FSR 4-Supported Cards, Games, How to Enable It and How It Compares to DLSS 4

FSR 4 solves a problem that most AMD RX 9000 series owners do not even know they have. Their GPU is capable of nearly double the FPS it is currently delivering. The only thing stopping it is one toggle in AMD Software that ships turned off by default.

Thirty seconds to enable. No new hardware. No new games. Just the FPS your GPU was always capable of.

This guide covers everything. What FSR 4 actually is. What changed in FSR 4.1 Redstone. Which cards support it. Which games support it right now. How to enable it step by step. And the honest comparison against DLSS 4 from real 2026 benchmarks.

Real FSR 4 Results From Real Gamers

An RX 9070 XT owner on Reddit posted: “Just enabled FSR 4 through Adrenalin and went from 54 FPS to 97 FPS at 4K in Cyberpunk 2077. The image is genuinely indistinguishable from native at Quality mode. Why is this not enabled by default?”

A Steam forum discussion about FSR 4 in Stellar Blade confirmed how the upgrade works: “There was an update note in the AMD drivers that games running FSR 3.1 will automatically run FSR 4. AMD FSR 4 features a new upgrade toggle in AMD Software that automatically upgrades supported games.”

Two different people. Two different games. Same conclusion — FSR 4 is a major free upgrade that most RX 9000 owners are not using yet.

What Is FSR 4?

FSR stands for FidelityFX Super Resolution. It is AMD’s upscaling technology — the same concept as NVIDIA’s DLSS. Instead of your GPU rendering every pixel at full native resolution, FSR renders the game at a lower resolution and uses AI to reconstruct a sharp, high-quality full-resolution image.

Think of it like this. At 4K, your GPU has to process 8.3 million pixels every single frame. With FSR 4 Quality mode, it renders at roughly 1440p internally — about 3.7 million pixels — and the AI reconstructs the rest. Your GPU does less than half the work. FPS nearly doubles.

FSR 4 launched on March 6, 2025 alongside AMD’s RX 9000 series RDNA 4 graphics cards. The biggest change from FSR 3 was switching from a traditional spatial upscaling algorithm to a machine learning based model — the same fundamental approach that makes DLSS so effective. This was a major architectural shift for AMD.

The key difference between FSR 4 and every previous FSR version: Earlier FSR versions (1, 2, 3) were spatial upscalers — they analyzed the current frame and used mathematical algorithms to reconstruct missing pixels. FSR 4 is a temporal machine learning model — it analyzes multiple frames over time and uses AI trained on thousands of games to intelligently reconstruct detail. The result is dramatically better image quality, especially in motion.

FSR 4 vs FSR 3 — What Actually Changed

The jump from FSR 3 to FSR 4 is the biggest quality improvement in the history of AMD upscaling. Digital Foundry’s testing confirmed this clearly.

Ghosting: FSR 3 had visible ghosting in particle effects explosions, smoke, fire, water splashes. FSR 4 has largely eliminated this. Testing in Horizon Forbidden West and Ratchet and Clank showed a marked improvement in particle effects that previously made FSR 3 look noticeably artificial.

Transparency: Glass, water, and transparent surfaces were a weak point in FSR 3. FSR 4 handles them significantly better, producing clearer water reflections and cleaner glass rendering.

Motion clarity: FSR 3 exhibited pixelization and anti-aliasing issues during fast movement. FSR 4 fixes most of these. Moving through a crowd or fast camera pans that looked rough in FSR 3 are substantially cleaner in FSR 4.

Texture detail: Overall texture sharpness is improved. Images from FSR 4 in testing appear sharper and cleaner overall compared to FSR 3.

The major trade-off: FSR 3 worked on almost any modern GPU including NVIDIA and Intel cards. FSR 4 officially only works on AMD Radeon RX 9000 series. This is AMD’s biggest competitive disadvantage versus DLSS which works across RTX 20, 30, 40, and 50 series.

FSR 4.1 Redstone — The 2026 Update

AMD announced FSR 4.1 Redstone in March 2026 with the driver release RN-RAD-WIN-26-3-1. This is an update to the FSR 4 framework that brings two meaningful improvements:

Improvement 1 — Expanded compatibility FSR 4.1 Redstone expands support to AMD Radeon RX 8000 series GPUs in addition to the RX 9000 series. RX 7000 series support is planned for July 2026. RDNA 2 based RX 6000 series support is planned for Q1 2027.

Improvement 2 — Artifacts reduced by 12 percent FSR 4 Redstone separates motion and luma/chroma sharpening, cutting artifacts by 12 percent compared to the original FSR 4. This particularly helps with spinning objects and geometry consistency in fast scenes.

New games confirmed with Redstone support:

• Crimson Desert
• DEATH STRANDING 2: ON THE BEACH

The FSR 4 Redstone naming explained: AMD has begun marketing FSR 4 under the “Redstone” brand name. All FSR 4 games technically qualify as Redstone-enabled. Think of Redstone as the umbrella brand for the FSR 4 generation going forward.

FSR 4 Supported Cards

This is the most important section for most readers. FSR 4 has very specific hardware requirements compared to FSR 3.

Full FSR 4 Support — RX 9000 Series (RDNA 4):

All NVIDIA GPUs — use DLSS instead. Our DLSS 4 guide covers everything for RTX card owners.

All Intel Arc GPUs — use XeSS 2 instead.

AMD RX 5000 series and older — no FSR 4 support planned.

FSR 4 Supported Games — Over 90 Titles

As of June 2026, FSR 4 is available in over 90 games. The number keeps growing with every AMD driver update. AMD’s AMD Software 25.9.1 driver brought FSR 4 support to 85 games in a single update by enabling FSR 4 Upgrade a feature that automatically applies FSR 4 to any DirectX 12 game that already supports FSR 3.1.

The complete and updated list is always available at AMD’s official FSR supported games page. Here are the most notable titles:

Important note about FSR 4 Upgrade:

Most of the 90 plus games do not have FSR 4 natively integrated yet. They use FSR 3.1. AMD’s FSR 4 Upgrade feature in Adrenalin Software automatically replaces the FSR 3.1 implementation with FSR 4 at the driver level. This works for DirectX 12 games that have integrated a signed FSR 3.1 DLL. Vulkan API games and games using non-standard FSR integration methods are not compatible with the FSR 4 Upgrade feature.

How to Enable FSR 4 Right Now

Enabling FSR 4 is a two-step process. You need to enable it in AMD Software first, then activate it in-game.

Step 1 — Update to the latest AMD Adrenalin driver

1. Open AMD Software: Adrenalin Edition
2. Go to Home tab
3. Click Check for Updates
4. Install the latest driver — you need at least version 25.3.1 for basic FSR 4 support, or 25.9.1 for 90 plus games

Alternatively download the latest driver directly from amd.com/en/support

Step 2 — Enable FSR 4 in AMD Software

1. Open AMD Software: Adrenalin Edition
2. Click the Gaming tab at the top
3. Go to Graphics sub-menu
4. Find FidelityFX Super Resolution 4 toggle
5. Turn it On

Once enabled, AMD Software will show a notification popup when you launch a supported game confirming FSR 4 is active.

Step 3 — Enable FSR in-game

1. Open your game
2. Go to Settings, Graphics, or Video
3. Find the upscaling or resolution scaling option
4. Select FSR and choose Quality mode

The FSR 4 Upgrade happens automatically at the driver level. You select FSR 3.1 in the game settings and AMD Software overrides it with FSR 4. You do not need to see an FSR 4 option in the game menu.

FSR 4 Quality modes:

• Quality — 67% of native resolution. Best image quality. Recommended for most players.
• Balanced — 58% of native. Good quality and strong FPS boost.
• Performance — 50% of native. Maximum FPS. Some visible quality reduction.
• Ultra Performance — 33% of native. Only for extreme FPS needs. Noticeable quality loss.

For most players gaming at 1440p or 4K: FSR Quality is the correct choice. You get 30 to 60 percent more FPS with image quality most players cannot distinguish from native at normal viewing distance.

FSR 4 vs DLSS 4 — The Honest Comparison

This is the question every AMD and NVIDIA owner wants answered. Here is what real 2026 benchmarks actually show.

The short version: DLSS 4 is sharper. FSR 4 is dramatically better than FSR 3 and competitive in many scenarios. Neither is bad. Which one you should use depends entirely on which GPU you own — not on image quality comparisons.

What TechSpot testing from February 2026 found:

FSR 4, like DLSS 4 and DLSS 4.5, does not suffer from TAA blur. The clarity of the image is similar both when stationary and in motion across all three technologies. However, DLSS 4.5 is noticeably sharper than FSR 4 in direct comparison. In general, FSR 4 produces a softer image than DLSS 4.5, so naturally it falls behind in sharpness. The FSR 4 image is certainly usable, but in many games the difference is noticeable during real-time gameplay on a 4K monitor.

What Digital Foundry testing confirmed:

FSR 4 goes toe-to-toe with the DLSS 4 CNN model and can even beat the latest DLSS Transformer model in some specific instances. This is a significant statement — it means FSR 4 is not universally inferior. In specific games and specific scenarios FSR 4 holds up very well.

The Reddit community debate:

A video review comparing FSR 4 Redstone and DLSS 4.5 claimed that DLSS 4.5 in Performance mode provides better image quality than FSR 4 in Quality mode. This sparked significant debate on r/Radeon — the post received 98 dislikes versus 17 likes — suggesting the community disputes the methodology or finds the comparison unfair. The honest answer is that both technologies have strengths and weaknesses depending on the game.

The honest bottom line: If you have an NVIDIA RTX card, use DLSS. It is better in most measurable ways. If you have an AMD RX 9000 series card, use FSR 4. It is dramatically better than FSR 3 and delivers genuinely excellent results even if it falls slightly behind DLSS in absolute sharpness. Never use FSR on an RTX card when DLSS is available.

Does FSR 4 Fix a GPU Bottleneck?

Yes — and it is the most effective free fix available for AMD GPU owners with a GPU bottleneck in 2026.

A GPU bottleneck occurs when your graphics card cannot produce frames fast enough to reach your target FPS. FSR 4 directly addresses this by reducing the work the GPU does per frame.

At 4K with FSR 4 Quality mode:

• Your GPU renders at approximately 1440p internally
• That is roughly 55 percent fewer pixels per frame
• FPS increases by 30 to 60 percent in most supported games
• AMD claims up to 4x FPS improvement in some 4K scenarios

If your GPU is at 95 to 100 percent usage and FPS is below your target, enabling FSR 4 is the first thing to try before considering any hardware upgrade. It is free, takes five minutes to enable, and in most supported games at 1440p and 4K the image quality difference from native is barely noticeable.

To confirm whether your system has a GPU bottleneck, a CPU bottleneck, or something else entirely, use our free PC Bottleneck Calculator it gives you the exact percentage for your specific CPU and GPU combination in 30 seconds.

Frequently Asked Questions

What is FSR 4 in simple words? FSR 4 is AMD’s AI upscaling technology. Your GPU renders the game at a lower resolution and FSR 4 uses machine learning to make the image look like it was rendered at full resolution. The result is significantly higher FPS with image quality most players cannot distinguish from native at Quality mode.

Which AMD cards support FSR 4? Currently only the Radeon RX 9000 series — RX 9070 XT, RX 9070, and RX 9060 XT. RX 8000 series support was added via the FSR 4.1 Redstone update in March 2026. RX 7000 series support is planned for July 2026. RX 6000 series support is planned for Q1 2027.

Does FSR 4 work on NVIDIA or Intel GPUs? No. FSR 4 is exclusive to AMD RDNA 4 architecture for now. NVIDIA RTX card owners should use DLSS instead — see our DLSS 4 guide. Intel Arc owners should use XeSS 2.

How do I enable FSR 4? Update to the latest AMD Adrenalin driver, go to Gaming, Graphics in AMD Software, enable the FidelityFX Super Resolution 4 toggle. Then in your game settings select FSR or FSR 3.1 and the driver will automatically upgrade it to FSR 4. Full step by step guide is in the How to Enable section above.

Is FSR 4 better than FSR 3? Yes, dramatically. FSR 4 eliminated the ghosting, motion artifacts, and texture blurriness that plagued FSR 3. The jump from FSR 3 to FSR 4 is the biggest quality improvement in AMD upscaling history. Digital Foundry confirmed FSR 4 can go toe-to-toe with DLSS 4 in many scenarios something FSR 3 could never claim.

Is FSR 4 better than DLSS 4? DLSS 4 is sharper and supports more games across more GPU generations. FSR 4 is dramatically better than FSR 3 and competitive in many real-world scenarios. The correct answer is: use whatever matches your GPU. DLSS if you have NVIDIA RTX. FSR 4 if you have AMD RX 9000.

What is FSR 4 Redstone? FSR 4.1 Redstone is AMD’s March 2026 update to FSR 4. It expands compatibility to RX 8000 series, reduces artifacts by 12 percent, adds support for new games like Death Stranding 2 and Crimson Desert, and introduces the Redstone marketing name for the FSR 4 generation going forward.

Does FSR 4 work on all games? FSR 4 works on DirectX 12 games that support FSR 3.1 with a signed DLL. As of June 2026 that is over 90 games. Vulkan API games and games using non-standard FSR integration are not compatible with the FSR 4 Upgrade feature. The full list is at gpuopen.com.

One Last Thing

FSR 4 is the best reason to own an AMD RX 9000 series GPU in 2026. It is not just competitive with DLSS — it is genuinely excellent. The jump from FSR 3 is massive. Games that looked rough and artifacted with FSR 3 now look clean and detailed with FSR 4.

If you have an RX 9070, RX 9070 XT, or RX 9060 XT and you have not enabled FSR 4 in AMD Software yet, open Adrenalin right now and turn it on. Your FPS at 4K will nearly double and you will wonder why you ever played without it.

And once you have enabled FSR 4, use our free PC Bottleneck Calculator to check whether your CPU and GPU are properly matched. Sometimes enabling FSR 4 reduces GPU bottleneck enough that a CPU bottleneck becomes visible that was previously hidden. The calculator tells you exactly what is limiting your system in 30 seconds.
