AMD announced FSR Upscaling 4.1 support for Radeon RX 6000 through Adrenalin Edition 26.10.1 on October 20, 2026. Tests on an RX 6800 XT and a separate RX 6950 XT report clearer images than older FSR versions in their comparisons, alongside frame-rate costs that vary by game and settings. Those results describe specific test setups, not every RX 6000 card.
What the RX 6000 tests cover
AMD says it optimized an INT8 model originally created for RX 7000 to enable FSR Upscaling 4.1 on RX 6000. That describes the implementation AMD announced; it does not predict a particular card’s frame rate.
HotHardware tested a reference Radeon RX 6800 XT with Adrenalin Edition 26.10.1 in Cyberpunk 2077, Hogwarts Legacy, Crimson Desert and Gears of War E-Day. A separate account from Club386 summarizes Hardware Unboxed testing a Radeon RX 6950 XT at 4K in Mafia: The Old Country, Horizon Zero Dawn Remastered and Cyberpunk 2077.
A gameplay video compares native rendering and FSR modes on an ASUS Dual Radeon RX 6600 8GB, with performance overlays across several games.
Hogwarts Legacy frame rates on the RX 6800 XT
HotHardware’s Hogwarts Legacy chart reports these results at 3840×2160 with Ultra settings. “1% low” is a frame-rate measure that captures performance during the slowest-running frames; higher values are generally smoother.
| Mode | Average FPS | 1% low FPS |
| FSR 2.1 Performance | 104.4 | 73.5 |
| FSR 2.1 Quality | 79.2 | 58.8 |
| FSR 4.1 Performance | 78.4 | 58.0 |
| FSR 4.1 Quality | 66.3 | 52.1 |
| Native 4K / TAA High | 49.7 | 37.6 |
In this test, FSR 4.1 Quality averaged about 33% more frames per second than native 4K, but both FSR 2.1 modes posted higher averages than either FSR 4.1 mode. The result is a choice between the image quality of a particular upscaling mode and the frame rate it delivers, not a blanket speed gain from moving to FSR 4.1.
Image quality and speed depend on the game
In Cyberpunk 2077, HotHardware found FSR 2.1 faster than FSR 4.1 at the same input resolution. The tester judged FSR 4.1’s image clearer, with less observed ghosting and artifacting, though aliasing remained on difficult reflective surfaces. The comparisons covered 4K Ultra without ray tracing and a separate 2560×1440 setup with customized RT High settings.
For Crimson Desert, HotHardware preferred FSR 4.1 Quality over Performance for its balance of image quality and speed. In that test, lowering render resolution changed lighting and shading. The game did not offer an FSR 2 or FSR 3 comparison in the test, so the result speaks to the two FSR 4.1 modes and native antialiasing there.
In Gears of War E-Day, HotHardware recorded 52.66 average FPS at 4K output with a mix of High and Ultra Auto settings. Changing the scaling preset appeared to have little effect; the tester suggested dynamic resolution scaling may have been active.
The separate RX 6950 XT results add another reference point, not a family-wide benchmark. Club386’s account of Hardware Unboxed’s 4K tests reports FSR 4.1 running 13% to 34% slower than FSR 3.1 across the three games. It also describes FSR 4.1 image quality on the RX 6950 XT as practically identical to the RX 7900 XTX’s INT8 output and RX 9070 XT’s FP8 output, and markedly better than FSR 3.1. Settings were reduced on the RX 6950 XT to help maintain base-frame-rate parity.
Where to enable FSR and what the test says about game support
HotHardware locates the AMD FSR Upscaling control in Adrenalin’s Graphics settings and says Radeon Overlay can indicate whether FSR is active. Its test used Adrenalin Edition 26.10.1.
HotHardware describes the official driver support path as limited to DirectX 12 games. Games that integrate FSR directly into their code may not be overridden through the external-library path. The practical check is whether the FSR Upscaling control is available for the game and whether Radeon Overlay indicates that FSR is active.
