I just tried a game of Dirt 3 while streaming. It's as smooth as glass. No perceivable stutter, input lag, or any other issues. The CPU gets pegged even higher- around 70-80% across all cores, compared to SC2's 30%. I'm really scratching my head after this test... Were you gaming online? And is that game fair to compare with SC2 in terms of CPU load and network communication-wise? I'm not sure. However, if you want you can do a similar test in SC2, try playing "vs. AI" (use the 'custom game' button under "Single Player"). I find this much less sluggish (units are more responsive) when streaming. Which supports the fact that SC2 is hard to please when streaming online games. @Upload speed: It is my experience that @720p/30fps you will see upload spikes going up to about 1.4-1.5 Mbit/s, but the far majority of the time, it will stay way below 1 Mbit/s. Your viewers may experience lag during big fights though this can be limited with the quality setting. Yes, theoretically a maxed out upload will interfere with your gaming experience (by eating all bandwidth), but with 1 Mbit/s available it will not be a consistent delay (because you use much less for the most part).
I've tried both playing SC2 on ladder and against AI... both feel exactly the same.

Just to make it clear, did you use the "Single Player - Play versus AI" feature? The one in "Multiplayer" is significantly slower for me. I believe the first doesn't use the internet at all/isn't connected to B.net - the difference is really quite noticeable (do also try without streaming). If you don't feel any difference, I'm honestly baffled

I've been having the same issues as a lot of people in this thread. i7 920 @ 3.8GHz, 6GB DDR3 RAM @ 1600MHz, EVGA GTX 275. I can run pretty much any game at a great fps but if I try to stream it whether it be with XSplit, FMLE, or Procaster, I get awful video lag that makes streaming games frustrating. I have 25 Up/Down and have tried reducing the bitrate, the quality of the stream, game settings in games I stream. Nothing works.

@Lafali
Have you tried the feature in XSplit called GameSource? It captures using DirectX which gives better performance than the traditional frame-capture method. However afaik it's only available to subscribers.
|
No I have not, I plan on subscribing to XSplit soon though. I don't get how I see streams at great framerates all the time especially when its people with lower specs than me and whatever I stream looks awfully choppy.

I have posted about the same thing on XSplit forums. So here is the deal and a short term work around for the issue...
Most of you have computers which are more than powerful enough to stream at your selected settings but it is causing you to have in game FPS drops even though CPU is at a cruising speed while broadcasting.
If you have the head room as far as CPU usage goes, bump up the broadcasting FPS to 60fps or higher if you can. It will increase your IN GAME FPS AS WELL. This is not a long term solution, and terrible news for people streaming with lower end comps as it does eat up a ton more CPU usage but hey, it is what it is. I went from 30-40 FPS in LoL to 45+ which is at least playable. I am not running the fastest machine either... a stock 965 Phenom.
I have not tried using Game Source yet as I am not a subscriber and there is no guarantee that it will fix this issue, although people seem to be "hinting" that it makes in-game FPS better. Someone needs to do the research. And much like the OP, I am very sensitive when it comes to in game inputs and FPS drops, any FPS drop is considered unacceptable to me in LoL. It blows my mind that people can play with 30fps all day and not even notice it, but I guess we all have our preferences.

Interesting suggestion.
But bumping the FPS from 30 to 60 will require twice the bandwidth, or reduce the quality by 50% using the same amount of bandwidth. However if you have the extra resources this may help those of you who think playing at ~30 FPS is bad .
The GameSource feature is going to change this (I predict) - according to my tests I get 30-45 ingame FPS when streaming at 30FPS *and* the ingame sluggish unit control is gone. . GameSource is said to shine on high quality streams - Source

HellGreen, so if I am reading you correct your are currently using GameSource and still only getting 30-45 fps, just with better unit control? What is your CPU usage while broadcasting?
|
@interspool
Yes, that is correct. It's sitting around 60-65% (with quality=10, 720p, 30fps, default preset)
|
I have a personal license for Xsplit, used GameSource, had no difference.
It's still in beta, obviously, so hopefully we'll see a greater improvement next revision!

Just built another computer. Stock i7 2600. Streaming 720p @ 25fps and in-game in LoL I am getting 60fps. It is butter smooth and if I pay close attention to the CPU usage, Hyper Threading DOES come into play. CPU usage on any one core (including the HT cores) never rises above I'd say 65%. This results in a fluid stream as well as a perfect in game experience.
I made a post about this on XSplit forums as well. Previously I was 100% certain that running a stream in 25fps would result in no more than 30fps gameplay. Turns out I was wrong. I don't know if I have a faster computer, or Hyper threading to thank, but this does not seem to be the case any longer.

I guess there is something on wrong on my end, then. I've got an i7 @ 3.8GHz, 6GB DDR3 RAM @ 1600MHz, and a GTX 275. I get perfect fps in SC2 and LoL when I'm not streaming but the fps drops a good bit and there is video lag when I stream, nothing is smooth even if I do happen to have 60 fps.

(OP) UPDATE: Since my last post, I've since moved, and also completely switched my ISP. I was at 12 Mb down, 1 Mb up. I'm now at 20 Mb down, (and more importantly) 2 Mb up. Speeds tested and verified multiple times.
Result? Nothing has changed. This all but kills the silly theory that internet speed has anything to do with local, in-game framerate issues. I (re)-tested with both Xplit and my very conservative Adobe FME settings.
As interspool posted above- this definitely seems like a CPU issue, but an odd one as those of us with the common i7 920/930 in question rarely see CPU utilization get pegged, even when streaming. Nevertheless, it seems that those with the latest Sandybridge architecture are in great shape.
If any of you i7 920/930 users out there figure out how to have a decent stream while getting 60+ FPS in SC2, please share your settings with us. Otherwise, I'm shelving the whole idea of streaming until my next PC upgrade, which will probably be a while from now.

My suspicion is that this is a memory or cache contention issue, possibly limited to a particular stepping of CPU.
Really difficult to prove though. If it's true, decreasing the number of threads used for video processing should help a lot, but you probably can't handle 720p with a single thread without massive overclocking. Increasing memory bandwidth may help. Removing a memory stick and dropping to dual-channel would be an interesting test.

Destiny streams with a 930 clocked at like 4ghz or something like that, have you contemplated overclocking?
If I can stream with a q6600 a first generation quad core with minimal lag IG you should be able to stream

Yeah, if you look a few posts back (no fault to you, this thread is huge), you'll see that I tried that. I'm up to 4.2 GHz and holding. No change.
I think in his case at least, it might be that he was just able to overcome it with skill. For me, I can't stand the feel of the frame drop *at all*, especially for something like SC2. It's gotta be 60 FPS or I'm not doing it. I'm curious to know what FPS he gets/got with that system (CTRL-ALT-F). At the moment, I hover around 40 FPS, but it definitely "feels" even worse.

Just as dTox mentioned, dxtory works great.
I am running the trial version right now and i get absoultely no in game performacne drops
As mentioned, the downside is that I will likely have to pay for it.
My only issue now is that my stream is very choppy
Xsplit says I am only uploading at 500 or kbps but my connection is 5 Mbps upload so I am a little lost, but hopefully I can fix it
|
Is anybody else getting this problem where Xsplit won't let me add a camera? It worked fine the other day and now there is no "Add Camera" option at the bottom and "File -> Add Camera" doesn't do anything.
Edit: Nvm, it started working again...

But maybe its best to just keep it to this thread
