Can AMD FidelityFX™ parallel sorting be used with Nvidia and Intel graphics cards?

[ShaoyuanLi]

Hello, I am doing a project about 3DGS. I need to use GPU-based quick sort to sort GS points.

Commonly used 3DGS uses bitonic sorting, and radix sorting is also a good choice .I found that FidelityFX™ Parallel Sort might be a better option, but has some application issues:

• FidelityFX™ Parallel Sort require DX12 and Vulkan. Are there any GPU Features requirements that are not necessary?
• Does FidelityFX™ Parallel Sort itself have relevant performance benchmark data?
• Will FidelityFX™ Parallel Sort also work properly with other graphics cards such as Nvidia and Intel, or is there a risk of poorer performance?
