I'm having a problem working with GPU in the node

[gilushon]

Hi, this is an amazing node, so thank you for it! I did all the steps in your YouTube video to install Cuda. I'm having a problem working with GPU in the node, so it is very slow. I have I9 computer with 32 ram, and RTX 4090.

this is the log error,

Error occurred when executing DeepFuzeAdavance:

@gilushon With 4090 it should work so fast, this error you shared it seems it's a cuDNN and CUDA installation problem. Also for some reason when you install CUDA one of the dll files in the bin folder is missing. I added information in the error section on how you can fix that and there is a CV error section as well. If none of those worked follow the YouTube video for fully uninstalling your CUDA and reinstalling it.

Sam, Thanks for the quick reply, I did what you wrote about the fix under RERRORS, and it solved the problem.

(Missing zlibwapi.dll error: Search for NVIDIA zlibwapi.dll file, download it and copy it in C:\Program Files\NVIDIA (GPU Computing Toolkit\CUDA\v11.8\bin\zlibwapi.dll)

Now the rendering is 20 times faster. Just one more thing, (in the lip-sync node) I think the frame enhancers don't work, because you don't see any differences between them, the same goes for the enhancer, you don't see any differences between them.

@gilushon i checked it, enhancers are working
