Isaac 2023.1.1 standalone starting up time problem

[Simplychenable]

here are threads that provide addition information to your inquiry about repeated shader compilation that could be worth checking out:

the explanation from the dev -

Running OIGE or python standalone examples cause raytracing shaders to recompile every time

Hi. The shader cache may have different locations when running from Python instead of the Launcher. The path should be in the log file. Usually, clearing the shader cache and re-running should solve most issues. The shader caching issue could also be caused by other configs or driver version too. By default, Isaac Sim on Windows uses DirectX to render but enabling the “–vulkan” flag will force it to use the Vulkan API instead (Note: this Vulkan runtime library is included in the NVIDIA GPU dri…

solution -

Isaac Sim Python App Not Caching Shaders, Waiting for compilation of ray tracing shaders for RTX renderer

I solved this by adding --vulkan to the python.bat command line: ./python.bat my_script.py --vulkan I remembered that adding --vulkan was suggested for a solution but can recall where I saw this or what exactly --vulkan does.
