5.   What is AMD FSR Redstone?

FSR Redstone is an upcoming suite of machine learning-powered graphics technologies from AMD, essentially a significant upgrade to the existing FSR framework, designed to enhance performance, image quality, and complex lighting in games. Its core purpose is to maintain high frame rates while enabling demanding lighting effects, such as path tracing, which simulates light’s physical behavior. As part of AMD’s open-source graphics technology, it aims to make these advanced effects widely accessible.

5.1  Core Features and Technology

• Neural Radiance Caching: This feature uses a neural network to learn and store how light bounces around a scene (indirect lighting). By caching this complex data, the system can predict and render the lighting much faster, drastically reducing the performance cost of high-quality ray tracing.
• ML Ray Regeneration: This is AMD’s answer to Nvidia’s Ray It employs a trained neural network to predict and reconstruct detailed pixels in a ray-traced scene, specifically targeting and filtering the grainy ‘noise’ that often plagues real-time ray and path tracing. The result is a much cleaner, more detailed image.
• Machine Learning Frame Generation: Replacing the older interpolation-based method of FSR 3, Redstone will feature a new ML-based model that uses temporal (time) and spatial (area) data to generate high-quality, intermediary frames. This significantly boosts perceived frame rates and overall motion clarity.

5.2  The Cross-Platform Revolution

One of Redstone’s most compelling aspects is its hardware-agnostic design. The neural rendering core is being built using a framework that converts its complex ML instructions into universal compute shaders. This means its core enhancement features can run on other GPU vendors’ hardware, not just AMD Radeon cards.

5.3  Impact on Consoles and Handhelds

• Nintendo Switch 2: Rumors suggest the next Nintendo console is built on Nvidia’s architecture. However, because FSR Redstone’s core technology is designed to be hardware-flexible, cross-platform games could potentially leverage AMD’s upscaling and ray tracing tools to achieve better performance on the device. This provides developers with an open-source, flexible option to manage performance, even on non-AMD
• Efficiency and Handheld Gaming: The efficiency gains from technologies like Neural Radiance Caching directly reduce the workload on the For handheld consoles, this is critical because a more efficient workload means less power consumption. This parallels the focus on power efficiency for devices like the PlayStation handheld or other portable gaming devices, improving handheld gaming performance and enabling longer playtime through battery-efficient gaming features.

Summary: AMD FSR Redstone uses AI to upscale and generate frames, competing directly with DLSS for sharper, faster gaming, with features like Neural Radiance Caching for efficient light handling.

Key Takeaways:

• Focuses on neural tech for ray tracing in PS6 and beyond, including ML Ray Regeneration for denoising.
• Could extend to desktop GPUs and consoles via AMD computing and graphics partnerships, with broad hardware compatibility.
• Aims to obsolete older methods with universal compression tweaks, expected late

5.4  How It Ties into Nintendo Switch 2 Rumors

Nintendo Switch 2 rumors, which started swirling in early 2025, heavily pointed to Nvidia hardware—specifically a custom Tegra chip based on Ada Lovelace tech. This made DLSS the expected go-to upscaler, with reports suggesting two versions: a standard one and a lighter model designed for resolutions beyond 1080p.

However, this is where AMD FSR Redstone enters the conversation. Some major cross-platform titles, like Elden Ring, already have existing FSR partnerships and might launch with it before adopting DLSS. We’ve heard that developers could ultimately choose between Nvidia DLSS and AMD FSR, with DLSS being optional. This technical flexibility is crucial for cross-platform games. For example, FSR 3’s frame generation could work seamlessly on the Switch 2, combining with ray tracing to improve visuals without overtaxing the hardware.

Since the Switch 2’s June 2025 launch (with backwards compatibility and titles like Metroid Prime 4 and Mario Kart World), the focus has shifted to post-launch support. With Redstone’s cross-vendor design, it is a viable option for multi-platform games ported to the system—such as potential Assassin’s Creed titles or Marvel Rivals—should developers prioritize FSR to achieve stable frame rates on the 8-inch screen.

The system’s rumored hardware—including 6 CPU cores, 9GB RAM available to developers, and DLSS presets—is constrained by the lack of VRR when docked, making efficiency from tools like FSR especially valuable for stable performance in portable mode. This upscaling flexibility means that anticipated titles, like the Cyberpunk 2077 preview on Switch 2, could use FSR Redstone to hit reliable frame rates if AMD’s updates apply.

Furthermore, the precedent is already set, with older Switch titles like Red Dead Redemption already utilizing FSR 2.2 for a visual boost. Now that the magnetic Joy-Cons have reportedly fixed drift issues, the conversation shifts to software like Redstone to enhance the graphical fidelity.

6.   DLSS vs. FSR on Switch 2: What the Rumors Say

A big question is “AMD Radiance Cores performance vs. DLSS.” While Radiance Cores are AMD’s ray tracing boost, Switch 2’s Nvidia base favors DLSS. Leaks indicate no DLSS in early footage, suggesting TAAU or FSR 1 as interim solutions. But with DLSS frame generation upgrades planned for 2026 games, FSR might fill gaps initially. Redstone’s ML Frame Generation could pair well here, depending on final Nintendo Switch 2 specs and GPU optimization.

6.1  Comparison Table: DLSS vs. AMD FSR Redstone for Handheld Gaming

 This could lead to more 120FPS titles if frame gen works well, especially in co-op games like the upcoming two-player survival title set for November 2025. We’ve added this because Switch 2’s launch window includes remakes like Dragon Quest 7, where upscaling choices could shine.

7.  Efficiency and Battery Life Implications

For PlayStation handheld features or Switch 2, GPU efficiency in future consoles is key. AMD FSR Redstone’s compression techniques, like delta color compression, could extend PlayStation handheld battery life by reducing load. Similarly, on Switch 2, combining AI upscaling technologies like FSR with DLSS might mean longer sessions without quality drops—think 4-6 hours on intensive titles—thanks to low-power GPU rendering optimizations.

We’ve expanded on this because handheld gaming demands balance—think shaders and textures rendering smoothly on the go, and Redstone’s low rendering cost helps there. With Switch 2’s lighter build (rumored under the Steam Deck’s weight), these tools could push it toward best handheld gaming console status.

8.   Broader Console Comparisons

Tied back to the Xbox partnership and Sony PS6, AMD FSR Redstone is teased for consoles like XSX, with FSR 4 elements. For Switch 2, it’s less central, but the tech’s evolution shows how graphics technology from Mark Cerny-inspired collabs influences everyone. Imagine path tracing in a Zelda remake—Redstone could make it viable on portable hardware, tying into PS6 GPU rumors and the anticipated FSR 4 release date on AMD Radeon RX 9000 series cards.

9.   Clearing Common Doubts

• The FSR Question: While DLSS is confirmed via the Tegra chip, the console’s cross- platform optimization may utilize the open-source AMD FSR for certain Switch 2 ports, offering developers another tool for maximizing performance and battery efficiency in a demanding hybrid console.

How is Ray Tracing Possible on the Nintendo Switch 2 Handheld Console?

The integration of advanced real-time lighting is a hallmark of the Switch 2’s next-gen graphics capabilities.

• DLSS-Powered RT: Ray tracing (RT) is achieved on the portable system through the custom Nvidia Tegra chip, which includes dedicated RT and Tensor Cores. The computational burden of generating lifelike lighting, shadows, and reflections is significantly offset by DLSS, which upscales the image from a lower base resolution, making ray tracing on handhelds both feasible and efficient.
• Future of Lighting with Redstone: For the ultimate realism, the more demanding path tracing in gaming is being made viable through technologies like FSR Redstone’s Neural Radiance Caching (NRC). NRC uses machine learning to streamline the rendering of complex light paths, boosting RT performance even on the compact, low-power portable
