HD630 GPU seen twice by system

Hi, I am looking into an issue, where the image raw converter Phase One Capture One along with the util CLInfo.exe shows the HD 630 GPU twice.

I have attached the resulting text-file from CLInfo.exe. As a result of this, the software thinks there are 2 cards, distributes its image processing tasks as such, making it very slow performing.

System Setup Information: -----------------------------------------

System Used: MSI GS73VR 7RF Stealth Pro

CPU SKU: I7-7700HQ

GPU SKU: HD630 System

BIOS Version: E17B1IMS.310

CMOS settings: N/A

Graphics Driver Version: 21.20.16.4534

GOP/VBIOS Version: 86.06.18.00.18,6291456

Operating System: Windows 10 Pro

OS Version: Version 10.0.15063 Build 15063

API: N/A Occurs on non-Intel GPUs?: No

Steps to Reproduce: ------------------------------- 1. Run CLInfo.exe util or Phase One Capture One and expect logfiles 2. Observe OpenCL device being detected twice for the HD630

Expected Results: Only 1 instance pr GPU should be found ------------------------------- Actual Results: 2 instances pr GPU found ------------------------------- Additional Information: -------------------------------

That's expected behaviour.

One CPU device, one GPU device.

You need to tell your target application which one to use.

Either via command line option or from some menu as seen e.g. in http://www.ozone3d.net/redirect.php?id=401 GPUCapsViewer

If it ain't documented, ask the developer e.g. here:
