Will SSD / high end card like GTX 580 help boost stream fps?

[jincuteguy]

Here is a stream that I did yesterday when I was doing Heroic Magmar 25M in Blackwing Descent with my guild. I was p laying at 1920-1080 and streaming at 1920-1080 with 20fps. The bitrate I was streaming was 6000kbps. The stream looks smooth right? But in the game itself (WoW) during that fight, it was like I was playing at 10fps cause the cpu usage was really high.

Here is the link to the stream video: http://www.justin.tv/jincuteguy/b/284718759

streaming at very high bitrates generally requires a LOT of processor power... 6k could possibly be more than your system could handle without negatively affecting your usability.Ttim does 5 - 10k with an intel 980X but for the most part has been streaming at 5k for several years and it's always looked fantastic.

6k would probably make my system beg for mercy hehe or at least make it annoying enough that I wouldn't favor streaming that much data over usability and say perhaps a 2500k stream bitrate. 1920x1080 doesn't really look that bad at 2500k to 3500.

on a side note it does look fantastic just the framefrate gets a bit jittery when your processor redlines

one other thing i noticed is you have directx 11 disabled in the game's advanced options. if you can support directx 11 you'll find your lag might disappear.

one other thing that will really lag your system is watching your own stream while streaming hehe.

I think it has to do with the version of VHScrcap. Is ther anyway you can upload the one u have somewhere so i can download it? the link in the FME streaming guide doesn't work anymore.

just read the above again and figured i'd do some research on the differences between the 800 and 900 series i7's. the differences are definitely significant with regards to the total memory bandwidth the processors can maintain. just food for thought...

Your 860 spec sheet
Intel® Core? i7-860 Processor (8M Cache, 2.80 GHz)with SPEC Code(s)SLBJJ

Here's an i7 960 quad core. last one before the jump to the hex core i7-970. NCIX has this cpu priced around $339.00 CND. Too bad the 860 requires an LGA1156 socket.

Intel® Core? i7-960 Processor (8M Cache, 3.20 GHz, 4.80 GT/s Intel® QPI)with SPEC Code(s)SLBEU

In reviewing both it appears as if the 800 series doesn't support quick path interconnect or QPI. I could be wrong about your cpu not supporting QPI however. After using a 4.8 GT/s QPI system for a year it's been like someone finally turned the lights on even if i only have a second generation i7-920 with the d0 stepping.

Here's intel's flash demo on QPI Intel® QuickPath Architecture Demo

The thing is I tried at 2000kbps and the cpu usage is about the same. I dont think the bitrate matter, the bitrate i think it's more about the quality. The 860 doesn't have QPI I think cause the memory controller is on the cpu itself. But I dont think there should be a big difference between the two cpus.

Tim never showed his cpu usage in his video during the gameplay so I really don't know how the 980X is. I wished he make a stream where he has the cpu monitor showed in a corner or something.

Yea I know im not suppose to watch my own stream during streaming but it doenst matter . I tried it before without watching my own stream and it wouldnt make much difference.

I know some guy on here with a 2600k and was streaming using Xsplit at 30fps 1920-1080 and no lag. My system can't do 30fps at 1920-1080 using Xsplit. So I'm sure the there's a huge difference between the 2600k and 860 even t hough they're both Quad cores and support hyper threading.

I tried DX11 mode too basically everything I could. LIke I can stream fine doing quest or heroic dungeons, hang around in Org or fly around the world. But if I do anything like massive pvp in AV u know where ther'es like 40+ ppl fighting at the same time in one area, or raiding 25man boss fight, the cpu will crawl. I'm sure Tim cpu will be too if he actually do massive pvp or raiding 25man during boss fight.

I guess all I can say in summary is not all intel i7 cpu's are built as equals. the 1156 is the baby of them, 1356 is big poppa pump, and 2600k is the 1156's newer bigger badder brother...

Intel® Core? i7-2600 Processor (8M Cache, 3.40 GHz)with SPEC Code(s)SR00B

in the end however QPI will always win in a drag race.

while my specialty is more servers, computer hardware and such you might want to post in the FME streaming guide to see if Nghtmr9999 has anything to add. he's been pretty involved with that area of the forums

One other thing i'll also mention is i'm using FME 3.2 despite the recommendation not to.

[jincuteguy]

Yea I tried 2.5, 3.1, and 3.2 thx for all the infos man. I'll just sell this 860 and get the 2600k.

[jincuteguy]

Oh I forgot to ask you if you were streaming at 1280-720? or 1920-1080?

[jincuteguy]

Ok so I went and got the 2600k today and got it installed. And guess what? It's just beat the **** out of my old 860, im like wtf. I thought it wouldn't that big of a diff. Then I went and overclocked right away to 4ghz . And now I dont lag anymore in massive pvp battles, the cpu usage never went pass 55% while streaming at 5000Kbps. Is sandy bridge really that much better? Hmmm I dont know but that's from what I've seen.

[xartin]

glad to hear it

with essentially double the memory access bandwidth per core than the 860 it's no wonder why your not lagging anymore. I'm relieved I didn't buy an 800 series for that very reason.

Ok so I was streaming tonight at 5000Kbps. It was really smooth I even looked at my own stream during the streaming and I watched the record of the stream afterward and there was no stuttering / choppiness / freezing or anything like that. However some ppl who watched my stream told me in the channel chat that the stream was choppy (like freeze every now and then). So does anyone on here know why? I couldn't figure out why some of them said the stream was choppy but it was smooth to me.

I was streaming at 5000Kbps to Justin.tv (here is the link to the stream Justin.tv - Viett - Intent US Kel'Thuzad - ) Do you guys think it could be Justin.tv couldn't handle the bandwidth for the viewers during that time? Or is there any other reasons? I asked those ppl and they all have like 20Mbps connection. I'm really clueless. My stream did not have a single frame drop. I used H.264 with level 5.1 Main at 1 sec Key frequency 1920-1080 resolution.
