Switch 2 on the horizon, Nintendo is taking proactive steps to ensure a streamlined experience for both new adopters and long-time fans.

Among the efforts to optimize upcoming game releases, two highly anticipated titles—Mario Kart World and Nintendo Switch 2 Welcome Tour—have undergone notable reductions in their final file sizes, as officially updated on the My Nintendo Store. Mario Kart World, set to launch as a premier racing title for the Nintendo Switch 2, will now require 21.9GB of storage space.

This change represents a 1.5GB decrease from its previously announced size of 23.4GB in April 2025.

The reduction may indicate Nintendo’s continued commitment to accessible storage management for users who will soon be transitioning to the hardware’s next generation. Similarly, Nintendo Switch 2 Welcome Tour, a title designed to showcase the new platform’s capabilities and onboard features, has seen its required file size trimmed from 2GB to 1.5GB.

These optimizations stand to benefit players by reducing the burden on internal storage, a critical consideration as modern games continue to grow in complexity and scale. Addressing the update, a representative summarised Nintendo’s approach: The company is focused on leveraging enhanced development tools and refining asset management processes to deliver high-quality gaming experiences without excessive storage demands. These file size reductions are especially welcome news for Nintendo Switch 2 users, as minimizing game data footprints becomes increasingly important with the proliferation of digital downloads and limited console storage.

Efficient file size management also helps improve download times and makes it easier for players to maintain a diverse library of titles on their hardware. As the Nintendo Switch 2’s release draws nearer, titles like Mario Kart World and Nintendo Switch 2 Welcome Tour demonstrate Nintendo's ongoing efforts to balance performance, graphical fidelity, and file size efficiency.

Both games will be accessible via the Nintendo eShop and will capitalize on the upgraded features offered by the new generation console.
