    Hi!

    Ray tracing is supported on all NVIDIA GPUs starting with GTX 1060 and with more than 6 GB of VRAM. Just keep in mind that, as the image above states, GTX GPUs are emulating ray tracing and thus are much slower than RTX GPUs in ray tracing effects.

    Probably a documentation issue. We don't test ray tracing on all the GPUs in that list since we don't have them all.
    You can alternatively use tools like GPU-Z that will show a checkmark if ray tracing is supported. If that's the case then Unity will also support that GPU.

    Thanks.

    In HDRP v7.2.1, v8.0.1 GTX 1660 is listed:
    https://docs.unity3d.com/Packages/c...n@7.2/manual/Ray-Tracing-Getting-Started.html

    https://docs.unity3d.com/Packages/c...n@8.0/manual/Ray-Tracing-Getting-Started.html

    And in v8.1.0 even GTX 1650 !
    https://docs.unity3d.com/Packages/c...n@8.1/manual/Ray-Tracing-Getting-Started.html

    It would be nice to write in the documentation, to avoid misunderstanding and confusion, that RT fallback is provides on NVIDIA GPUs with DXR support.
