Question / Help Choppy Stream

you first did that based on other factors which are somewhat irrelevant to the case. the bitrate is the only valid argument lowering the fps even to 30 isn't really gonna kill it. look at the mlg stream for example. preset "faster" 30 fps an rts game. and barely making it at 3300.
 
Thank you for all the information and insight. It's been extremely helpful, and very well appreciated!

After doing some extensive testing (more than 6 hours worth), I have settled with these settings below...

Quality: 10
Bitrate: 2500
Buffer: 2500
Audio Codec: AAC
Audio Bitrate: 96
Resolution: 1280 x 720
FPS: 60
Process Priority Class: Normal
x264 CPU Preset: Fast

These settings have been giving me 100% smooth quality (in terms of consistent frame rate during the live stream). However, there is some static pixels, but it can still be overlooked by the average viewer. As for 1080p, I can easily do 1080p @ 60fps, but only with Diablo 3 and League of Legends that it works very well.

World of Warcraft and DayZ look TERRIBLE with 1080p. There is so much static pixels (although, text and still images are crystal clear).

My new goal now, that I would like to achieve, is to somehow fix the static pixels that I am getting with my current stream settings. I would like to stay with what I am using now, but if there is a way to improve on it and to greatly reduce the amount of static pixels, that would be amazing!

I don't if it's just me, but I've noticed that other 720p streams look much better than my own 720p. I'm guessing they're using a 4k+ bitrate.

Looks like I'll be doing some more testing. I am going to try and improve the image quality of my stream, and at the same time, staying under 3000 kbps bitrate.

EDIT: I can do 1080p @ 120fps, CPU preset on Slow, and Process priority class on High, and I still get a consistent 40+ fps in my games.
 
Even with fast, 2500 bitrate is a tad low for 720p60fps which could explain some of the pixelation.

Also, if you are only getting 40 or so FPS in your game while trying to stream 120fps...you're not actually producing enough game frames to make it worth streaming at that framerate.

True.

I just finished testing a video. I set my Preset to Slow. The static pixels were actually GONE! to my surprise. The stream looked MUCH better!

However, there is some minor "stutter" throughout the stream. But I wouldn't say it's "choppy."

Any idea why it's suttering?

Final Settings:

Quality: 10
Bit-rate: 2950
Buffer: 2950
Audio Codec: AAC
Audio Bit-rate: 96

Base Resolution: 1920 x 1080
Resolution Downscale: 1.50 (1280 x 720)
FPS: 60
Disable Aero at start-up: Check

Use Multi-threaded Optimizations: Check
Process Priority Class: Normal
x264 CPU Preset: Medium
Bind to Interface: *I'm using my computer's ip address*

Ultimately, after HOURS of testing, my settings are now 100% finalized, as follows above. This is the BEST and HIGHEST quality stream that I can produce (when combining my limited 4k upload and the 2600k CPU).
 
There is FPS jitter all over the place in that VOD. You really should not be using Medium preset.
 
I found a simple fix to the problem for myself.
Change the game from fullscreen to windowed fullscreen.
Worked for me.
