Question / Help Severe stream lag core i7 920 / GTX 680

angelsg · Dec 23, 2013

Good morning,

I am attempting to stream a handful of games at 720 / 1080p 60 FPS. Previously I was running a single monitor at base resolution 2048x1152, and I was able to stream League of Legends at that resolution without too many hiccups, didn't have to lower many of the in game settings.

I have since reformatted my machine, after installing a Samsung EVO 840 series SSD. I am running Windows 7 on it. I have started playing World of Warcraft again and would like to stream but everytime I try to stream the lag makes it unplayable.
Even when attempting to stream through monitor capture, and just pointing to my desktop, the stream is extremely laggy.

I have a standard EVGA GTX 680, a core i7 920 that is OC'd to 3.6 ghz, 16 gigs of ram at 1300, and all my games and OBS 64 bit installed on the 840 EVO SSD.

I have tried a bunch of the initial troubleshootings that I have found browsing other theads. Aero is enabled, I do game capture when attempting to capture WoW, the audio is lowered to below 160, I try to do resolution downscaling to 720p, I am out of ideas at this point.

Below is my log of a test today that was a few seconds. Thanks for the help

Monitor capture with Aero enabled is the worst possible way to capture. I'm also not sure how well your CPU can keep up with encoding 720p using the fast preset. Try a new scene with nothing but a game capture source, and if you still have issues test with the preset and faster and veryfast. Post new log files if the problem continues.

ColterTV · Dec 23, 2013

Don't use monitor capture with Aero enabled and Windows7, it will bring your performance down (OBS itself should have warn you when adding it, you ignored the warning?)
Also your CPU is a little old so I would say don't mess with the preset, keep it at veryfast

You say you wanted to stream at 60 fps but your logs shows 30 fps. I don't recommend 60 fps with that CPU, but I guess it doesn't hurt to try and see

angelsg · Dec 23, 2013

Thanks for the quick replies. I was aware that monitor capture with games was not great I was just doing it as a test. I changed the preset to very fast, and it appears to be working just fine. The quality is a bit blurry -- anyway to resolve that?

Also in regards to increasing the performance to do 1080p / 60 FPS in the future, I was looking into purchasing a 4770k for myself for christmas. Would that be able to handle the job?

ColterTV · Dec 23, 2013

I'm yet to believe that with 3500 bitrate you have a blurry image :D
Have a VOD to see it?

4770k is the top of the line I think so it will be a great upgrade!

angelsg · Dec 23, 2013

I am streaming right now to test you can view it for yourself.

ColterTV · Dec 23, 2013

The bitrate is too high for me to see it right now, i'm in the office :)

angelsg · Dec 23, 2013

Is it possible to lower it and still make it crisp?

ColterTV · Dec 23, 2013

For 720p @30 2500 is a very good bitrate and more reasonable. If you go too high some viewers will have problems keeping up without buffering

Gotcha. Thanks for all the help and quick replies!
