Hi LuxCoreRender Team,
I am Mohammad Aamir Afroz from Qualcomm. We are currently validating LuxMark v3.1 on Windows on Snapdragon(ARM64) laptop. During validation, we observed that the application launches and runs, but on our Windows on ARM platform we see functional differences when running in OpenCL GPU mode (versus CPU mode). We wanted to check with you whether there is any roadmap or plan for official Windows ARM64 support (native build and/or validation), and if yes, whether you could share an approximate ETA.
Environment (high level)
Platform: Windows on ARM (Snapdragon X Elite) Laptop
LuxMark: v3.1 (Windows x64)
Execution: x64 emulation
Observation (summary)
CPU mode runs as expected
GPU mode completes but the benchmark reports image validation failure (large pixel mismatch)
Summary of Findings:
• LuxMark launching under x64 emulation.
• In CPU mode (Microsoft Basic Render Driver), the benchmark ran without any validation issues.
• In GPU mode, using Qualcomm Adreno™ X1-85, the benchmark completed but failed image validation:
• Scene File Validation: ✅ OK
• Image Validation: ❌ Failed — 576,706 pixel mismatch (90.11%)
• Benchmark Score: 6872
• Devices Detected:
• Adreno™ X1-85 GPU [GPU, 6, 1 MHz]
• Adreno™ X1-85 GPU [GPU, 1, 12 MHz]
Request / Questions
• Do you have any plans to provide a native Windows ARM64 build for LuxMark (or validate LuxMark on Windows ARM64)?
• If a native build is not planned, is there any recommended configuration / newer branch / workaround for improved compatibility on Windows on ARM?
Windows on Snapdragon adoption is accelerating, and native or emulation-friendly support would significantly help users.
Qualcomm:
CEO sets bold vision: PC Compute to become a $4B revenue powerhouse for Qualcomm by 2029.
Rapid market penetration: Captured 10% share in just 12 months in premium segments.
Accelerated growth trajectory: Projected 3M units sold by 2026 - achieving in 2 years what competitors took 6 years to accomplish.
We appreciate the work your team is doing on LuxMark, and thanks in advance for any guidance you’re able to share.
Thank you for your support.
Regards,
Mohammad Aamir Afroz
