[Lighting] Failed to find a suitable OpenCL device error is thrown on selecting Progressive GPU light mapper

Progressive Lightmapper

-

Failed to find a suitable OpenCL device error is thrown on selecting Progressive GPU light mapper. Unable to switch to Progressive GPU for the first time.

Steps to repro:
1. Create a new Project.
2. Windows > Rendering > Light Settings.
3. Lightmapping Settings > Lightmapper.
4. Select Progressive GPU(Preview).

Actual Result:
Failed to find a suitable OpenCL device error in the console.

Expected Result:
No Errors in the console.

Reproducible in:
2020.1.0a18, 2020.1.0a17.

Working Fine in:
2020.1.0a16, 2019.3.0f5(4b9e60e5c3e9).

Environment:
Occurs only on Windows.

Stack trace:
Failed to find a suitable OpenCL device, falling back to CPU lightmapper.

  1. Resolution Note:

    This is expected to see the fallback to CPU in 2020.1, since your GPU has 3 GB of VRAM. Starting from 2020.1 GPU Lightmapper requires the GPU with at least 4 GB of VRAM and on GPUs having less than 4 GB of VRAM it should fallback to CPU Lightmapper.

    I'm using Unity 2021.3.13f1 and unfortunately I'm new in Lightmaps generating but when I select the GPU Progressive , gives me the same "OpenCL not suitable" error , Because My GPU memory is also 3GB .

    Can anyone suggest me some hack to control it

    yes please this makes no sense. GPU lighmapper works perfectly fine with 3 GB. We are currently stuck with unity 2019 version because of this reason. At least give us a way to hack it.

    I have the same issue, I almost lose 8 hours by finding the solutions for this error.

    This feels... a little dumb. Is there any way to force Unity to still use my GPU with 3GB of VRAM? I've used this GPU to bake lightmaps in previous versions and it worked perfectly. I really would rather not downgrade my unity version just to bake lightmaps.
