NVIDIA quietly increased NVENC limit again from 5 to 8 concurrent encodes on consumer cards

just an FYI for those of you who care, latest driver updates have increased the limit for concurrent encodes on most consumers card from 5 to 8. It previously was 3 last year.

Me who doesn't own a Nvidia GPU - 

        

        I see that as an absolute win.

I recall there was speculation this might be related to the multi-streaming Twitch are introducing. There was concern if there is enough encoding capacity on lower models, especially at higher resolutions/bitrates.

Oh! It wasn't a memory issue, it was a software limitation issue.

 

I previously thought I was running into VRAM limitations while trying to encode a bunch of music loops to mp4 for YouTube. Would have been handy a few weeks ago...

 

Is it just changed with a driver update?

it never was a memory issue.
 

How are you running into VRAM limitations when encoding or decoding? Or how did you that was the case? During encoding and decoding a small chunk of media files are processed, never the whole media. You can in theory have the same encoding and decoding performance if memory layout stayed the same but capacity was 512mbs.

When trying to start more than 5 concurrent ffmpeg sessions it would fail with "Out of memory error".
