I would like to setup 1 of 3 things for streaming. A seperate pc with 1 cpu, an hpc cluster, or a separate pc with dual xeon cpus. What I want to know is how one would actually set any of those up in terms of just OBS
 
Probably not viable for a HPCC. The other two options would just be computers with capture cards.
 
But how does one set it up? And would OBS be able to take advantage of both xeon's?
 
Install the capture card, connect a second cable from your GPU to the capture card, then duplicate the display in your video card's control panel. Or get an HDMI splitter. x264 can take advantage of both Xeons but multithreading is only going to take you so far. I don't know what your goal is for resolution/frame rate/preset but unless you have some more exotic aspirations for that hardware a dual Xeon box is probably not worth the investment as a streaming box over something like a 4960X or 5960X.
 
M'kay. The goal basically is to utilize the Slowest CPU Preset at 1080p with 60 fps, which is also why I asked about HPC Clustering, that's not a possibility at all?

Keep in mind that's the goal, not sure if possible though. I also noticed that NVENC is as nice or almost as nice as the Faster Preset and can handle high motion scenes better, is that normal?

nvenc should be way worse, but a haswell cpu encoding with qsv is at some points comparable with x264 faster preset
 
I know it should but I find it hard to tell the difference between the two. I mean MAYBE it could look like the Very Fast Preset, I don't know.

if twitch wouldnt have deleted all the stuff i could shown you a comparison from 2k bitrate to 4k bitrate going up by 250bitrate for each vid and going from 720p30 all the way up to 1080p60 also on different presets for everything ... made a shitton of videos :( stupid twitch

i pretty much tested everything but i wasnt at home when they deleted all the stuff so i couldnt download it to save my hard work
 
I'm actually testing right now as we speak and for fast paced games, x264 medium doesn't look as nice as High Quality (Any of the three), I'm testing out Sonic Generations in with Modern Sonic at 1080p at 60FPS with a 2200 bit rate and buffer. Maybe it has to do with the Maxwell architecture. *Shrugs*
 
Yeah, dude, I seriously do not know why, granted I'm happy not trying to complain, Nvenc HQ Low Latency (Not the 2pass one) looks just good as the x264 Fast CPU preset, I tested the same scene 100 times over, very identical. Why that is? I'm not sure, but I am extremely happy about that, OBS Team, thank you so much.

To my knowledge this is not possible with current hardware (my reference here is helping a friend with a dual Xeon E5-2687 streaming box), would not look good for high motion content within Twitch's bitrate limitations, and is inadvisable due to Flash player performance issues with 1080p60. You would be wasting a huge chunk of money on an unattainable goal that wouldn't even perform well for viewers.
 
Can you get an HPC cluster with a DX10-compatible GPU powerful enough to handle scene composition? I don't really know much about them but I assume graphics hardware is not a priority.
 
I can get multiple ones yes actually, but the key goal would be to use it for x264 in unison.
 
Ah well, I might as well forget about it. Lol Like I said Nvenc is working and looking great for me so might as well.
