Re: 0.60 test build 7
I tried all settings (manually if necessary to write something I don `t know that)
60 FPS even thought to try because there will be many losses of frames.
And the image at a bitrate of 3500 is not so hot.
If you can show your settings when playing BF4.
(I want this game to set up a benchmark in setting not climb)
sorry for bad english
i tested http://www.twitch.tv/fomadima

Re: 0.60 test build 7
Hello!
Couldn't get the nvenc to work, error popping up when trying to record saying "Encoder initialization failed!"
I tried with both 32 & 64bit, but didn't work. Also I downloaded the ObsNvenc.dll from the page 2.
Here's the log
Nevermind, my geforce experience didn't update my drivers like it should've. got it working ._.

Re: 0.60 test build 7
Hello,
I was curious about the nvenc and tried it for half an hour. So far it's promising performance wise, but it seems I'm the only one really bothered by the compression rate.
I know it has been pointed out on multiples older topics, but how come most of the people here are looking for ways to get perfectly crisp image when I barely can get a normal quality 720p record @ 30 fps?
My first guess is that most of the americans net providers have a higher upload average than me, but I believe I missed something else.
I used to stream at 2500kb/s but my previous CPU was too weak for me to have a decent quality. Now that I have a 4th gen i7 it's doing quite good with x264.
So is the NVENC alternative only good for people with weak CPU and really high bandwidth or can I tweak the settings more than just with a few presets?

Re: 0.60 test build 7
Or playing a game that demands all of their CPU, with nothing left over for anything else, but yeah, that seems about right, for streaming anyways. For local recording NVENC still seems useful, because it doesn't matter much if you crank the bitrate way up when saving to your local hard drive.

Re: 0.60 test build 7
I had finally the time to compare the different encoders and quality settings and yes, this post will contain the captured video & log files.
Gaming PC:
i7 4770k@4.5GHz
Geforce GTX 780
HDMI 1080p 60hz Ouput
Streaming PC:
i7 2600k@4.5GHz
Geforce GTX 680
Avermedia Extremecap U3 Input from Gaming PC (1080p, 60fps)
OBS Settings:
buffer size: 3500
max bitrate: 3500
CFR: yes
CBR: yes
keyint: 60
width: 1920, height: 1080
fps: 30
Used Encoders:
NVENC => All presets
QSV => QuickSync
CPU => medium - superfast
I tried to replicate a real scenario while streaming to twitch and went with the recommended settings on a test drive.
First of all i created some native battlefield 4 1080p 60fps gameplay footage on my gaming pc with shadowplay, i had no framedrops ingame, so it should be a good source. Then i connected my gaming pc with the avermedia extremecap u3 to my streaming pc and started to capture the previously recorded 60fps footage (playback was done with vlc) to compare the quality of NVENC, QSV and x264 cpu.
I was not able to capture 1080p with 60fps with any of the NVENC presets and since 1080p with 30fps is the common default (beside 720p 60fps) i went with 30fps.
You can see the results here:

In the end i've seen the footage more than enough and now cant really tell which quality or which preset is the best :D.

Re: 0.60 test build 7
If i try 1080p@60fps with NVENC HQ i get the message that it takes too long to encode and get ~10-15fps in OBS:

Re: 0.60 test build 7
^^ Download them again. If the custom settings work then it means you were using an old dll. Which would explain why the dropbox wasn't actually enabling different presets.

Right click the scene.
Then click Set Hotkey.
Now press the Key / Keys that you want to set.
When done click OK.
You can now switch to that Scene by pressing your defined Hotkey.
