Hey I've been working on making a traffic surveillance system for my client. I tried to integrate your UltimateALPR in my project, I wrote reco2.py which simply use rtsp and apply your model on it, a modified copy of recognizer.py. 

The file runs very well but for some reason its performance is really poor because itsn't using NVIDIA RTX 4070 I have.

I did install 11.8 and respected tensorRT& Cudnn mention in Readme files but its not utilizing my GPU.

Following is the message I got.

```
message: [UltOcrRecognizer] Your GPU supports CUDA and your OCR module isn't GPGPU optimized to run on TensorRT.

I really like the inference speed the ultimateSDK has, and I had really like to bring this to my client's software. And I had more than willing to buy the license but I'm not getting the inference speed as its been promised from ultimateSDK. Therefore I had like to request a small support on how do I configure it to make it work my GPU.

Looking forward to your reply.

Regards,
Hassan Revel

Use the Benchmark sample app to evaluate the speed. And share full logs (DO NOT CUT THE LOGS like you did)
