Question / Help Loosing frames with x264

[icebreaker90]

Hi guys,
I'm new here and i'm trying to learn how to stream my game sessions on twitch.
My pc configuration is this:
-I7-4790
-16GB of ram
-Asus Strix GTX 970

My internet connection is 50/10 and it should be sufficient.

I've tested the quality of the stream with all the encoders (nvenc, quick sync and x264).
I'm trying to use this last since, as far as I understood, it's the best.
Unfortunately, with that encoder the stream looks good but it looses lot of frames even if my cpu load is about at 70% (so no throttling) and temperatures are ok.
If I stream with quick sync or nvenc I don't loose frames even if quality is not as good as x264 (at same bitrate).


Thanks

Rescale only in video settings.
(I think log does not register if rescaling is checked in poutput settings)

Or try 30 fps

This does not fix the problem... I tryied on 30fps and still loosing frames.

Run OBS 64 bits. Copy shortcut, edit it and hook it to 64 bits OBS exe.

And:

10:34:16.974: target_bitrate: 3000
....
10:38:29.378: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 849 (1.2%)

You are having network problems. Or not enough bandwith

Bitrate 3000 + sound = 3192 Kbps

I've tested obs 64-bit. And, for some mysterious reason, it makes almost every game crash.

Plus that network problem came up only with x264 encoder. With nvenc I can use 3500 + sound without dropping a single frame..

Again, thanks for any hint you will give me.

With worse PC, I got good performance with NVENC. See my profile info.

I got good performance with NVENC and quicksync. 0 frame lost and decent quality. But I wanted to use x264 since it provide better quality at same bitrate.

I've tried with another broadcasting software and x264 works perfectly, no frames lost and stream is not choppy at all.

I'm guessing is an obs bug at this point. I'm going to test it again when some update will be released.
thanks
