Warning: The PTX version is not supported by the installed CUDA driver.

When trying to run the example at /rendering/demo.py

I get extremely low FPS, and my terminal gets polluted by this message:

[Genesis] [23:01:58] [INFO] Running at 1.37 FPS.
[2024-12-30 23:01:58.754] [console] [warning] The PTX version is not supported by the installed CUDA driver. Trying to patch the PTX to make it compatible with the driver. This might cause unexpected behavior. Please consider upgrading your CUDA driver. [/home/chaow/Morphd-ai/Morphd/Genesis/genesis/ext/LuisaRender/src/compute/src/backends/cuda/cuda_shader.cpp:13]

My cuda version:

~/Morphd-ai/Morphd/Genesis/examples/rendering$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2024 NVIDIA Corporation
Built on Tue_Oct_29_23:50:19_PDT_2024
Cuda compilation tools, release 12.6, V12.6.85
Build cuda_12.6.r12.6/compiler.35059454_0

I had to install CUDA 12.6 per this commment: #203 (comment) which fixed the rendering speeds without ray-tracing.
I understand that current ray tracing is more computationally expensive, but is 1.37FPS normal?

Is the warning i'm getting the source of this slowness?

I'm on a gaming laptop, so probably not the greatest speed either. I believe my card only has 8Gb of VRAM.
