V-ray for SketchUp - Frame Buffer Issue

Hello,
I have a question about a UI difference in V-Ray for SketchUp 7.2.2.

Both systems use:

  • SketchUp 2025

  • V-Ray for SketchUp 7.2.2

The only differences are OS and GPU driver:

  • PC: Windows 10, NVIDIA driver 576.80

  • Laptop: Windows 11, NVIDIA driver 581.57

On the PC, the V-Ray Frame Buffer Exposure:

  • still shows Highlight Burn

  • has no numeric value fields (slider only)

On the laptop:

  • Highlight Burn is not present in Exposure

  • numeric value fields are visible

  • highlight control appears to be handled via Filmic tonemap

The laptop looks like it’s using the new VFB (v2), while the PC seems to fall back to a legacy VFB, despite using the same V-Ray version.

Questions:

  1. Can an older GPU driver or Windows 10 force V-Ray to use the Legacy VFB?

  2. Would updating the PC’s driver likely fix this?

  3. After updating the driver, is a V-Ray reinstall necessary?
