Intel Arc GPU Graphics Drivers 101.6449 WHQL Released

Intel has released a new WHQL graphics driver package, version 101.6449, focused on providing day-one support for their latest Core processors, codenamed Twin Lake, Raptor Lake-H Refresh, and Raptor Lake-U Refresh. This includes the new Intel Core Ultra Series 1 and Series 2 with built-in Arc GPUs. The driver also addresses a number of issues across various Intel Arc graphics products, including crashes and performance problems in popular games like Skull and Bones, Tom Clancy’s Rainbow Six Siege, and Call of Duty titles.

Despite these fixes, Intel acknowledges several known issues persisting in this release. These range from graphical corruptions in games like F1 24 when using XeSS FG, to application crashes in professional software such as Dassault Systèmes CATIA and Topaz Labs Photo AI. Users of Intel Arc A-Series Graphics Products and Intel Core Ultra Series are also advised of potential problems with specific software and games. Intel is actively working on solutions for these issues and plans to release further updates to enhance driver stability and performance.

Highlights

• Launch driver for Intel Core Processor N-series and Series 2 (Codename Twin Lake, Raptor Lake-H Refresh, Raptor Lake-U Refresh).

Fixed Issues

Intel Arc B-Series Graphics Products:

• Skull and Bones (DX12) may experience an application crash while launching gameplay.
• Certain capture cards may exhibit visual artifacts in some scenarios.
• Tom Clancy’s Rainbow Six Siege (DX12) may experience lower than expected performance.

Intel Core Ultra Series 1 with built-in Intel Arc GPUs:

• Call of Duty Modern Warfare III (DX12) may experience flickering during gameplay.

Intel Core Ultra Series 2 with built-in Intel Arc GPUs:

• Call of Duty: Black Ops 6 (DX12) may exhibit black shadow corruption in certain scenes during gameplay.

Known Issues

Intel Arc B-Series Graphics Products:

• F1 24 (DX12) with XeSS FG may exhibit certain corruptions and applications crashes
• Application may crash when dynamically changing XeSS FG settings during gameplay. Recommendation is to toggle XeSS FG settings in the game menu before starting a race.
• “Alt + Enter” shortcut may change the display mode to fullscreen exclusive, which is not supported in XeSS 2 and may cause the game to crash.
• MLPerf may exhibit intermittent errors when running on multi-GPU system configurations. It is recommended to disable integrated GPU as a workaround.
• Topaz Labs Photo AI may exhibit corruptions with certain image enhancement operations.
• Magix Vegas Pro may exhibit corruptions when using style transfer feature.
• Dassault Systèmes CATIA may experience an application crash when using HQAO option.
• Adobe Lightroom Classic may experience lower than expected performance. Workaround is to set recommended preferences in the application
• Under Edit, Preferences, Performance options, choose Graphics Processor as “Custom”
• Select “Use GPU for Display”, “Use GPU for Image Processing” and “Use GPU for Export” options.

Intel Arc A-Series Graphics Products

• Call of Duty: Black Ops 6 (DX12) may exhibit darker than expected shadows in certain campaign scenarios.
• Topaz Gigapixel AI may experience intermittent crash while exporting images.
• Intel Core Ultra Series 1 with built-in Intel Arc GPUs:
• PugetBench for Davinci Resolve Studio V19 may experience errors intermittently with benchmark preset set to Extended.
• Davinci Resolve Studio v19.0 may experience errors while rendering OpenVino test scenarios.
• Topaz Video AI may experience corruption when exporting videos after using some models for video enhancements
• Intel Core Ultra Series 2 with built-in Intel Arc GPUs:
• Adobe Premiere Pro may exhibit corruption in the output video after performing 8K AV1 Encode.
• PugetBench for Davinci Resolve Studio V19 may experience errors intermittently with benchmark preset set to Extended.
• Davinci Resolve Studio v19.0 may experience issues while rendering certain OpenVino test scenarios.
• Davinci Resolve Studio v19.0 may experience errors intermittently while rendering certain AI/ML scenarios.
• Topaz Video AI may experience corruption when exporting videos after using some models for video enhancements.
• Horizon Zero Dawn Remastered (DX12) may experience crash during gameplay with frame generation enabled.

Intel Graphics Software Fixed Issues

• On some system configurations the frequency of windows reconfiguration in IGS is higher than expected and may take longer after sleep.

Intel Graphics Software Known Issues

• Intel Graphics Software may experience a very intermittent application crash when navigating pages or dialogue boxes due to an underlying framework issue. A fix will be made available in IGS once WinAppSDK 1.7 is available for upgrade. The application can be re-launched without issue as a workaround.
• When using the settings, preferences, reset all settings option in Windows 10 the application may experience an intermittent crash. Settings can be reset from individual pages without issue.
• Intel Graphics Software may sometimes experience a single application crash on the first re-arrange of metrics within the select metrics window. Subsequent usage will not be affected by this crash again.
• FPS Limiter may not limit FPS with VSync ON and Low Latency Mode enabled.
• Profile controls don’t always supersede global controls.
• Display scaling at non-native panel resolutions might result in unintended scaling.
• Intel Graphics Software Performance Tuning (BETA):
  • Intel Graphics Software Performance Tuning is currently in Beta. As such, performance and features may behave unexpectedly. Intel will continue to refine the Performance Tuning software in future releases.
  • In multi-GPU scenarios with two performance tuning capable devices, the performance tuning page may attempt to apply changes to one or more devices at once rather than individually based on the GPU selector.
