An overlay that with SaltyNX allows to set custom FPS in Nintendo Switch retail games.

You can see the video how it works (with Witcher 3 dynamic resolution config mod to make anything above 30 FPS available).

Note: Tool is utilizing detection of graphics API to manipulate FPS, and in special cases it requires using patches made per game for each version to get more than 30 FPS. You can find those patches here. Max supported yaml size is 32kB, though it can be expanded in the future.

Installation

Requirements:

Atmosphere CFW is required. SX OS and other CFWs are not supported. It's advised to use Atmosphere's USB Transfer Tool homebrew to transfer files. If you use Hekate's USB Mass Storage and you will be putting files using any other Operating System than Windows, you must run Hekate's Archive Bit Fixer after putting all files.

To install:

  • Download SaltyNX, copy the folders SaltySD and atmosphere to the root of your SD card, accept any popup about overwriting folders.
  • Download nx-ovlloader, copy atmosphere folder to the root of SD card, accept any popup about overwriting folders.
  • Download Tesla Menu, copy switch folder to the root of SD card, accept any popup about overwriting folders.
  • Download Status Monitor Overlay, copy Status-Monitor-Overlay.ovl to switch\.overlays folder. It may not be visible in USB Mass Storage, but it's there.
  • Download FPSLocker, copy FPSLocker.ovl to switch\.overlays folder. It may not be visible in USB Mass Storage, but it's there.
  • Download sys-clk, copy all 3 folders to the root of SD card, accept any popup about overwriting folders.
  • Restart Switch, now you can access overlays by pressing all 3 buttons at once: L, D-Pad Down and Right Stick (aka pressing it).

Additionally for FPSLocker download newest set of patches from FPSLocker Warehouse for games that need more things to be tweaked to get proper FPS boost.

User guide

Overlay runs in two modes:

  • When game is running.
  • When game is not running.

When game is running

If game is supported by SaltyNX and you installed everything correctly, you will see menu where first line states NX-FPS plugin is running. Explanation of each line:

  • Interval Mode - it's used by NVN API to set limiter to either 30 FPS (2) or 60 FPS (1).
  • Custom FPS Target - it's used to lock game to certain FPS. If game is using engine proprietary FPS locks, it may not be able to unlock more than 30 FPS without additional patches.
  • Big number on the right - it shows how many frames have passed in last second for currently running game. This is to confirm that lock is working as expected.
  • Increase/Decrease FPS target - Change FPS Target by 5. Minimum is 15 FPS, max is 60 FPS. If FPS is set above 30 FPS, it sets interval mode to 1. Otherwise it sets interval to 2.
  • Disable custom FPS target - Removes FPS Target. Since we cannot predict what interval mode is expected at this point, it is in user's discretion to manipulate FPS to bring back correct interval before disabling FPS target.
  • Advanced settings - submenu which consists of:
    • If game is using NVN
      • Window Sync Wait - this is dangerous setting that disabled can crash game, but in some can bring benefit of disabling double buffer vsync at the cost of small graphical glitches (check list of games compatible with this solution at the bottom of README). Use it with caution. It won't show if game is not using double buffer.
      • Set Buffering - if game is using any other buffering than double, this option will show that will allow you to force game to run at any other buffering that is not higher than original one (so f.e. you cannot change double buffer to triple buffer). Lowering buffer is recommended only for games that have near perfect performance at 30 or 60 FPS, but suffer from bad framepacing or big input lag. If you will force double buffer in games with uneven performance, FPS drops will be very severe. It can be applied only at boot of game, so after changing buffering you must save settings in FPSLocker and restart game.
        • Explanation of Set/Active/Available Buffers:
        • Set - how many buffers were set by using nvnWindowSetNumActiveTextures. If game is not using it, it will be 0. It can be used by games to set lower buffer value than reserved space allows. If this is detected to be used and lower than Available Buffers, you can use "(force)" variant next to default option. Without (force) it will reset to default settings.
        • Active - How many buffers are actually used by game.
        • Available - How many buffers is actually provided to NVN. We can use this information to force games to utilize all buffers when they are not doing it.
    • Convert config to patch file - if proper config file exists for this game and version, you will get an option to convert it to patch file that will be loaded when you will run this game next time. Patch is saved to SaltySD/plugins/FPSLocker/patches/*titleid_uppercase*/*buildid_uppercase*.bin
    • Delete patch file - if proper config file exists for this game and version, you will get an option to delete patch file so it won't be loaded when you will run this game next time.
    • Check/download config file - Checks in Warehouse repository if config for this game and version exists. If exists, it is downloaded and also checked if it's the same as the one on sdcard. If it's not, overlay will remove existing patch and config file, and user must manually convert new config to patch file. 0x312 error means we got unexpected file from github. Any other error code means that something is happening with your connection or github server.
  • Save settings - save profile for currently running game that will be loaded next time by plugin on boot automatically. Don't use it if you disabled Sync Wait and you didn't test it properly that it won't cause crash. Profile is saved in SaltySD/plugins/FPSLocker/*titleid_uppercase*.dat
  • Display settings - submenu available only for non OLED model users. Consists of:
    • Increase refresh rate - change display refresh rate up to 60 Hz.
    • Decrease refresh rate - change display refresh rate down to 40 Hz.
    • Display Sync - When turned on, both options above are not available, display refresh rate is changed only when game is running, and matches refresh rate with FPS Target. In case if FPS Target is below 40 FPS, refresh rate is restored to 60 Hz.

When game is not running

You will have two submenus to choose from (if you are using OLED model, you will be redirected automatically to Games list):

  • Games list

It will list installed games (max 32) and as first option it's available "All" submenu.
Inside each one you will find two options:

    • Delete settings - it will delete file created by "Save settings" option
    • Delete patches - it will delete file created by "Convert config to patch file" option
  • Display settings - submenu available only for non OLED model users. Consists of:
    • Increase refresh rate - change display refresh rate up to 60 Hz.
    • Decrease refresh rate - change display refresh rate down to 40 Hz.
    • Display Sync - change display refresh rate only when game is running, match refresh rate with FPS Target. In case if FPS Target is below 40 FPS, refresh rate is restored to 60 Hz.

Sync Wait

Games where you can disable double buffer vsync by turning off Window Sync Wait in FPSLocker:

  • Batman - The Telltale Series (Warehouse patch enables triple buffer, so there is no need to use this option)
  • Pokemon Legends: Arceus
  • Pokemon Scarlet
  • Pokemon Violet
  • Sonic Frontier
  • The Legend of Zelda: Tears of the Kingdom
  • Xenoblade Chronicles: Definitive Edition
  • Xenoblade Chronicles 2
  • Xenoblade Chronicles 3
