AMD FSR 4.1 on Radeon RX 6000: Which GPUs Get It, How to Enable

AMD has switched on its machine-learning upscaler, FSR Upscaling 4.1, for every Radeon RX 6000 desktop card, years ahead of the early-2027 date it had promised. If you own an RX 6400 up to an RX 6950 XT, you can turn it on today with Adrenalin 26.10.1. Here is exactly which hardware gets it, how to enable it, and what it costs in performance.

Quick summary

• FSR 4.1 is live for Radeon RX 6000 (RDNA 2) from the 26.10.1 driver, released October 20, 2026.
• Also covered: Ryzen AI Max 300/400 and Ryzen AI 9 300/400 laptops, plus Ryzen Z2 handhelds via maker drivers.
• Xbox Series X|S support is listed as "coming soon" with no date.
• Tom's Hardware measured roughly a 13% fps cost on an RX 6900 XT versus the same preset with older upscaling.
• It is upscaling only: no ML frame generation or ray regeneration on RX 6000.

Which Radeon RX 6000 cards support FSR 4.1?

AMD's release notes list the RX 6900, 6800, 6700, 6600, 6500 and 6400 series, and outlets that checked the driver report the range runs from the RX 6400 to the RX 6950 XT. RX 7000 cards already had FSR 4.1 since mid-2026, and the RX 9000 series had FSR 4 from launch.

How do I enable FSR 4.1 on an RX 6000 card?

Install AMD Software: Adrenalin Edition 26.10.1 (driver 26.20.15.07) from AMD's site or the Adrenalin app, then open the Graphics tab and switch on the FSR 4 upscaling option. HotHardware notes you can confirm it is active in the Radeon overlay (Alt+Z by default). Officially it works in DirectX 12 games, and titles that hard-code FSR rather than using an external library may not be overridable.

How much performance does FSR 4.1 cost on RDNA 2?

The ML model is heavier than the old FSR 2/3 math, so expect a small hit. Tom's Hardware's quick test with Cyberpunk 2077 at 4K in Balanced mode on an RX 6900 XT put the cost at about 13%. HotHardware's RX 6800 XT testing found FSR 2.1 was always faster at the same input resolution, but FSR 4.1 Performance still beat FSR 2.1 Quality in Cyberpunk while looking clearer, and it said the hit was far smaller than the up-to-40% seen with leaked-model mods like Optiscaler.

In Hogwarts Legacy at 4K, FSR 4.1 Quality gave about a 33% average fps boost over native on the RX 6800 XT (66.3 fps). In Gears of War: E-Day at 4K, the card averaged 52.66 fps on mixed High/Ultra settings.

Is FSR 4.1 better than FSR 2 and FSR 3 on older Radeon cards?

Yes, and by a wide margin in image quality. HotHardware called the difference "night and day" in Cyberpunk 2077: the older upscaler produced ghosting on distant moving objects and blue artifacts on signs, which FSR 4.1 avoided even at a lower internal resolution. Our takeaway: use Quality mode when you can spare the frames, since Performance mode can lose fine details and soften foliage.

What is still missing?

• Only upscaling comes to RX 6000 and RX 7000; the wider FSR "Redstone" feature set stays on RX 9000.
• Vulkan support for FSR 4.1 is promised "at some point", with no date.
• Xbox consoles and Z2 handhelds depend on Microsoft and device makers shipping updates.
• Ray tracing remains weak on RDNA 2, so FSR does not fix heavy RT games.

Should RX 6000 owners upgrade their GPU now?

Probably not for this reason alone. GPU prices have been climbing (see our report on GPU prices rising 35% in three months), and FSR 4.1 gives older Radeon cards a real quality lift for free. Check whether your games run well first with our PC checker, and watch deals before spending.
