Error creating RTX Context

I have all the required drivers installed for OptiX 7.1.0 and had successfully Generated the SDK build using Cmake in Windows System with NVIDIA Quadro K600, but during the debug process I get the following errors:
1.“Error creating RTX Context”
2. Failed during compiling “scene.cpp” in sutil.

Please read the OptiX Release Notes (link below the OptiX download button on the developer site) before setting up a development system for OptiX.

The NVIDIA Quadro K600 is a Kepler GPU based board which is not supported by OptiX anymore beginning with version 6.0.0. Only Maxwell and newer GPU architectures are supported since then.
Means you’re limited to OptiX SDK 5.1.1 on your system configuration.

Hello Sir,
Can you please let me know what is the minimum requirement for Graphics card to run OptiX 7.1.0 perfectly so that I can upgrade my system,
As I tried OptiX 5.1.1 on Quadro K600 but I think it is not able to render during the debug process. I can only see the black screen.

You can find tables resp. links to tables listing the GPU architecture per NVIDIA graphics boards on these Wikipedia pages:

Related product pages on NVIDIA sites:

All boards with Maxwell, Pascal, Volta, and Turing GPU architectures are supported by OptiX 7.0.0 and 7.1.0.

Products with RTX in the name are based on the Turing GPUs with ray tracing cores, which means they support the ray tracing acceleration structure traversal and triangle primitive intersection in hardware. They will perform better than any of the previous GPU generations when comparing equal product levels. Additionally the more VRAM the board has, the better.

Means boards from GeForce RTX 2060 upwards to the highest end Quadro RTX 8000 (48 GB VRAM) today would be recommended for GPU ray tracing.
