* render-test: Change D3D12 default to sm_6_5 (#8320)James Helferty (NVIDIA)2025-09-02
| | | | | | | | | 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
* Updated support to enable batch3 (#8219)Harsh Aggarwal (NVIDIA)2025-08-20
