GPU inference problem but CPU works fine

[CanadianHusky]

Hello,
I am running v6 Onnx models on CPU with

            Dim device As New Sdcb.OpenVINO.DeviceOptions("CPU") 
            device.PerformanceMode = PerformanceMode.Latency 
            PaddleOcrAll.OCRAll = New PaddleOcrAll(FullModel, device)

it works flawless with high accuracy.
When I switch to GPU (on Intel Arc GPU)
Dim device As New Sdcb.OpenVINO.DeviceOptions("GPU")
Inference runs, no crashes, no error messages but the output is very bad.
Some text zones are missed completely. OCR Recognition works in some zones and has totally unacceptable results in some other zones.
Overall it is an unusable result.
Can someone explain this behavior ? What could be done?

I happens to also bought a Intel Arc GPU, I'll debug it when I available
