Sorry if this has been posted before but id like to add something:
Some guides recommend setting affinity so your streaming program and SC2 run on separate CPU cores. I don't really recommend this as it just limits performance, if you want to ensure your SC2 doesn't lag at the expense of your stream, simply set SC2.exe to High Priority in task manager.
Running with affinity set will get you VERY consistent results, and allow you to optimise advanced settings more, whereas running without it but with sc2 on high will change the amount of processing power that xsplit has access to, even if it potentially frees up more room for encoding, you wont have access to that all of the time, so it is worthless for heavily optimised settings that would try to use it frequently and fail, dropping frames.

considering investing in dxtory it seems sweet but i dont think my system should need it?
2500k @ 4.4ghz
8gb ram
5.5mb upload to local servers on speedtest, 3.8mb cross country (seattle to florida lol)
sli'd 560 448cores
looking to stream 30fps full 1080p

Great read, well done R1CH

I cannot recommend Dxtory enough.
I have a new machine I built in September. Specs are:
i5 2500k OCd to 4ghz
8gb GSkill Ram
GTX 570
SSD HD
etc etc Fast machine.
30/30mb internet connection
I could not get ANY satisfaction with xsplit or FME even on the lowest settings my computer would chug a shitty 360p video and drop input frames out the yin yang.
I bought dxtory and instantly I can push out 720p video at 1200kbps (very low) and its flawless.
Buy that software!

My brother is trying to stream games with his 10/1 connection. It's kinda low because of upload bandwith, but what I've read and I also had low bandwith and still got MUCH better quality than he does.
Hardware: GTX 570, 8gb ddr3, i7 2600k
http://i43.tinypic.com/2ntz786.jpg In the picture the player is moving and everything is very pixelated and this is the biggest issue.
He's trying to stream with XSplit and Dxtory.
What can we do to get better quality? Upgrading bandwith is not option at the moment. So if there are any suggestions or need more pictures from his xplit settings I'll bring them tomorrow in the thread.
Thank you! : )

he just needs to have a lower broadcast resolution, the scaling is killing him along with the low upload... His PC doesnt need dxtory seeing as he only complaining about the stream quality. Not Lag at all.

I spent some time today testing various xsplit settings in order to get a better idea of what affects stream quality the most. Here's a brief summary of what I found:
- "Quality" basically doesn't matter. The difference between Q10 and Q0 is very hard to detect.
- Bitrate is super important. The higher you can get your bitrate, the better your stream will look. Obviously don't go too high to the point where you are saturating your upstream and lagging everything or causing your viewers to not be able to watch.
- Preset is also important to tune quality, but it comes at great CPU expense. The difference between XSplit Default and medium was 30% to 85% CPU usage (720p30, 2500k, no game), however the quality did perceptively improve at no cost in bandwidth. I wouldn't recommend changing this if you are playing and streaming from the same PC though as your game CPU usage could vary while you play and cause 100% CPU usage which is never good.
- Increasing FPS doesn't necessarily increase bandwidth required. Because the differences between frames become smaller, they can be encoded more efficiently. If you have an awesome PC but a bad Internet connection, you can use this to make your stream have higher perceptible quality by increasing your frame rate to say 50fps with very little image quality loss. During my testing with SC2 at 1280x720 1500kbps, 60fps resulted in total CPU use of 60-70%, 30fps resulted in 45-60%. Decreasing FPS further (eg 20 fps or below) does not seem to improve stream quality, but does help to reduce CPU use.
- The XSplit bandwidth tester is worthless to test your settings with, the only thing it does is test your bandwidth. This is quite deceiving as it uses the current scene as a test, but ignores your quality and preset settings. Don't rely on the bandwidth tester for accurate results in terms of quality and CPU usage.

hey TL! Ive been streaming fine for the past few months but ever since i got a new monitor i get about sub 30 fps while playing a game. im pretty sure my machine can hande it though:
8GB DDR3 RAM
Diamond 6770
AMD Phenom II X4 965
and with this internet ![[image loading]](http://www.speedtest.net/result/1815772892.png)
before i was running at 1680x1050 now im 1920x1080 but that shouldnt change much right? thats the only thing i could think thats causing so much lag

Is i7-2670QM qualify for a ideal cpu?
I read some thread regarding the speed of this CPU where it is too low to stream.
I mean it is laptop, and I would love to know if this could be good for streaming.

I use a i7-2670QM for broadcasting.
Here's a sample of what I've broadcasted.
Settings:
FMLE
Dxtory
1280x720 @ 30fps, average bitrate @ 2500~3000kbps

Hey guys, been trying to stream at 1080p, but my frame rate seems low any and all help/advice would be appreciated. Specs are as follows:
Core i7 2600k @4.2GHz
12 GB DDR3-1600 Ram
GTX 670 2GB
Internet is Xfinity by Comcast:
![[image loading]](http://www.speedtest.net/result/1954125500.png)
Here is a sample of my 1080p stream with a "poor" frame rate:
http://www.twitch.tv/tbomega/b/318354600
When I stream in 720p the frame rate is fine.

@Tbomega:
I do not have any streaming experience, but I am starting to learn as much as I can because I am planning on doing so in the not too distant future. However, I found the answer to your question in the OP made by R1CH.

Here's some very rough example bitrates you should be looking at for a nice quality stream at 25 FPS (these will vary depending on encoder used and other factors, with XSplit you can get away with a lower bitrate for the same quality for example):
480p (720x480): 750-1000kbps
720p (1280x720): 1500-3000kbps
1080p (1920x1080): 3000-5000kbps+
Most of you will not be playing in a resolution that matches one of these exactly, so you'll likely want to resize your stream down to a matching aspect ratio.
The poor frame rate is probably due to the limited bandwidth.

I just remembered that Speedtest.net doesn't work well on Comcast cable internet, due to something called "PowerBoost" that boost the speed of the download/upload for the first few megabytes. My actual Down/Up speeds are 16mbit/2mbit, so I guess that does put me under the "3000-5000" required for a 1080p stream. Bummer. I don't know if anyone else here is streaming Diablo 3 now, but I can't seem to figure out what is up with it. I can't get vsync to work correctly while streaming it, or get a solid frame rate. Anyone else having issues with Diablo 3?
EDIT: I just recently upgraded to Comcast from AT&T DSL

What quality stream would I be able to reach using this computer with an upload around 1.25-1.40?

you would really be limited by the bandwidth. You would have to run roughly 900kbps which would be kinda crappy in resolutions streamed above 1280*720
a 480p stream would probably be the best thing since your bandwidth isn't all that great. But the processor itself should be able to push 720p no problem.

Do you guys think its possible to stream my game ( at low quality like 480p )
With 4.20 Mb/s and 0,8 Upload!
And with that cumputer :
Intel Core 2 Duo E8400 Wolfdale Socket 775 LGA (@45 nm) 3000 Mhz ( L1I: 2 x 32 Ko, L1D: 2 x 32 Ko, L2: 6144 Ko )
DDR2 Kingston 9905315-019.A02LF 512 Mo PC2-6400 (400 Mhz)
nVidia Corporation:G92 [GeForce 9800 GT]
I know its really bad but i just wonder if its possible because im trying with only xsplit and screen capture but right now im lagging in macro game! so i cant really stream my ladder and real game! :/
I might upgrade my internet for 15/10 so thats would help! but still :/ and i might have a laptop so i was wondering if its possible to play on cumputer but stream on my laptop? well thanks for all those information!

Can anyone help me out with my stream?
i think it's fine on the viewers end but i feel the lag which is the worst.
i got an i52500k
8 gb ddr3 ram
Radeon HD 6770 1GB
i like to play the game on specific setttings. everything on low except a few cpu heavy things on medium changes the graphics a bit and its just what i like personally.
keep in mind that im in newyork. these tests are just as far possible in west and east coast like the op guide explained to do.

ive been going by the bandwidth tester on xsplit but i see you say it means nothing. it was failing around 900 kbps, some times it varies, one day it wasnt even getting 400 kbps. what should i set the bitrate to? and what resolution do you think is okay for me to stream? ive been using 720p. i have a 1920x1080 reso monitor.

I have been trying to stream xbox 360 to my computer which is an AMD Phenom II X4 840T 12gig 1333mghz ram IceQ x turbo 2gddr5 vid card, aver media capture card averC127, my upload speed is 4.5 mpbs on speedtest.net using an HDMI 1.4a splitter with all 1.4a cables. So I have a fairly good setup and I'm trying to stream to twitch.tv/grapplerandrew. I have been able to do FMLE at 1920X1080 at 30 fps as input streamed at 30fps 856X480 1500kbits video up, 224kbits audio up with absolutely no frame drops. But as soon as I try the same setting on my xbox trying to stream 1080 it just goes green image even when I set it to 2.5kbits video and 224 audio and drops frames like crazy. I tried making my xbox 720p input instead and put that and 1500kbits video, 192 kbits audio and then making my stream 720p it would always stream at 60fps and wouldn't let me change the stream to 30 so it would always drop frames no matter what kbit's setting I put it at. I've also tried to do a 1920X1080 in with 1024X576 as the stream same settings as 480p otherwise and it was slightly better but dropped too many frames. Please for the love of god I just want to stream 720p xbox to twitch. Fight Night Champion is terrible at 480 barely watchable no matter what the variable bit rate is set at :<. Should i switch to paying for xsplit or maybe this dxtory or something?

Your CPU is the limiting factor in your quest to stream 720p. If your motherboard is am3 and supports am3+ socket the best and cheapest way to be able to stream higher quality would be to upgrade to a 8120. Its far cheaper to just upgrade your CPU rather than getting a intel cpu/mobo which would output better quality @ higher resolutions. But for streaming xbox @ 720p the 8120 is more than enough.
