Are you using the Direct3D patch for the game?

The original Windows version doesn't have a Direct3D Patch. You're confusing it with "Daytona USA Deluxe", which is a port of the reworked "Daytona USA: Championship Circuit Edition" for the Sega Saturn. This game has better graphics, runs at 30fps and has a Direct3D patch.

The original Daytona USA for PC was a very rough port. They could've made it so much better.
This option is never saved and I don't see much difference, maybe it does make a difference on slower machines.

Cybertroopers: Virtual On have the same exact setting. Here the option is more noticeable as it is a fighting game (with robots 😁 ). It cuts down the amount of frames in the animation, making the game run better on slower computers. It also seems to limit the FPS in the game to 20-21, while the SMOOTH option sets the limit at 30FPS.

Sonic 3D Blast even is similar, though smooth is 60fps for that. Defaults to 30.

Is that the one that required the NV1, since it used quadratic polys, instead of the standard "triangular" polys? I had a buddy who owned one of those. Worked fine for Saturn ports (even had a port on the back for a saturn controller), but sucked hard with any game that used standard polys.

No, Daytona USA doesn't have support for the Nvidia NV1 (although it's possible that it was planned at some point).
However, some other Saturn ports do have support for the NV1.

I never really knew what that option does, but it does seem to make it smoother. Key controls aren't saved in the menu either. If you hunt around for the .ini file related to the game, you can set the menu to allow a mouse pointer, or keep it on all the time, I seem to remember.

So I was right, the setting does change the game's framerate. For some reason it doesn't appear to work in Daytona USA, and the game is stuck in the lower quality setting. Since it's impossible to change this setting via the UI, I tried to fiddle with the DAYTONA.INI file and to guess the setting's name, but this didn't work either.

That's strange - I set my key controls via the menu and they were saved.
And no, it isn't smoother. I thought so, too, but it's the same choppy 20fps in both settings. And this is the only setting in the UI that resets itself to default everytime, so it doesn't get saved.

One more funny thing about Daytona USA; if you read the help file (I think) there's quotes from the developers, one says "this is my first PC game!" or something like that!

Why am I not surprised? 🤣
