denosier crash on 2080 in optix 5.1.1

hi. I just download optix 5.1.1 and run the optixDenoiser sample will crash.
DLDenoiser run method failed with error -40
my machine is 2080. previous 5.1 works fine.

On the download page “Improvements to 5.1.1” there is

Looks like your card is not supported :(

I saw that and thinking it’s just doesn’t support RTX as 5.1 didn’t expect the crash.

I supposed that the release note was referring to the new RT hardware. So, 5.1.1 does not work at all with Turing cards?

Only the commandlist execution will crash. I can still see the image before denoise.
