CuDNN 9.x compatibility issue with CUDA 13.1 - Support for newer versions?

[Mikkelka]

Hi,
VoiceFlow runs fine on Windows 11 without CuDNN installed. However, for GPU acceleration with CUDA 13.1 and RTX 5080, I'm having issues:

The documentation requires CuDNN 9.x, but it's difficult to find and download (NVIDIA's site doesn't easily expose older versions)
CuDNN 9.x compatibility with CUDA 13.1 seems unclear

Questions:

Why is CuDNN 9.x specified if the app works without it?
Would the app work with newer CuDNN versions that are more readily available?
Any plans to update to support current CUDA/CuDNN versions?

This would help users with newer hardware get GPU acceleration without compatibility headaches.
Thanks!

Thanks for reporting this! I'll look into the CuDNN/CUDA compatibility situation.

Unfortunately, I don't have access to a 5090 to test with, so debugging this is tricky on my end. If you find a solution or workaround, feel free to open a PR and I'll take a look!

In the meantime, the app should still work on CPU mode if GPU acceleration isn't cooperating.
