New Photoshop Not Detecting Dedicated GPU (Uses iGPU Instead)

Hi,

I'm experiencing a serious issue with Photoshop not detecting my dedicated GPU. My setup:

• Laptop: ASUS ProArt Studiobook 16 H7600ZW

• Specs: Intel i7 11th Gen, 64GB RAM, RTX 3070 Ti

• OS: Windows 11 Pro

• Photoshop Version: 26.5 (latest)
  
  

Photoshop runs very slowly because it only uses the integrated GPU (iGPU) instead of the RTX 3070 Ti.

I’ve already tried the following steps:

• Set Photoshop & Sniffer to use high performance in the NVIDIA Control Panel

• Adjusted Windows display settings

• Updated all drivers and Windows

• Clean reinstalled Photoshop

• Contacted both Adobe and ASUS support 3+ times
  
  

Unfortunately, ASUS confirmed the iGPU cannot be disabled in BIOS, so I can’t force the system to rely solely on the dedicated GPU. Adobe support was not been able to help.

Interestingly, Photoshop v22.2 works fine and detects the GPU properly. This leads me to believe the issue may be related to the sniffer.exe tool in the newer versions.

When I removed sniffer.exe in v26.5, there were some performance improvements, but the GPU still wasn’t detected.

Could you please look into this? I would really like to use the latest features in the newest version of Photoshop, but this GPU issue is preventing me from doing so.

Thank you,
