Checklist

I have searched for a similar issue in this repository and did not find one.
I am using an official build obtained from releases or updated one of those builds using its in-app updater.

Describe the Bug

I enabled FSR in the game-specific settings and also activated the 1440p patch.
In-game, I can clearly see the difference, so FSR is definitely working.
However, in the Debug (Ctrl + F10) overlay, it still shows “Off” for FSR status — even though under Display > FSR it’s shown as enabled.

I know this might seem related to the patch, but since the emulator shows two conflicting FSR states, I believe this could be an emulator-side bug rather than a patch issue.

As you can see, it is "Off" in the summary view, but it appears to be on in the "Display > FSR" tab:

Log: I have to enable 1440P patch, otherwise you won't see the error.

CUSA03173.log

Reproduction Steps

Probably an if–else error.

Expected Behavior

The same thing should be written on both sides, because the user usually reads the summary and doesn't look at the menus.
This inconsistency can cause confusion.

Not a bug, FSR is indeed enabled but there's nothing to "upscale" since the game resolution is the same as the output resolution, to properly use FSR run the game at 1080p and you'll see it's enabled.

This is correct, and I understood it. However, it appears enabled in the menu, which can be confusing.

Does RCAS work like this? I mean, if I only want sharpening but FSR is disabled?

That's the intended behavior, FSR is on in the settings because you want it to be on but has no effects since the condition for it aren't met, the emulator can't turn off the option because the conditions aren't met, I don't have shadPS4 installed currently but I believe the description of FSR should explain all that if you hover over the setting in the GUI.

I've been told that "RCAS has no effect if FSR is off " so I don't think you can have that.

There’s no description written for FSR in the QT, I just checked.

I wish we could enable sharpening even when FSR isn’t active or running, but I’m not sure if that’s technically tied to FSR itself.

I guess the image can’t be rendered at a lower resolution since FSR isn’t implemented at the engine level, so it can’t properly perform the upscaling to 1440p.

Then that's my bad, someone should probably add one since it's a bit confusing without explanation, I believe a lot of these options in the GUI don't actually have a description so it should really be taken care of.

Alright, understood, thanks again for the clarification!
Do you want me to keep this issue open, or should I close it?

I'm just a random person, I'm not affiliated with shadPS4 at all so it's up to you but since it's not really a bug I think it's best if you close it, if you really feel like it you could open a feature request on the QtLauncher repository about wanting to have a description for FSR (or for all the settings available in the GUI), but if you don't want to that's fine, I can probably open one in the next few days.

Guess I’ll have to start learning C++ soon if I want to help out with the emulator myself 😄
