AMD FSR SDK 2.4 is now officially out bringing the newer FSR Upscaling 4.1.2 for older Radeon GPUs and Ryzen APUs, along with Vulkan support for newer FSR. They really dragged their heels on hooking up Vulkan support, glad to see it’s finally here.

In the announcement they said:

AMD FSR Upscaling 4.1.2 keeps the models already shipping on AMD Radeon™ RX 9000 Series (AMD RDNA™ 4 architecture, full FP8) and Radeon RX 7000 Series discrete (RDNA 3 architecture, full INT8) GPUs, and adds the full INT8 model on:

• AMD Radeon™ RX 6000 Series discrete GPUs (AMD RDNA™ 2 architecture).
• AMD Ryzen™ AI Max 300 Series processors (“Strix Halo” with AMD RDNA™ 3.5 architecture Radeon™ 8000S Series graphics).
• AMD Ryzen™ AI Max 400 Series processors (“Gorgon Halo” with AMD RDNA™ 3.5 architecture Radeon™ 8000S Series graphics).

A second, highly optimized INT8 model brings ML-based FSR Upscaling to more constrained integrated graphics. That model is less than half the size of the full INT8 model and is purpose-built for this class of hardware:

• AMD Ryzen™ AI 9 300 Series processors (“Strix Point” with AMD RDNA™ 3.5 architecture Radeon™ 800M Series graphics).
• AMD Ryzen™ AI 9 400 Series processors (“Gorgon Point” with AMD RDNA™ 3.5 architecture Radeon™ 800M Series graphics).
• AMD Ryzen™ AI Z2 Extreme processor (“Strix Point” with AMD RDNA™ 3.5 architecture graphics).
• AMD Ryzen™ Z2 Extreme processor (“Strix Point” with AMD RDNA™ 3.5 architecture graphics).
• AMD Ryzen™ Z2 A processor (with AMD RDNA™ 2 architecture graphics).

Model selection is automatic and based on the target hardware. More capable integrated AMD Radeon 8000S Series GPUs in the Ryzen AI Max 300 and 400 Series run the full INT8 model. The other AMD Ryzen processors listed above run the lightweight INT8 model, tuned for a balance of image reconstruction quality and performance on laptops and handhelds. Results vary by game, resolution, quality mode, and hardware. AMD has focused on delivering a stable, broadly useful solution across all supported platforms.

As for the Vulkan support, here’s what they said:

The AMD FSR™ SDK 2.4 is the first FSR “Redstone” release with Vulkan® support at feature parity with DirectX® 12 for the upscaling and frame generation effects:

• AMD FSR™ Upscaling 4.1.2.
• AMD FidelityFX™ Super Resolution 3.1.6.
• AMD FSR™ Frame Generation 4.0.2.
• AMD FidelityFX™ Super Resolution Frame Generation 3.1.6.
• AMD FSR™ Frame Generation (Swapchain) 4.0.0.
• AMD FidelityFX™ Super Resolution Frame Generation (Swapchain) 3.1.7.

Vulkan support is provided by the FSR SDK 2.4 DLLs, so it requires integrating this SDK into your game. Existing Vulkan games with AMD FidelityFX Super Resolution 3.1 upscaling or frame generation are not automatically upgraded to ML-based FSR Upscaling or FSR Frame Generation through the driver, as those upgrades apply to DirectX 12 games only. Vulkan games that integrate AMD FSR Upscaling 4.1.2, FSR Frame Generation 4.0.2, or FSR Frame Generation (Swapchain) 4.0.0 or later are eligible for automatic upgrades to future versions through AMD Software: Adrenalin Edition™.

On Vulkan, the frame generation swapchain replaces the application’s VkSwapchainKHR and returns replacement function pointers for swapchain creation, image acquire, and present.

Samples in this SDK run on Vulkan 1.2. AMD FSR Ray Regeneration and AMD FSR Radiance Caching remain DirectX 12 effects in this release.

There’s much more information about the ins and outs in the original announcement.
