UpscalerSwitcher Plugin for Unreal Engine

The UpscalerSwitcher plugin provides dynamic control over upscaling methods in Unreal Engine, allowing seamless switching between technologies like FSR (FidelityFX Super Resolution) and DLSS (Deep Learning Super Sampling). It also includes a custom game user settings class to save and load your preferred upscaling method and quality settings for future sessions.

Key Features

Dynamic Upscaling Control: Easily enable or disable FSR and DLSS upscaling, giving users the flexibility to switch between different upscaling techniques based on their preferences or hardware capabilities.
Runtime Switching: Switch between upscaling methods such as FSR and DLSS during gameplay without restarting the game.
Quality Adjustment: Adjust screen percentage and quality settings for each upscaling method
Persistent Settings: Automatically save the selected upscaling method and quality preferences to a configuration file, ensuring that your settings are preserved between game sessions.

Important Notes

This plugin does not include the DLSS or FSR modules by default. To use the UpscalerSwitcher plugin, you need to download and install the official DLSS and FSR plugins into your Unreal Engine project. These plugins are available from their respective providers (NVIDIA for DLSS and AMD for FSR).
Saving Feature: To enable the saving of the upscaling method and quality settings, you must use or inherit from the provided UpscalerGameUserSettings class. This ensures that the settings are saved to a configuration file and persist across game sessions.

Will it be available in 5.6?

Friqhers · June 23, 2025, 4:14pm

It should work fine with 5.6, but I’ll make sure to test it and update the plugin when I have some free time.

HiImGh0st · June 25, 2025, 10:20am

Hi. I have DLSS and FSR added to my project in 5.5. I’m using your plugin. I keep getting this message repeatedly during gameplay:

LogDLSS: Error: Another plugin already set FSceneViewFamily::SetTemporalUpscalerInterface()

Can you help me?

Friqhers · June 25, 2025, 3:51pm

Hi! Of course, I’d be happy to help you.
Can you please send me the full log file from when this error occurs? Also, it would be helpful if you can show me how you’re applying the upscaler in your code.

HiImGh0st · June 26, 2025, 10:43am

I tried to send all the details to this email address: support@pengurugames.com

Unfortunately, I get a message saying that the mailbox is full.

I’m not sure why you’re encountering that mailing error it seems to be working fine on my end.

When can we expect the 5.7 UpscalerSwitcher release?

Cordevil · January 9, 2026, 12:57am

Can you update this for 5.7? Its a great easy to use product.

Cordevil · January 16, 2026, 10:28pm

What about 5.7? Its the last plugin I need to upgrade to 5.7

I get this error [2026.08.17-21.10.05:397][ 58]LogDLSS: Error: Another plugin already set FSceneViewFamily::SetTemporalUpscalerInterface()

Friqhers · August 18, 2026, 9:46am

Hi! Thanks for reporting — this is a bug on my side and it’s now fixed.

The AMD FSR plugin renamed its console variables in 4.x, so UpscalerSwitcher could no longer turn FSR off when switching to DLSS, and both plugins fought over the upscaler slot. The new version handles either naming.

I’ve uploaded the fix to Fab, should be live in a few days. If you don’t want to wait, hop on the Discord and I’ll send you the build now.

Quick workaround meanwhile: uncheck Project Settings → FSR Upscaling → Enabled while using DLSS.

jaarekt · August 18, 2026, 9:52am

Hey thank you for this, I really need it for my project its in UE5.7 version, btw your discord invite expired.

Merhaba,

Projem UE 5.3 - Upscaler plugininizi denedim.
FSR fg hiçbir şekilde çalışmıyor. Nvidia FG plugini açıkken her türlü fsr fg’nin önüne geçiyor ve swapchain yapamıyor. Birçok deneme yaptım ama olmadı.

Fsr frame generation tickini kapatmayı denedim olmadı. Game instance event init kısmında da get upscaler game settings>apply settings yapıyorum.

Kısaca nvidia fg plugini açıkken fsr fg asla çalışmıyor.

FSR 3.1
Dlss 8.3

Friqhers · August 24, 2026, 10:20am

Merhaba,

Sorunu yaşadığınız anda oluşan logları paylaşabilir misiniz?

Bir de GameInstance -> Event Init yerine PostEngineInit kısmında Get Upscaler Game Settings -> Apply Settings yapmanız gerekiyor. Dokümantasyonun en sonunda bunun örneği bulunuyor:

C++ tarafına dokunmak istemiyorsanız, Default GameInstance Class olarak hazır UpscalerGameInstance sınıfını da kullanabilirsiniz.

Bu şekilde de sorun devam ederse logları gönderirseniz inceleyebilirim. Ayrıca Discord sunucusuna katılırsanız daha detaylı yardımcı olabilirim.

Hi there,

Having an issue just with FSR frame gen. Everything else appears to be working as expected including FSR super resolution. Getting this crash whenever FSR Frame Gen is enabled:

Any idea why this is the case?

Also the discord link both on the product page on Fab and here in the forum thread has expired again.

Thanks!

EDIT:

Attempted this with runtime switching disabled and getting the same error when I restart with the FSR FG enabled. Everything else, DLSS-SR, DLSS-FG, FSR-SR working perfectly.
