I have a question about hardware encoding settings

I have a question about hardware encoding settings.
I recently changed my NVIDIA video board from a GT-640 to a RTX4060Ti 16G
I have changed to a
When I finish editing in SHORT CUT and try to encode, the encoding time is the same as on my old video board.
Is there any setting I can change to make it faster? Or does the time not change that much?
I have not changed any settings since I changed the video board.
Please let me know if there are any settings that need to be changed.
Thank you in advance.

Configure hardware encoding>detect ?
Did you do that?
Also several other factors for export time.
Do you use the same cpu or a different one?

I would not expect a big speed difference because both GPUs are fast for this task, but the architecture of Shotcut (see FAQ) is not entirely GPU-based. It can only go as fast as it can feed the encoder, which is constrained by CPU. However, I do expect there to be a good quality improvement with this upgrade plus it can do AV1 encoding.

Update: you can turn on Export > Video > Parallel processing to try to make it feed the hardware encoder faster.

Thank you for your prompt response.
I have set the export to youtube and use hardware encoding, and in the settings I have chosen the detection item and auto selected multiple encodings.
I think there was only one before.

Sorry, I forgot to mention that the CPU is the same.

Understood. I was able to find the parallel processing setting and will try turning this on.
Thank you all for the advice.

Bottleneck obviously, not in this case because as Dan said, shotcut is not entirely GPU based. A four generation gap is surely a big difference in gpu, you could save up for a better CPU to reduce the Bottleneck. I am not only talking about editing, but gaming, and more stuff.
