Initializing optix problem

[ggoodd]

When I was using GPU rendering, Initializing OptiX renderer...frozen.
I used two computers for testing. They are both equipped with RTX 4090 and have the same driver. One of them works normally, but the other one has problems for some unknown reason.
V-Ray Benchmark also had the same problem, I found that the memory would get stuck there.
I reinstalled Windows 10, but still no solution. Is there any solution to this problem?
Thanks for your replies!

Thanks for the post!

Drivers 560.xx and 555.xx have issues, could you please try with the recommended Nvidia driver?
What about the CUDA engine, does it work for you in the benchmark?
This could be a problem with your GPU in the second machine, is it a new GPU?

Best,

I have solved this problem by downgrading the graphics card driver version to 555.99 and the problem no longer exists.
Of course, I reinstalled windows 10 again, and then tested the driver versions one by one from the lowest to the highest 560.81. This problem seems to only exist on the RTX 4090. I have another computer with an RTX3090 using the 560.70 version and everything is fine.
I usually follow your articles, especially those about GPU equipment and optimization. I have benefited a lot from this and thank you very much.
