No GPU support for translation yet, but as of 0.4.4, RapidOCR can now be run with the GPU. Hopefully that increases the speed somewhat on your PC!
Fortunately, or unfortunately, the slowdown isn’t OCR (which is already impressively fast); it’s the DeepL translation that’s killing responsiveness. I know you’re focused on OCR perf, but from my end, that’s not the bottleneck.
Examples (0.4.4)
⬆️ The translation Online with DeepL
⬆️ The translation Offline with Internal Engine
This is one of the many reasons why an internal model is the preferred solution in my use case.
