AMD Releases FidelityFX SDK v1.1 to GPUOpen, Includes FSR 3.1 Source Code
AMD today released the FidelityFX SDK 1.1 to the public through its GPUOpen initiative. This update includes the source code to FSR 3.1, which should make it easier for game developers to understand the technology, and integrate it with their games. FSR 3.1 requires an AMD Radeon RX 5000 series (or later) GPU, or an NVIDIA GeForce RTX 20-series (or later) GPU, although the company recommends at least an RX 6000 series or RTX 30-series GPU, regardless of model. You get the full upscaling and frame-generation capabilities of FSR 3.1 on all supported GPUs, across AMD and NVIDIA, which is the main pull for the tech, as the rival DLSS 3 Frame Generation technology only works on RTX 40-series (or later) GPUs.
AMD FSR 3.1 builds on top of FSR 3 by introducing updates to the upscaler. If you recall, the star attraction with FSR 3 has been frame-generation, but the underlying upscaling tech had been carried over from FSR 2.2. FSR 3.1 introduces some much-needed updates to the quality of upscaling, and introduces new upscaler quality presets, including a native AA mode analogous to NVIDIA's DLAA. These increases in upscaler quality lets you trade in quality for performance better. You can find all the resources you need on FSR 3.1 here.

Hopefully this will push Nvidia to launching their own FG tech outside of current hardware limitations.
I've been very impressed with lossless scaling FG mind you, works fantastic with content that is hard limited at 60 fps or less, like 30/60 FPS switch games on Yuzu doubled to 60/120 (I own every game I play on Yuzu), and 24fps video content doubled to 48. Very effective in removing judder from 24/30 fps content at the expense of some artefacts. Personally, I think this is unrealistic, I'd put money on it staying a 40 series+ feature. Especially since AMD have decoupled FG from their resolution scaling, and Lossless scaling exists, if I were Nvidia I just don't see the incentive to release a worse version for older hardware, those versions already exist and they can distance themselves from the results being demonstrably worse.
So FSR 3.1 is a slightly downgraded DLSS 3.7.20 but FSR 3.1 is close to the performance and works cross platform where DLSS 3.7.20 is on RTX only.
I'm glad to see competition!
DLSS 3.7.20 came with July GeForce 560.70 Driver.
560.70 Driver should of launched with my RTX 4080 Super 16GB card back in February. Lots of big gains in 6 months in performance.
FSR 2.2 to FSR 3.1
DLSS 3.5.10 to DLSS 3.7.20
So close in performance it's a win-win for us consumers with huge performance gains in the last 6 months with 7900 Series & SUPER Series very interesting to see our investments performance blossom.
Cheers
