May I know what's your goal here?

1) Solve Vulkan error to enable DLSS 2) Solve the Uncaught exception which causes the program to crash

If the goal is 1), you need to download the Vulkan SDK here and install it. Importantly, make sure your CUDA driver is up-to-date (>= 520) otherwise it will not be detected when you re-build instant-ngp.

Don't worry about that. It's worth mentioning that this is just a warning when you do not successfully export Nvidia OptiX in ~/.bashrc. Check your env first, please. :-)

s worth mentioning that this is just a warning

Hi @Dandelionym , when I build this project by cmake , the output log shows system found the Vulkan_path. However, in actual use, the log shows as follows : Could not initialize Vulkan and NGX. DLSS not supported. Thanks a lot for your reply.
