If you're willing to use tg-develop's fork instead, then most optimized:
If you're not using the index file: set the chunk size 80ms.
If you're going to use it, set index to 240ms (it might need to be set higher if you have a large model)
Set extra 2.7
Go to advanced settings, and set the following:
protocol: rest, crossfade 0.15, force FP32 activated
download crepe-tiny(onnx)
Exit, then set your pitch extractor to crepe tiny (onnx)
swap processor unit to cpu, then swap it back to your AMD GPU (RX 6900XT) -- this will fix a bug.
For audio settings: Choose server mode: set samplerate to 48000hz, pick wasapi as audio driver.
Set output volume to 180%
set your mic as input. Cable Input as output; monitor driver wasapi as well, and whatever you want to listen to it with.
Open up task manager, go to the details tab and find audiodg.exe there.
set the audiodg.exe priority to High.
set audioidg.exe's affinity to only Processor 2 (disable the other ones)
These settings should work for you for most rvc models
