Question / Help FPS drops in the stream but ingame fps is fine?

[Sebastian]

So as the title says. The FPS on the stream seems to drop all the time. Sometimes it goes very smoothly and sometimes it drops annoyingly. Is there anything I could do about the matter? I know that my PC setup isn't the strongest around but I mean, my FPS ingame is still fine while streaming so what might be the problem in this case? Is my setup just limiting the streaming capabilities simply too much? I've played with the settings. Lowering them and whatnot but it doesn't seem to make difference. It says that FPS is set to 40 for some reason though I had lowered it to 30.

How are you viewing your FPS output? From OBS, or from Twitch.tv's flash player? OBS should tell you the correct output.

You SHOULD have OBS on a higher priority (pretty much always) than your game. So set OBS to high, and game to normal. After that, if you lose ingame fps, turn down your CPU Preset in OBS.

 

[Sebastian]

I had a friend to watch the stream. I'll try out what you suggested.

 

[Jack0r]

The log is unfortunately incomplete, please try to upload the new one, after your test. For the priority stuff dacoder mentioned, it is normally never necessary to do this. And touching the preset is the very LAST option to try.

Seeing that your CPU is not the most powerful anymore you could downscale one more step or two. (In the cut off part of the log you already lowered the fps to 30, keep it at that)

 

[vbdkv]

I've only seen this happening with the 32bit version, which you seem to be using. Try the 64bit version instead, it's in the OBS\64bit folder.

I shall. I actually tried streaming on hitbox.tv and my stream is smoother there. Also I put the actual resolution to 1280x720 and no downscaling at all. It seems do good to the stream as well. I'll see if I can put the full log of that and you can see how it looks?

I'll actually download 64bit version and see if it improves something. I've always wondered why I was using 32bit. :P

 

[Jack0r]

Sure, just post us a complete log after you stopped streaming :)

I believe this should be a full log? o: I went back to 45 FPS because I think the stream feels a bit smoother with it and it doesn't seem to affect my FPS ingame. If it does, then just slightly. Anything worth mentioning on the log? What about the bitrates? I think I had like 4,6 Upload when I checked it on the so claimed better site to check the upload speed.


http://pastebin.ca/2688563 <- That should be the full log, no? Had to upload to pastebin since couldn't post the whole log in here.

 

[Jack0r]

Yea it looks quite a bit better. You sometimes still have a duplicate frames, but they shouldnt be too noticeable.

 

[vbdkv]

Total frames encoded: 3480, total frames duplicated: 117(3.36%) is a problem. I suggest lowering your fps to 30 because your CPU obviously can't keep up.
Total frames encoded: 38433, total frames duplicated: 1244(3.24%) That's quite a lot in the long run.

Example:
Total frames encoded: 139820, total frames duplicated: 16 (0.01%) would be ok.


Bitrate, if you have the bandwidth for it, should really be around 2500 at 720p just to get a decent looking stream. Of course it largely depends on the game you play. For instance I can stream Fear 2 at 1300kbps and it still looks amazing even at 720p. If I switch to Civ 5 for instance, it'll look absolutely awful using 1300kbps. So yeah, depends on the game :)

 

[Sebastian]

Thanks for the replies once again. I'll be going with 30 FPS. Having constant FPS is always better than having any significant drops. c:
