used Game Source for XSplit and Game Capture for OBS
Apples to oranges, Gamesource is AWFUL in sc2 unless you are streaming at a lower resolution (etc 960x540) with 1.2 optimizations.
I dont have any up to date benches, but i still have a couple of txt files from a run of the same replay, OBS screen capture vs gamesource @960x540, 60fps output, 4x run of already loaded and played through then reset replay in an old beta build for xsplit, showing 37 minimum, 80 average FPS from OBS and 71 min, 121 average for gamesource at that resolution. Tests can be biased both ways.
I plan on making a thread with detailed benchmarks at a dozen different settings, graphing frametimes, average and minimum fps soon if i can, until then unless somebody wants to put work into some fair and thorough testing (with pm's) id like to keep away from performance war or derogatory comments towards either. Its clear that r/starcraft have already made up their minds on the matter from that thread you posted, and its just not a fair bench at all. They literally chose the worst performing option available for xsplit, and the best for OBS.
Probably going to get lynched for this, but i at least want graphs for lots of different settings and capture methods. I understand that OBS seems to have better performance for a lot of people in a lot of cases, but there is a lot of misplaced hate and hype that i really dont like. As it stands i use xsplit for ladder streaming, because it gives me the best performance by far for lower resolution streaming, but gamesource definately only works with select games for higher resolution and framerate streaming, and screen region capture seems to at best rival OBS, but i dont think its right to burn everything over it. Its not bad software if you use it correctly, and definately has at least a few advantages.

This. is. AWESOME!
Xsplit with an Avermedia GamerHD capture card - 720P @ 60 FPS = FPSdrops down to 30 in game.
OBS with regular screen capture - 1080@60FPS = stable 100 FPS (Though i've put the framecap to 60 in Sc2 now)
Thank you for this awesome piece of software!

Screen capture vs gamesource is not apples to apples, Game capture vs gamesource is!
Game Capture is also not always the best for OBS.
The only biased test is your one.

^I dont think game capture works in the same way that gamesource does, it seems to be more of a process capture, especially since it can grab firefox/skype. Performance is also vastly different between the two in different cases, whereas OBS screen capture or game capture seems to act similarly to Xsplit's screen/process capture. It's not the thing to test in a high resolution+fps streaming enviroment between the two programs.
I know i sound like a dick and this is out of place in the OBS praise/support thread, but i am sorry for that and i just want this cleaned up preferably in a non-messy way right now. Both programs have their advantages, ones which need to be measured, and i dont think its fair to throw out xsplit just because of a popular opinion formed almost entirely by people without any technical knowledge. Il support OBS where it is due, i tried to help out some in this thread, it seems to be the highest performing option for single PC streaming for the upper end of settings (1920x1080 @45-60fps with heavily oc'd 3570k - stock 3930k) and it is an amazing program being free, but a lot of the comments and hate towards everything else are just so unjustified. It really bothers me.

I don't know what you have against OBS. It's so clearly better I question your motives in this thread.

Better in some cases, not all. I just got really mad at all of the false claims of some magical encoder that uses half as much CPU as xsplit's implementation of x264 to provide the same resolution, fps, efficiency etc, and everything else that came with it from the hordes of people even more uneducated than myself who know nothing better than bandwagon hopping and circlejerking over every new piece of software, particularly from r/starcraft. I probably wouldnt even be so mad if it didnt happen with FFsplit too, but it did. Whats next?

Better in all cases when properly configured. Xsplit can't come close.

How would you set up OBS for optimal game performance for an etc, 960x540 stream of sc2, so i can update it and provide several benchmarks? Features aside, i am reasonably sure Xsplit has a sizeable lead here, and if not we can say OBS has better capture performance at all resolutions and framerates. I wouldnt mind that, but it's not something i saw when i last tested. Im not sure its such an absolute victory

Cyro, you or anyone can always feel free to talk with me directly, I don't mind. Seeing as I am the guy who originally made the app and everything. But I would just like to say something toward this before this gets out of hand. (I apologize to others on the thread for this slight derailment)
Listen, I personally have nothing against anyone, xsplit, ffsplit, anyone. I have never really had any actual intent to "compete" with anyone at any serious level. I just don't really even care. I appreciate all the kind words and all the things users have said, but the truth is, what the users say and do is of their own volition. I am not running a business, nor do I intend to with this app. There is no need to have some sort of war over what is better than what, because I have nothing to gain.
Would you like to know the truth about why this program exists? It exists because I am a sad, bored individual who has nothing but free time on his hands. The one thing in this world that I can do decently well is program. I grew up programming, both my brother and I did together. It's like the one thing in my l can do well in life. I take immense joy in programming and building things, especially when they're challenging things. I remember writing crappy BBS software at 12 in turbo pascal despite the fact that I had no idea what I was doing, and when I had it partially working (never got it fully working), the joy was immense. I live for that feeling, it's exhilarating, like climbing a giant mountain.
When I started writing this program, I felt that there was a severe lack of information about streaming technology. I wanted to figure it out, it seemed fascinating, and I wanted to eat it up and know it, and then share it with others. I didn't really think that any of this would really happen. I just wanted to make an app and share my knowledge, and hopefully it would spur more open source development in the streaming world as people learn from it and begin to grasp the technology. Admittedly it would be nice to have on a resume as well, if there is one thing in the world I can gain from it.
The reason the app performs as it does is not because of the encoder. The encoder has jack to do with it. Absolutely nothing. I didn't even write it, and I've never even touched the code in the encoder. The reason my program performs well is because I am very skilled at graphics programming, and programming in general. I spent the last 12 years, over a third of my human life doing nothing but graphics programming, making game engines, learning about hard core graphics and CPU optimization, doing everything imaginable related to graphics programming. Graphics programming is my specialty. I applied this knowledge to the streaming application, and it worked out very well.
And that's all there is to the story. I am not out to get anyone, I do not actually really care about competing, I am not really trying to win any fight. I am not really trying to take down xsplit, or anyone. I have no disrespect towards xsplit at all (as of yet). I just was bored, and wanted to make a free alternative.

OBS can serve as a very important catalyst for the streaming community because the existence of a popular, free, open source alternative puts a lot of pressure on the XSplit team (the leading name in streaming) to improve their product. As a collective group of streaming enthusiasts, we all win.
Jim deserves a LOT of credit for not only managing to (unintentionally) compete with the entire XSplit team, but doing it as a hobby and without demanding any respect or donations. He's honest with the community, seems to genuinely CARE about his work, and doesn't hide behind any marketing BS like I've seen from the XSplit reps.
Thanks, Jim!

Hey guys,
and thanks obs.Jim for this wonderful piece of work! 
I can stream in 1080p/60fps and high-ultra ingame settings fluently.
I just got one problem: My upload is really unstable and im dropping a lot of frames!
My internet: 100mbit down and 6mbit upload, so there should be no problem.
What can cause this "problem"?
-- My specs:
CPU: i5-3570K @4.40GHz
RAM: 8GB Corsair Vengeance DDR3-2133
GPU: GeForce GTX 460
Quality: 10
Bitrate/Buffer: 4000
Resolution: 1920x1080p
FPS: 45/60
and GameCapturing

Hey Jim!
I just popped into this thread to thank you. I've recently tried out OBS and it's been great for streaming with my entry-level PC. Thanks for making this program, you are awesome and I just want you to know you are helping a lot of people!
Again, thanks! + Show Spoiler +Looking forward for the next update that hopefully fixes the twitch to youtube upload!

Brainyac - Not entirely sure. Could just be that you're above your "lower limit" in terms of stable data transmission. The truth is you just have to play around with the settings until you find that "right place" were you have good stability and like the quality. Also don't be afraid to lower the quality setting, people think that they have to have it at 10, but truth is it's usually better to have at like 5-8 in most cases. Lowering it also helps prevent pushing hard at the bitrate as well.

Will use this guide later.
I'm also using a 7800 series but with a 3770k @ 4.5ghz so the processor is better. Will aim for 1080p/35 fps

Hey, I made an error in the initial XSplit recording. I failed to have Aero enabled for Game source. This definitely made a difference, though the end results are still pretty much the same.
Still, I did slightly misrepresent, and it is worth rereading. Please spread the word to those who may have already read this piece. Would really help out to comment on and/or upvote this post so that people can get a second chance to read what's going on.

How much should I OC to be able to stream with a 3570k at 720p60fps with minimal lag(Not dropping less than 30fps in intense fight at least).
|
You dont need to overclock to stream at that quality, if you want to stream 1080p 45 fps then i'd suggest OC'ing.
|
Which Bitrate/Buffer should I take for 1080p 30 or 60fps?

But the CPU will eventually have some frame drops while streaming...Is it possible to maintain the frame rate at 60fps the most possible even though it's not OCed??

I just wanted to thank everyone who was involved making OBS. I was in search for a streaming soft ware for quite some time and finally found what i was looking for. My problem with all of them was that i had huge lags during games while i was streaming. It was playable but i really couldn't play without tiny command delays etc.
At this point i wanna say that i used XSPLIT before and i was always wondering why it required that amazing amount of hardware to do something "simple" like recording live and broadcast it. I don't have the best but also not the worst computer on the planet and i was really close to upgrade my computer processor (i5-2500k) to improve my stream. I tried the craziest settings, read through several guides on the internet and suddenly half a year later i find this thing called obs.
I installed it and it was very easy to set everything up. I was able to use allmy overlays i used at XSPLIT too but with one difference. 0 lags at all... it really is like playing normal, i dont even notice that i stream at the same time and that is a thing i was always raging about when i used XSPLIT because as mentioned before, i had slight delays at commands etc and there were moments in games where i lost becuase of it. I played faster then he recognized my command inputs which sucked pretty much in a heated game..
While OBS streams in menu i'm at like 140 FPS, when i'M ingame it's the same. When big fights etc happen or i hit rly rly reaaaally lategame, then i'm at around 70 or something like this. It's a difference to XSPLIT like day and night and i wanna say thx to R1CH here too because i randomly hit this thread to find out what obs is and i agree on everything he says in this thread. OBS is like 10 times better than XSPLIT in every aspect. I don't know how i could use that sh** called XSPLIT before, not to mention that it costs a ton of money and burns cpus lifetime massively while providing way worse performance and picture quality.
OH, for those who are interested:
i5 2500k (not overclocked!!! so i5-2500k @ 3.3)
8GB Ram
Nvidia 285 GTX
<- Running SC2 + HotS on 720p laggy-ish (XSPLIT), with OBS i get the same FPS as while not streaming: 70-140 FPS.
