2025-09-02render-test: Change D3D12 default to sm_6_5 (#8320)James Helferty (NVIDIA)
Changes default for render-test to sm_6_5. Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it. Fixes #7611
2025-08-20Updated support to enable batch3 (#8219)Harsh Aggarwal (NVIDIA)
Enable CUDA support for batch 3 tests - Enhanced wave operations with exclusive support - Added proper identity values for min/max operations - Fixed intrinsic name mapping issues - Updated test configurations Co-authored-by: Ellie Hermaszewska <ellieh@nvidia.com>
2025-08-12Enable CUDA testing for batch 2 (#8147)jarcherNV
Enable CUDA for the tests listed in issue #8078 This requires a minor CUDA prelude change, adding some math functions.
