Question / Help Huge Frame Drop/Lag after Update?

[ままし]

I am receiving ingame lag and frame drops while playing StarCraft 2 since updating my OBS application. I believe the last known working version was 0.50. [Will double check this later] I useto use highest settings in StarCraft 2 plus streaming a movie at the same time in OBS never restarted my computer either, just used sleep mode with the old working version of OBS, but now I have to use med settings tweaked with lower shadows and such to prevent lag.

Hardware:
CPU 2700k Overclocked to 4.5ghz
16GB DDR3
Nvidia GTX 690
2x SSD Raid0
Win8 64bit
OBS 64bit
30megs down 5megs up

Desktop Resolution 5760x1080 [Plus two more 1080p monitors] [5x monitors in total//all 1080p]
Streaming Resolution 1920x1080 [streams only the game plus monitor]
Streaming Reduced to 720p
Stream FPS 60fps
Game: StarCraft 2 HoTS [Highest settings]
Capture Method: Game source
Stream Provider: Twitch
Extra: Image overlay, movie clips from Media Player Classic, Webcam

Video Quality: 8
Preset: Very Fast [I believe...]

Log has now been attached.

Troubleshooting lag: Restarted my computer with no other applications but StarCraft 2 and OBS, plus no MPC/no movie how stil receiving lag. Only way to prevent lag is lowering settings to med ingame.

P.S.: If I reduced Stream FPS to 30fps, would this help me? Wouldn't this kill my ingame speed, as in reducing my game to 30fps as well? I have had this issue in the past.

Also trying to use desktop input with OBS bluescreens my computer with 5760x1080 resolution. :S

Yes, we will need to see the log before being able to tell you what's wrong.

As for the 5760x1080 resolution, h264 does not support resolutions that large, so you won't be able to record at that resolution.

dodgepong, First off thank you for the super quick reply!! I will read up on how to find my logs when I get home. As for the 5760 resolution, I wanted to shrink it down to 1080p and include other elements on my stream. Is this possible?

Btw, I am also using a webcam. I forgot to include this ealier.

You can get a log here: http://obsproject.com/forum/viewtopic.php?f=6&t=97

If you downscale your full monitor capture down to 1920x360, that might work, but I don't know how well such a capture would work at all. I suppose, theoretically, the largest resolution that h264 would support of that aspect ratio is 4096x768... o_O

I'll try scaling it down again, but last time I selected desktop source it bluescreened right away.

Change the audio encoder to aac and lower the video bitrate to 3000 then enable "minimize nework impact" from broadcasting settings.

Thanks for the suggestion. I am testing them now~!! Will report back soon!

I have been streaming a lot and testing the performance. It's better, but it's still slower then it use to be. My settings are set to mid to high, but the speed is not where it use to be. Any more suggestions? Should I lower the video bitrate lower?

Post a new log file if possible, also make sure that the game is not running on one of the weaker gpu's.

How do change the processes to other [better] processors? Give them higher permission or similar action?

You can select which GPU OBS runs on in Settings>Video, it's the drop down menu at the top.

I have 3 different video cards of course not including the 690 card, two video cards in one. So 690, 430, and on-board video. Should I switch 430 or on-video? 430 is being used for my other two monitors.

Update, Using the other video cards does not help at all. Through troubleshooting, it appears setting obs to another video card allows applications to be ran on that video card/monitor. For example, if I run game1 on video card 2 with monitor 2, obs has to be set to video card2 to render it. However if game 1 is running on video card 1 with monitor 1, but obs is still set to video card2. Nothing should should show up.
