Sorry if this has been answered somewhere before, but I searched for hours and could not find a conclusive answer. | ||

HT definately doesnt help game performance in standard cases, and shouldnt be noticable at all unless you are attempting extreme settings (no reason to if you have a capture card, better performance and you are limited to 1920x1080@30fps/1280x720@60fps which is like half of what an overclocked 3570k can pull off in sc2) | ||

You're the only reasonable person I've read that didn't have some extreme answer like "OMG can't stream without hyperthreading!!" or "HT does nothing, forget about it, wasted money". Wanted to ask a bit more to clarify on your previous response. By extreme I'm guessing you mean extreme setting in SC2 right, not "extreme graphics" in general? What did you mean by the capture card comment? Do the extreme settings imply a higher resolution or something (sorry, haven't logged on SC2 in a few months...getting back into it soon though with a friend) that the cap card wouldn't be able to grab? I'll be using the capture card to at least capture my PC screen as I've read its way better than software and I may even try the onboard encoder, but I've heard it outputs garbage compared to having your processor do it. As far as the hyper threading impacting gaming, I was more talking about a hypothetical game that ended up taking up enough of my processing power that combined with encoding, would have the processor hit 100%. Would hyperthreading then kick in and allow some more headroom for both the game and encoding, or does it not work like that? What if I wanted to go to a slower preset...like say medium or slow. Would the 3570 then start to struggle at 720@60fps? Planning to OC to 4.5 - 4.7 Reading through this thread on the x264 presets, it seems like going to the "slower" presets gives a better picture, but taxes your processor more, and the lower you get, the less benefit you get at each step, while the processing power required increases even faster. That's true right? So I wouldn't I want to get the fastest processor to try and get the slowest preset so everything looks better (for 720p that is), or does it also not work like I think? I think I read some post that said it doesn't necessarily look better the slower you put it... Thanks for the help, sincerely...I'm pretty much clueless atm regarding most of this. | ||

Would hyperthreading then kick in and allow some more headroom for both the game and encoding, or does it not work like that? I guess so, but no game actually runs like that. GW2 is by far the most CPU intensive game i know of on 4 cores (using like 70% average), but due to performance reasons you cant actuly run a 60fps stream anyway. If you are maxing out the game on a 3570k / hd7970 system, you will have like 40fps minimums due to CPU in just regular play without anything special going on, and at best, you wont make that any worse by capturing and encoding video What if I wanted to go to a slower preset...like say medium or slow. Would the 3570 then start to struggle at 720@60fps? Planning to OC to 4.5 - 4.7 The presets dont give anywhere close to linear returns though. Its something along the lines of getting 20% more efficiency at the cost of 300% of the CPU power needed. 20% from Hyperthreading generally wont help you out much - id get it if you were trying to push for X resolution at Y fps while not going above Veryfast preset (good efficiency up to there, and then very sharp drop offs) but nothing else really. With OC'd 3570k stable 1920x1080@60fps@veryfast should be pretty easily in your reach for sc2 (the limits of most people watching your stream, 1920x1080@60hz refresh) At 1920x1080@30fps or 1280x720@60fps (capture card limits) you should have a lot of free CPU for playing basically anything, you could encode at a lower preset if you wanted like 10-20% gains in efficiency (quality at the same bitrate) but HT wont really help you push that further much at all. Its a small plus but one you will never notice for gaming+streaming unless you are really trying to get the last 10% out of your system. | ||

I have about 1.1mbps upload and have set both my bitrate and buffer to 750, should I be doing it any differently? Buffer decreases the blurr that you get when you move the screen about, that's all you need to know. It's usually a good idea to put it ~200 above your bitrate for a game like sc2 if you have excessive upload to support it. In your case you do not, so i wouldn't advise it. | ||

I might try to play around with that setting, may increase it by 100 or something small. Thanks. Its also reccomended to keep it the same as bitrate for a whole lot of reasons. A small increase wouldnt even be noticable, but if you use VBR with a bigger buffer than can be handled you can get massive spikes in bitrate output that will lag out the stream and/or game in this kind of use. | ||

Been using Obs the last few days in place of xSplit (my licence will expire soon). i can't seem to get a very clear and neat stream, here's my conf : - 12 GB DDR3 PC12800 (1 600 Mhz) - i7 980X - 3.5Ghz (first 6cores) - Radeon HD5870 - 1024Mb GDDR5. - I have a SSD for the system, but SC2 is on a standard 1TO SATA3 disk. Here's the speedtest from my home : http://www.speedtest.net/result/2365031013.png You can see some of my later streams here : http://www.twitch.tv/growiel . As you can see, the stream is good, but doesn't look HD while i'm streaming 720p. Oh, my native resolution on my 26" main monitor is 1920*1200 . What settings would you recommend ? Keep in my mind that I am NOT a partner, so while I can send 50Mb of bitrate no problems, almost no people would be able to handle it and see my stream correctly. Thanks in advance. | ||

What standards are you referring to when you say it doesnt "look" HD? HD is pretty much defined as 1280x720 which you are manually setting. If you are trying to fullscreen the video or view it in a larger window than 1280x720 (upscaling) then it will probably look awful regardless of its quality. Try using www.twitch.tv/yourchannel/new, that gives you a stream window a little bigger than 1280x720 when you view on 1920x1080 (as opposed to the 2.25x upscale required to fullscreen it) You should be using the max quality setting available, im not sure if you can override ratecontrol in OBS (xsplit limits you to crf25 which is pretty awful unless you use command line) use somewhere around 3-3.5k bitrate and buffer for streaming at 1280x720/1920x1080 and id strongly suggest running the game in 1920x1080 (with screen/video drivers set up for black bars at top and bottom) so you can capture the game in the same aspect ratio you are streaming at (16 : 9 is FAR more common than 16 : 10 in monitors these days) and also because of the way that SC2 scales the game window. You see more area with a more "zoomed out" view at a 16 : 9 resolution compared to 16:10, which cuts some off the sides of your viewport. For bad looking stream: - Wrong aspect ratio - Bad ratecontrol setting limiting bitrate - Upscaling video somewhere - Too low bitrate etcetc. | ||
