Im having some issue with my stream using OBS.
Some of my viewers experience a brief "1 second lag" every minute or so watching my stream, while others are perfectly fine and theres no disruption.
I'm using a 720p resolution with a 3500/3500 bitrate/whatever the other one is. My OBS says I have zero frames dropped and whatnot so im not sure what the issue here. My quality setting is also set to 7, and my native resolution is 1920x1080, but i downsize it to 720p due to a lot of people not having the connection to watch in 1080 and I want to be able to stream for the majority.

could be cpu related, slight connection drops that you otherwise wouldnt notice, an issue with the software or something else entirely, pretty hard to say.
You dont have to worry about using lower resolution and not having your viewers being able to watch, if that was a concern you would lower bitrate, and maybe (not always) chose a lower resolution to go along with that.
If you are using 3k/3k bitrate, it does not really matter what resolution you are streaming at in regards to your viewers being able to watch of not - bitrate is the limiting factor, not resolution, people just tend to use higher bitrates at higher resolutions.
What CPU are you using?

I'm using a sandy bridge i5 2500k overclocked at 4.8ghz
so using 3.5k/3.5k bitrate is perfectly fine to stream @ 720p? Would I be able to stream @ 1080p/30fps with that bitrate? Because right now im using 720p/60fps

You can encode any resolution/fps fine with any bitrate, it's just going to change the quality of the video and the file size (not the difficulty of encoding etc)
1280x720@60fps/1920x1080@30fps on veryfast preset are pretty close to the same CPU usage requirements and not even close to aggressive enough settings to be maxing out a 2500k@4.8ghz while playing sc2
Two variables with bitrate, firstly if you can upload it AND your viewers can download it, and secondly its just quality slider with diminishing returns. You dont have to worry about it adding load to CPU or anything like that, just about upload/download bandwidth and the quality of the video with the bitrate you have set (higher = better)
If you have the drops on stream i would try cutting bitrate to like 2000 for a little while to see if the issue persisted (probably wouldnt fix anything), change servers etc, check if you get the issue at the same time in the stream (start of a battle or something like that) but its pretty hard to diagnose

Now that you mention it, the ones that were having the issues were saying that the 'drops' started at the beginning of a fight, and then ended once the fight stopped.

^I'd cut bitrate a bit, try different buffer sizes and max out the quality option (1-10) to keep bitrate more consistently high
3500kbit and potential for spikes is high enough for it to be plausible for there to be issues for quite a few people downloading live from the server (after you sent it to the server just fine) which would explain 0 dropped frames but lag for them if your CPU wasnt maxing out (and it shouldnt be even coming close)

So, set my quality to 10, and bitrate down to 2k, while keeping 720p@60fps? I'm really an amateur when it comes to this technical stuff. What exactly does the 'quality' (1-10) do? And is a 2k bitrate still good enough to stream? The only reason I had it set to 3500 is because I thought the higher it was, the better quality and easier viewing for my viewers. x.x;

*lots of shrugs*
I dont want to give anything that could be seen as bad advice when aparantly so many people dont even want me around any more, you shouldnt have any issues streaming sc2 to a good server at 1920x1080@30fps/1280x720@60fps at veryfast, 2.5-3k bitrate and the right buffer size.
And is a 2k bitrate still good enough to stream? The only reason I had it set to 3500 is because I thought the higher it was, the better quality and easier viewing for my viewers. x.x;
True but maybe a touch high for some. Find a test subject that it doesnt/didnt work for, cutting it a bit will either fix the issue or wont.

Could be an issue with Twitch's servers, maybe your viewers have spyware/virus problems, blah blah etc. If you aren't dropping any frames in OBS and you aren't having any issues with your game lagging/freezing, it's hard to say anything is wrong on your end (especially since you have some viewers that don't experience any problems). But yeah, there's a chance some of your viewers might not be able to keep up with your upload-- like Cyro said, try lowering your bitrate temporarily.

I tried using OBS w/ only 1MB/s upload and...well, it's a hell-uva lot better than not streaming.
VOD: http://www.twitch.tv/thericeagainst/b/353497499#
Internet:
+ Show Spoiler +
CPU: i5 2500 (stock; not 2500K, just 2500)
GPU: GeForce 405 (haha)
6GB RAM, 600Mhz DDR3
Max: 750 kb/s, Buffer: 950 kb/s (should I lower buffer?)
480p @ 25 FPS (but ~20 FPS actually gets through)
Do you guys think I can improve the stream a little more, settings wise? Or should I upgrade my GPU? Or my internet?

after extracting, I can't run the file.

OBS doesn't work on XP, upgrade already  .

The website has only one download link, no option for 64bit vs 32bit. I'm running windows 7 x64 and the program is labeled "Open Broadcast Software (32bit") after i've installed it. Where can I find the 64bit version??

Hey guys I've been having an issue with OBS that I'd love to get some help for.
I want to stream at a lower resolution, because my internet is only decent, not amazing,
but when I go to the video settings, select my monitor and downscale it, the settings simply just do not save - I open the settings up again and it goes to the "custom" resolution of 1920x1080, which is the actual size of my monitor.
I really need to downscale it to not lag, so any help would be greatly appreciated!

Choose resolution downscale 1.5x (or one that fits your needs). Should work just fine (you can lower the bitrate too)
As for monitor not remaining selected , after looking into the code , just selecting it fills the custom resolution with your current desktop resolution values. Quite misleading behavior. Probably that config section needs to be worked a little.

Whats your source resolution?
Id put buffer down to the same as bitrate if you dont have much breathing room in upload
960x540@60fps@veryfast preset or 960x540@30fps@medium/fast are pretty easy picks (that's assuming 1920x1080 source though)
If you are concerned about performance of the game go for lower framerate capture

Don't worry, the downscale is working fine. After you set your downscale setting, the listed "custom resolution" will stay at 1920x1080 but you will output the downscaled resolution. I guess it's a little misleading.
