An overlay that with SaltyNX 0.8.0+ allows to set custom LCD refresh rate and FPS in Nintendo Switch retail games.

Disclaimer: Tool is utilizing detection of graphics API to manipulate FPS. It supports special patches that are helping with going above 30 FPS in games using proprietary FPS locks.

You can see here how it works (I was utilizing Witcher 3 dynamic resolution config mod to make anything above 30 FPS available):

Don't sleep on the refresh rate change - honestly this a huge deal. So many games on Erista at 1020/537/1996 on battery (with undervolt + tightened ram timings) you can get a beautiful 40fps at 40hz and it is so much smoother than 30fps as 40fps is frametime halfway between 30 and 60fps. So you are getting 50% more smoothness for a 33% performance cost.

On Mariko (besides OLEDs lol) in handheld (1963/998/2400 on battery with undervolt and tightened ram timings) I want to play handheld at 60fps at 720p without dropping res but now I can drop framerate to 40 or 45fps and get a beautiful image with docked resolution (I.e. things like Hogwarts Legacy, Lego 2K Drive, Princess Peach Showtime, Crash N Sane Trilogy, Sonic Frontiers). Now we can really get best of both worlds. 45fps looks scarily close to 60fps now.

As a bonus this also fixes some questionably programmed Unity games from stuttering if you set Hz to 50 (Pac-Man World Repac and Super Monkey Ball Banana Rumble) because they both update their camera internally at 50fps instead of 60fps. 50fps on 60hz looks awful but 50fps on 50hz looks great. This might benefit more Unity games as well (tell me and no it doesn't fix Final Fantasy Stutter Remasters)

And the cherry on top is that this heavily benefits double buffer games (i.e. Can't maintain 60fps drops to 30fps now turns into can't maintain 45fps drops to 22.5fps. Helps stuff like Xenoblade series get 60FPS.)

Thanks for masagrator for letting me test this and the rest of the 60FPS discord. He went to a lot of trouble to update a whole bunch of patches to fix issues. I am amazed by how much Switch Homebrew keeps evolving and don't even know what's left at this point.

this is maybe a completely stupid question, but can any of this, maybe the patches, work on emulator?

No emulator supports FPSLocker configs.

With newest SaltyNX release now you can set perfectly adjusted LCD refresh rate.

That means that we can adjust LCD refresh rates without bugs or glitches? Thank you for your tool, it's amazing.

Any advance in oled?

Ehehe , I think 40 hz its really a game changer for the switch. Do you think is possible to change the output to the tv to 120hz? If the output is 120hz with gane at 40 fps it will run smooth. Some game in ps5 do this. Btw you guys are awesome thanks for the great work .

Nobody figured out how to do it on HOS.

Maybe they don’t have the option hide in the HOS. Do you have some early build that don’t exclude oled switch’s or you didn’t released? Just curious if mine will work or not. Ehehe

Are there any inherent risks to adjusting the refresh rate downwards on an LCD Switch? I can understand "overclocking" the refresh rate to be risky, but I'd assume lowering is should be safe? The warning given before accessing that screen wigged me out.

And that's good. I don't want people to use it thinking it's 100% safe as theoretically there are risks with stuck and dead pixels, but nobody reported such issue so far. I'm setting my display to 45 Hz whenever running game at 60 FPS requires heavy overclocking and no issue popped out.

You can find on Google forks with this restriction removed. Of course don't go to me if it doesn't work as expected as I am not providing support for forks.

I gotcha, better safe than sorry sort of thing. I may have to give it a shot for TOTK because running it at 45 FPS mostly feels good, but I definitely get some frame pacing issues with the screen at 60 Hz.

Changing refresh rate makes experience miles better. Only con is that prerendered cutscenes are choppy.

With release of SaltyNX 1.0.0 now 32-bit games are also supported!
