Question / Help Two GPU config advice

[Vakaloura]

Hi,

I´m trying to figure out what i´m doing wrong, because i asume that it´s me.

The idea is to stream and record at the same time, in the output stream I select the nvenc h264 and GPU 0 and in the output recording nvenc h264 GPU 1 and nothing happens neither stream nor recording, instead I select in both stream and recording settings x264 and both stream and recording are operative but lower framerates and/or frames are lost.

Computer: 2x xeon e5-2637, 2x GTX780

PS Sorry for my english

Disable SLI and try running everything on one GPU and see if that helps. Since SLI renders the frame on individual GPUs and you defined a specific output which can cause heavy stuttering

I believe NVENC on that card can handle two separate streaming/recording tasks, you might try that instead of trying to split the work between the two cards.

thanks for your replies.

I tryied to deactivate SLI, activate nvenc on both streaming/recording, and it wont start to doing so. After that, x264 on streaming an nvenc on recording, recording wont start and streaming going well.

And the last config was x264 on both streaming/recording, as a result recording started and streaming wont, but it when I check the generated file it was empty.

Any further ideas/suggestions?

As you can see "this encoder is deprecated", what it means?

 

[Sapiens]

There used to be an old NVENC encoder that has since been removed from the list and you've probably had that one selected. Switch to a different encoder like x264, then back to the NVENC entry in the list. That should put you on the new version.

Thanks for your advice, i just update the nvidia drivers and all works just fine.
