NVENC to throttle or not to throttle ?

[DingoPD 5]

I just stuffed old GTX970 card in the emby machine (debian) and i've seen up to about 15x speed improvement over pure CPU (2xE5620) transcode. And now I've got a couple of questions about how the transcode scheduler works if you folks are willing.

From what i was reading, 970 has a limit of 2 streams for encoding. That made me think about what exactly happens if there's more than two transcodes required at a given time. Does the transcoder work in chunks and just swaps between the different streams as needed, or does it open a stream and then keeps it open until the whole file is transcoded?

Either way, it seems like disabling throttling now that the transcode is done in hardware could be beneficial. People rarely start watching things at the same time, so there's a chance that one transcode would be done before another one is required. And if the transcode works on chunk at a time, then it'd be able to switch in between them faster?

Thanks

Always throttle but google "nvidia transcode patch" and unlock your GPU.

Yeah i found it when i was looking for info about how the transcoding works. Though i haven't really found much, my duck-fu must be off today.
