If you're looking to collect FPS data in Nintendo Switch games, NX-FPS is a great SaltyNX plugin to consider. To get started, you'll need to install my fork of SaltyNX 0.5.0+ from here.

Once you've installed the necessary software, simply put the NX-FPS.elf file into /SaltySD/plugins. This plugin currently supports graphics APIs such as NVN, EGL, and Vulkan.

To read FPS data from the plugin, you can either use the Status Monitor Overlay 0.8.1+ from [1] or write your own code. If you're interested in writing your own code, I've provided instructions based on the Status Monitor Overlay code:

You'll need to include the old ipc.h file from [2] as well as SaltyNX.h from [3].
Connect to SaltyNX SharedMemory by connecting to SaltyNX, retrieving the SharedMemory handle, terminating the connection with SaltyNX, and then assigning SharedMemory to your homebrew.

Troubleshooting

Q: Why I got constantly 255?
A: 255 is default value before plugin starts counting frames. This may be a sign that:

Game is using different API or function than what is currently supported
Plugin missed symbol when initializing (for whatever reason)

Try first to run game again few times. If it's still 255, make an issue and state name of game. Next updates will include support for other graphics APIs.
