OptiX 5.1.1 precompiled samples on GeForce RTX 3060 do not work

Good morning, I’ve changed computer and I’m having problems porting my program to Optix 6.5 as the selectors have been removed and I’m having problems with shadow calculation.

I wanted to try with Optix 5.1 but if I use the NVidia examples they work on a GTX 1660 Super (desktop) but not on a GeForce RTX 3060 Laptop.

If I run “optixDeviceQuery” (Optix 5.1.1) I get

`OptiX 5.1.1
Number of Devices = 1

Device 0 (0000:01:00.0): NVIDIA GeForce RTX 3060 Laptop GPU

while instead if I run “optixConsole” I get

OptiX error: Unknown error (Details: Function "_rtBufferCreate" caught exception: Encountered a rtcore error: m_exports->rtcDeviceContextCreateForCUDA( context, devctx ) returned (2): Invalid device context)

Do I have any hope of using Optix on my new PC? (I don’t want to port the APP to Optix 7.x it would be too expensive…)

Grazie

OptiX 5 is not supported on Ampere GPUs. It’s too old for that.
The OptiX core implementation moved into the display driver with OptiX 6 to handle that going forward.
