So I switched to xsplit broadcaster + own3d.tv a week ago, because the quality on livestream together with procaster is quite bad.
While the quality is great with xsplit, for some reason it's stuttering real bad when I scroll the screen around in sc2. I wouldn't create this thread if I just had a bad computer and not good fps(aka sub 60 fps).
Problem is I am constantly above 100 fps while streaming and moving around the screen, but it is still not smooth at all. Normally I run the graphics on a mix of ultra/high/med, I switched down to all low and still horrible. I've tried all kinds of xsplit settings such as lower stream resolution, lower quality number and less kbps.
These have all failed to smooth out the stuttering while moving around the screen.
What I've tried, and has made it smooth, is lowering my broadcasting fps to extremes such as 6 fps, and my actual capture resolution to about half of my screen's res (1680x1050). While these smooth it out, the stream becomes unwatchable.
Also I believe these solutions don't solve the underlying problem, as the computer can just muscle out the un-smoothness which is happening.
My computer's specs are as follow:
Intel i7 930 overclocked to 4 GHz
Ati 5850, stock clocks.
6 GB DDR3 ram
Don't have an SSD but that shouldn't matter as much while streaming and not recording on to hdd.
My stream output resolution is 1280x720, upload bitrate 500 kbps, stream quality 6, frame rate 20 fps.
The audio is 16bit 44,100 Hz stereo 64 kbps.
I doubt these specs should struggle streaming sc2 at 1680x1050.
There's no stuttering on the stream but it feels very hindering while playing because of it.
I'd like to hear other streamer's comments on xsplit + sc2 and how their experience is with it.
I'm open to any ideas to try that you might have. Because I love streaming and providing solid play for people to watch and enjoy.

What are your settings in xsplit broadcaster?
bitrate? video quality setting? audio quality setting?
|
Ahh sorry I completely forgot about adding those, I will add into OP.
|
Have you assigned SC2 its own cores and Xsplit its own cores?
|
Yeah I've tried that with different combinations of affinities and priorities, They yield the same performance for me. ;;

Posting here to say I have the exact same problems and I'm running an i7-875K at 3.0 Ghz (quad core). And it is literally the exact same problem. In game FPS claims it is 60+ but it looks and feels more like 20 while playing, especially when panning the screen. I get the exact same problem using FME + VHScrCap. The only software that works for me is Procaster, which has no noticeable effect on ingame performance. I've tried dropping ingame graphics options to lowest settings. I've tried lowering stream quality to lowest possible settings. I've even tried playing with xsplit or FME + VHScrCap running, but not uploading (ie not connected to a server) and the problem still persists. I have spend a lot of time on this problem, b/c I would much rather broadcast to Ow3d.tv or Ustream b/c of livestream's low upload limit.

Do you have the Optimize for Motion Picture setting on in broadcaster?
(Or turned OFF the optimize screen capture setting in plain VHScrCap)
|
Try turning vsync off in sc2 in case you have it on.
You computer should be able to handle the game + stream just fine.
|
I have this exact issue and I'm running an i7 also.
I don't have vsync on or have that optimize box checked.
|
what's your internet connection? Low upload speeds can make both the stream and the game very laggy nomatter what system specs your running.

You DO want the "Optimize for Motion Video" (or something like that) checked in Broadcaster.
You DON'T want the "Optimize Screen Capture" in VHScrCap.

That's interesting because I've done some testing....
"Optimize for motion picture" UNCHECKED: No noticeable impact on game. Stream stutters very bad and frequently black screens.
"Optimize for motion picture" CHECKED: Stream runs fine...Game lags horrible. Capped at about 50 fps but feels and looks stuttery.
Also, vsync is turned OFF in SC2.

Yeah... interesting, unfortunately we're at the limit of my knowledge about that stuff. It has the impact on the stream I would imagine, but I don't know why your computer is crapping out. You have a much better one than I do.
I know this is a huge crapshoot, but have you tried unclocking the CPU?
(For sc2 as you saw you do want that option checked, otherwise the capture driver gets hints from windows about when things change... when windows move etc, which is not what you want.)

Yeah that's what I meant, in VHScrCap.

I have the same problem as you, and I found out what was causing it... It's the windowed (full screen) mode. While streaming on full screen, it runs perfect for me, 0 lag, like I have no streaming running at all. But, in battles, the screen begins to make a lot of flashes and its unwatchable. So I have no option but to put it back to windowed full screen T_T.
In own3d's website you can read this "XSplit Broadcaster doesn’t support Full-Screen capture (yet), you should use your game in windowed (full) mode and you probably won’t notice any difference, but it will make XSplit work." so you can clearly see that it's their problem and that "yet" may say that they already know the issue and are working on it. Let's just hope the fix it soon.

has anyone here come up with a solution yet? i have a similiar problem
intel core i7 2.8 ghz
radeon hd 5870
6 GB RAM
streaming with quality 4, 640x360, 650 kbit and it still doesnt very smooth to play. some other guy sent me a PM some time ago linking me to this thread, but i already tried the optimaze for motion video thta is recommended here and it didnt help. i also changed some stuff in windows settings that turns off the windows 64 special effect thingy in the taskbar (so sc2 is shining through)
|
I disabled the Aero theme and it worked really well. FPS of the stream went from 15 to 30 no problem.
|
Yeah disabling aero in Windows Vista/7 is an absolute must for Xsplit, it simply won't work with it enabled.
|
Have same problem here (and its the same with VHScrap and FME).
The game say it runs over 200fps but it is slow, and dodgy. If anyone have solved this issue please reply:
Computer speccs:
i7-920
HD 4890
8GB ram
|
streaming also depends on your internet connection, if you have a crappy connection, and trying to streaming HD, it will never happen
