Intel UHD DX11 hardware and driver limitation.
HDRP shaders with 8192/4096 sample loops stall the GPU and trigger a TDR crash.
Suggested workaround: reduce the corresponding shader sample count when targeting lower-end Intel GPUs.
How to reproduce:
1. Open the attached “IN-123783” project with command line argument “-force-d3d11“
2. Navigate to File > Build and Run
3. Observe the result
Reproducible with: 6000.2.6f2
Reproduced on: Windows 11
Not reproduced on: No other environment tested
Notes:
Reproduced environment is from the customer's report.
Not reproduced by CQA after testing on Windows 11
The crash does not occur when prewarming the shaders on DX11 with: NVIDIA 3050, AMD Radeon RX 6800, NVIDIA 5060, AMD RX 7600
