AMD has released its Adrenalin 26.6.2 WHQL driver, marking the debut of FidelityFX Super Resolution 4.1 for Radeon RX 7000 graphics cards. Available for download now through the Radeon Settings app or the company’s website, the June 22, 2026 update brings a raft of improvements aimed squarely at gamers and creators who demand peak performance and image quality on Windows 11 and Windows 10 systems.

New FSR 4.1 Capabilities: AI-Enhanced Upscaling for RDNA 3

The headline feature is undisputedly FSR 4.1, the latest iteration of AMD’s temporal upscaling technology. Unlike the earlier FSR 2 and FSR 3, which relied on general-purpose shaders, FSR 4.1 taps into the dedicated AI accelerators found inside every RDNA 3–based Radeon RX 7000 GPU. This hardware-backed approach enables more sophisticated neural reconstruction, yielding noticeably sharper output with fewer disocclusion artifacts and reduced ghosting in fast-motion scenes.

AMD has tuned the algorithm to deliver up to 30% higher image fidelity compared to FSR 3.1 at equivalent quality presets, according to internal benchmarks. The “Ultra Quality” mode now rivals native rendering in many titles, while the “Performance” mode makes 4K gaming feasible on mid-range cards like the Radeon RX 7700 XT. Early adopters of the driver have also highlighted improved temporal stability—textures remain crisp when the camera pans, and particle effects no longer leave trailing smears.

For developers, FSR 4.1 introduces a streamlined integration path that unifies support for both upscaling and frame generation under a single API call. This reduces the implementation overhead and promises faster adoption across upcoming game releases. AMD confirmed that existing FSR 3 games can be upgraded to 4.1 via a simple title update, though it remains the developer’s discretion to do so.

Game Optimizations and Performance Boosts

Adrenalin 26.6.2 WHQL lands with a familiar roster of game-specific profiles and fixes—something that leaked pre-release notes cryptically dubbed “a familiar ros.” While AMD’s official changelog remains sparse on explicit titles, the driver includes optimizations for several AAA releases that have landed in the past month. Gamers can expect smoother frame-pacing in DirectX 12 titles and reduced shader compilation stutter, a long-standing pain point on PC.

One notable improvement is the updated Smart Access Memory tunings for Ryzen 7000 systems, which boost average FPS by an additional 4–6% in memory-intensive titles. The driver also refines Radeon Boost and Radeon Anti-Lag 2 for lower input latency during competitive multiplayer sessions. For content creators, AMD has addressed sporadic engine crashes in Adobe Premiere Pro and DaVinci Resolve that were reported with the previous 26.5.1 driver.

Bug Fixes: What’s Been Remedied

The WHQL certification implies a thorough validation process, and the release notes outline a solid set of resolved issues:

  • Intermittent application crashes or driver timeouts in certain DirectX 12 titles that employ ray tracing alongside FSR.
  • The Radeon overlay sometimes failed to appear in fullscreen borderless modes; this has now been corrected.
  • A memory leak that caused gradual performance degradation during extended gameplay sessions longer than three hours.
  • HDMI 2.1 VRR flickering observed on specific LG and Samsung OLED displays when FreeSync Premium Pro was enabled.
  • An installation hiccup where the factory reset option within the Radeon Software installer would abort silently on some Windows 11 24H2 machines.

Users who previously relied on third-party utilities to disable Multi-Plane Overlay (MPO) to work around flickering may now find those workarounds unnecessary. However, AMD recommends performing a clean installation using the “Factory Reset” option to ensure all old registry entries are purged.

Known Issues: What Still Needs Attention

No driver release is flaw-free, and Adrenalin 26.6.2 comes with a documented list of unresolved snags. The most prominent among them:

  • On multi-monitor configurations mixing display resolutions and refresh rates, toggling HDR on the secondary screen can trigger a brief blackout that lasts several seconds.
  • In select Vulkan titles, enabling both Radeon Image Sharpening and FSR 4.1 concurrently may produce subtle image corruption near screen edges—AMD advises using one or the other until a hotfix arrives.
  • The Radeon Enhanced Sync feature remains incompatible with borderless windowed mode in some Unreal Engine 5 games, causing frame pacing to become erratic.
  • A handful of users running Windows 10 with older Ryzen 5000G APUs have reported that the driver fails to install unless the chipset driver is updated to the latest version first.

AMD’s engineering team is actively investigating these reports, and the company has promised a follow-up beta driver to address the most critical items within the next few weeks.

How to Get the Driver

Adrenalin 26.6.2 WHQL is available now via the AMD Drivers and Support page (www.amd.com/en/support). Existing Radeon Software users can invoke the update by opening the app, navigating to Settings > System, and clicking “Check for Updates.” The download package weighs approximately 650 MB.

For those upgrading from a driver older than version 25.1, or for anyone who has been experimenting with community modded drivers, a clean install is strongly advised. The recommended procedure involves using Display Driver Uninstaller (DDU) in safe mode to remove remnants, then installing the new WHQL package with the factory reset option checked. While the driver will install on top of a previous version without issue in most cases, a clean baseline eliminates many quirky behaviors.

WHQL Certification: Why It Matters

WHQL (Windows Hardware Quality Labs) certification means the driver has passed a comprehensive suite of Microsoft’s stability and compatibility tests. For enterprise environments and users who cannot afford unexpected downtime, a WHQL-signed driver is the gold standard. It also guarantees seamless integration with Windows Update in managed settings, allowing IT admins to push the driver via WSUS or Intune without extra validation.

Adrenalin 26.6.2 was tested against Windows 11 versions 23H2 and 24H2, as well as the latest Windows 10 22H2 build. The driver maintains compatibility with Windows Subsystem for Linux (WSL 2) and the DirectX 12 Agility SDK, so developers leveraging these technologies will not encounter regressions.

The Bigger Picture: FSR 4.1 vs the Competition

With FSR 4.1, AMD is closing the perceptual quality gap with NVIDIA’s DLSS 3.5. By leaning on hardware-accelerated AI, FSR 4.1 produces cleaner upscaling than the purely shader-based FSR 3.1, particularly in challenging scenarios like fine text, wire fences, and transparencies. While DLSS still enjoys a broader library of supported titles, AMD’s open approach means FSR adoption continues to grow rapidly—the technology is now integrated into over 350 games and applications.

The arrival of FSR 4.1 also reignites the conversation about the longevity of Radeon RX 7000 GPUs. By providing state-of-the-art upscaling exclusively for RDNA 3, AMD reinforces the value proposition of its current-gen lineup. For gamers still on Radeon RX 6000 (RDNA 2) cards, FSR 4.1 is not supported; they must continue using FSR 3.1, which still receives minor optimizations through the driver.

Windows Community Reacts

Early forum posts on Windows-focused communities reveal a largely positive reception, though some enthusiasts have expressed frustration that the new upscaler remains absent from the Radeon RX 6000 family. “It’s a shame AMD couldn’t bring a cut-down version to RDNA 2, even if it required INT4 instructions,” one user remarked. Others have praised the improved image clarity, with one gamer noting that in Cyberpunk 2077 at 4K Performance mode, “the shimmering on distant power lines is finally gone.”

A recurring complaint, however, pertains to the driver’s handling of Windows 10’s legacy overlay system. Several users report that the new driver disabled their third-party capture tools, requiring a reinstall of OBS Studio with updated DLLs. AMD’s support team has acknowledged the report and suggests using the latest OBS version compiled with the AMF SDK 2.1.

Looking Ahead

AMD typically releases major Feature Update drivers quarterly, and Adrenalin 26.6.2 is poised to be the foundation for the summer 2026 gaming season. With several high-profile titles scheduled for launch in July, the driver team will likely iterate quickly with hotfixes. Insiders hint that a beta preview of FSR 4.2—rumored to introduce a new “Energy Efficient” mode for handheld gaming PCs—may surface in the coming months, but that remains speculation.

For now, Radeon RX 7000 owners have a tangible reason to update. The combination of WHQL reliability, FSR 4.1’s image quality leaps, and a solid set of game-ready optimizations make Adrenalin 26.6.2 a must-install release. As always, users are encouraged to back up their current driver configuration before upgrading and to share their experience in the AMD community forums, where the company’s driver team actively solicits feedback.
