The long-awaited Nintendo Switch 2 is finally in my hands.
The Switch 2 introduces a new mouse mode, where you simply hold the Joy-Con 2 on a surface like a mouse, and a cursor appears on the screen, similar to the Lenovo Legion Go released two years ago. However, my first impression of the Switch 2’s mouse mode is—laggy! Extremely laggy! It’s even laggier than my already high-latency Bluetooth mouse.
To prove this, I used the 480fps slow-motion camera on my OnePlus 13 to conduct a simple test comparing the Joy-Con 2 with my Logitech MX Anywhere 3. The test measured the number of frames from when the mouse “starts moving” to when the screen “shows a change.” In more professional tests, you’d also measure the input latency “after” the mouse starts moving, but due to my basic testing setup, I couldn’t do that.
The test results are as follows:

Test Method: Place the mouse on a surface, give it a light push to wake it up (though it didn’t seem necessary), then push it harder a second time. The actual measurement is the number of frames captured by the slow-motion camera from when the mouse starts moving the second time to when the screen shows a change (cursor begins to move).
Notes:
1. On the Home Screen, Joy-Con 2 (L) was attached to the console, while only Joy-Con 2 (R) was detached. In the Welcome Tour, both Joy-Con 2 units were detached.
2. In test runs 1 and 2 for the Switch 2, the Joy-Con 2 straps were not attached, while in test runs 3 and 4, the straps were attached. It appears that the presence of the straps has little impact on input latency.
As you can see, the input latency of the Joy-Con 2’s mouse mode is about 1.7x higher than my non-gaming Bluetooth mouse, making it nearly unusable for shooting games. If you tried using mouse mode to play non-exclusive FPS games on the Switch 2, you’d likely get destroyed by PC players.
