Nvidia 5080 Not being detected as CUDA GPU

[Dan64]

Hello Selur,

  I have the same problem. Hybrid is not detecting my new GPU RTX 5070 Ti.
  Also NVEnc is not able to recognize it, I opened an issue for this: https://github.com/rigaya/NVEnc/issues/675

  The RTX 50xx need CUDA 12.8, fortunately few days ago was released a pytorch build for windows with CUDA 12.8 support.
  The new pytorch build is using the CUDA library: 12.8.57 and the cuDNN library: 9.7.1.26.

  To be able to use the card with vs-deoldify I had to run the following commands:

.\python -m pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu128

  Moreover in the last torch distribution VapoursynthR70_torch_2025.02.22.7z was missing the package  opencv-contrib so I had to install it

.\python -m pip install opencv-contrib-python

Given that my RTX 3060 has 3584  shader processors (at 1320 MHz) while the RTX 5070 Ti has 8960 processors (at 2295 MHz) I was expecting an increase in speed of at least 3X, but in my preliminary tests the increase in speed is only 2.2X. I had not time to optimize the GPU and mybe I will able to improve the speed further. But at the moment I'm busy to get all packages working with this new GPU.

Please provide me the link to the new Hybrid version supporting the RTX 50xx card, when it will be available.

Thanks,
Dan
