dxr renderer test

Prompt

write a standalone dx12 renderer in c++ with DXR/RTX. The program should be able to load and render fbx/obj models drag and dropped into it. Users should also able to setup lights like directional, spot, point, area and HDRI lights. Apply dxr shader/materials onto those objects with texture maps and tweak parameters similar to what is offered by realtime renderers like marmoset toolbag. Users should also be able to have control over basic settings like fps limit, dxr quality (ray count, denoising, GI only mode, GI + raytraced reflection ect).
