Switch 2 GameChat Strains System Resources, Experts Find

Digital Foundry's tech analysts have disclosed the finalized technical specifications for the Nintendo Switch 2, noting that the GameChat feature reportedly consumes a "significant portion" of system resources, leading to concerns among developers.

Last month’s Nintendo Direct presentation introduced the GameChat feature for the Switch 2, activated by pressing the C button on the new Joy-Con controllers.

This function allows players to watch each other’s gameplay—whether they’re playing the same or different titles—and with an integrated camera, they can even see one another. The built-in microphone works reliably across various gaming environments, making communication seamless. The C button’s dedicated chat menu aims to deliver an all-in-one multiplayer experience, potentially making this Nintendo's most impactful online feature in years.

According to Digital Foundry, Nintendo supplies developers with a GameChat testing tool that simulates real-world API latency and L3 cache misses caused by the feature. This enables developers to evaluate performance without running active GameChat sessions.

The question remains whether enabling or disabling GameChat has a noticeable impact on in-game performance for players. If GameChat operates within its allocated resources, there should be no difference. However, the availability of Nintendo’s emulation tools suggests some performance impact exists, requiring developers to test accordingly.

As Digital Foundry stated: "We're curious to see how GameChat might affect gameplay performance, as this appears to be a point of concern for development teams." A definitive answer will only come when the Switch 2 launches on June 5.

Separately, Digital Foundry shared final tech details for the Switch 2. The system reserves 3GB of memory, leaving 9GB available for games. By comparison, the original Switch reserved 0.8GB, with 3.2GB for games. This means a notable portion of the Switch 2’s resources is dedicated to the system. As with most consoles, developers do not have full access to GPU resources, as some are reserved for system operations.

The Switch 2 includes a 7.9-inch wide color gamut LCD display capable of 1080p (1920x1080) output. This marks a significant improvement over the original Switch’s 6.2-inch screen, the Switch OLED’s 7-inch display, and the Switch Lite's 5.5-inch screen.

It also supports HDR10 and Variable Refresh Rate (VRR) up to 120 Hz, enabling games to run at up to 120fps, depending on the title and your setup.

When docked, the Switch 2 can output games at 4K (3840x2160) and 60fps, or at 1080p/1440p (1920x1080/2560x1440) and 120fps. These enhanced graphics are powered by a "custom NVIDIA processor."
