AMD releases FidelityFX Super Resolution source code

By - | Views: 24,593

As promised when AMD revealed their answer to NVIDIA's DLSS, FidelityFX Super Resolution (FSR) is now officially open source and available under the MIT license.

What actually is it? AMD say "FSR uses super-optimized spatial upscaling technologies to help boost your framerates and deliver high-quality, high-resolution gaming experiences, without having to upgrade to a new graphics card.". It works on both AMD and NVIDIA GPUs too, so it's not locked to a vendor. The idea is to give "practical performance" for more costly rendering operations like Ray Tracing.

This open sourcing was announced today, along with information on both Unity and Unreal Engine will be supporting it for many more game developers to use. For Unity it's available in a special Unity 2021.2 HDRP release, while AMD provide special Unreal Engine patches for developers to add into UE to support it.

It already works just fine on Linux, and you can see it with the native title Dota 2 which already has it hooked up. You need to use Vulkan though, as AMD don't support it with OpenGL. FSR will work with both native Linux titles and Steam Play Proton too.

You can find the source on GitHub and see their blog post. They've also updated the dedicated GPUOpen website page with more info and new comparison shots.

Huh? The article mentions Vampire the Masquerade: Bloodhunt. Never heard of it. Is it a new game in development?

If you can't beat 'em [or afford to buy them], release the source code!

Side note; NieR: Automata was just updated with Fidelity FX support

We will definitely see FSR becoming better because of this.

I'm only interested in Vampire the Masquerade 2..

Valve should put this in gamescope as a scaling option.

is this the kind of thing that could be integrated into VKBasalt ? or does it require the game engine exclusively to run it.

Which doesn't look seem like is making good progress...

Quoting: WikipediaInitially scheduled for release in March 2020, the game was pushed back in late 2019 to an unspecified 2020 release date,[49] and further delayed in late 2020 to an unspecified 2021 release date.[51] In November 2020, Paradox CEO Ebba Ljungerud speculated that Bloodlines 2 would not be released in the first half of 2021. She explained the delay as caused by the staff changes, the 2020 COVID-19 pandemic, and a delay in receiving development kits for the PlayStation 5 and Xbox Series X/S consoles.[52] Along with the developer change in February 2021, the game was also delayed to past 2021
