Saw this blurb in the Opitx 6 SDK EULA, which implies it might be export controlled, but I can’t find an Export Control Classification Number (ECCN) associated with the Optix SDK. Given that anyone with an email address can register/download Optix SDK directly from nVidia for free, and the bulk of it its runtime libraries are now included with the nvidia proprietary driver (at least in Linux), doubt it is, but thought I’d check. If an ECCN for Optix SDK does exist, how does one find it?
