Question / Help OBS/Elgato Streaming/Gaming Computer Issues

I have an issue that has cropped up recently and I haven't been able to resolve so I hope somebody here can help.

I have a 2 computer setup for a couple of reasons: 1) to ease the burden of my gaming computer from having to process all that video and 2) for a bunch of games (like Witcher 2 I bought from Gog.com) OBS doesn't find it in the Game Capture menu regardless if it's in windowed or fullscreen mode. In fact, on a 1 computer setup I am forced to use Monitor Capture which drops my FPS substantially. Thus, I got an old computer up and running and, with the help of my Elgato HD, I am using it to stream (HDMI out from my gaming computer into the Elgato HD, USB out from Elgato HD to my streaming computer running OBS).

This worked fine but every now and then it seems to clog up somewhere causing my FPS to go crazy, frames to drop and the encoding process to slow down. Sometimes the video just freezes completely. My webcam and microphone - which are directly connected to the streaming computer - still work which make me think this is an Elgato HD issue, but I post this question here just to make sure.

// WHAT I'VE TRIED
I have lowered my setting to the baseline minimum: Video downscaled from 1080p 1920x1080 to 720p 1280x720 30FPS Lanczos (best detail, 36 samples), Video encoding at 2000 kb/s, Audio encoding at 128 kb/s AAC 48kHz. Everything else I've kept the same (I haven't touched anything under the Advanced tab).

I've tried everything in the prior threads:
- https://obsproject.com/forum/threads/dropped-frames-disconnecting-lag-read-this-first.8870/
- https://obsproject.com/forum/threads/high-cpu-usage-taking-too-long-to-encode-read-this-first.11641/

- I've put more RAM into both my computers
- I've upgraded my modem to the DOCSIS 3.0 which is the fastest modem my ISP provides
- I have the fastest internet speed that my ISP provides
- I have restarted all systems, unplugged devices and waited, etc.

I should also note that this doesn't occur every night. Prior to the last two nights (where it froze and was so choppy I had to stop) this setup worked splendidly. I disconnect this setup and use Xsplit on my 1 computer setup (because game capture mode DOES work with Xsplit) and it works perfectly fine.

Here are my computer specs:
// GAMING COMPUTER
  • 3.4 GHz Intel Core i7-4770
  • 24 GB DDR3 Ram
  • EVGA GeForce GTX 750 TI Superclocked
  • 2 x 1TB HDD
  • Windows 7 Professional
// STREAMING COMPUTER
  • 2.93 GHz Intel Core i7-870
  • 16 GB DDR3 RAM
  • ATI Radeon HD 5750
  • 1TB HDD
  • Windows 7 Professional

Is it the Elgato that's just fudging up? Is it my computer hardware that can't keep up? If it's my hardware, why doesn't it happen all the time? Why doesn't OBS Game Capture work like Xsplit's game capture? I do know Elgato has a 3 second delay when I capture my Wii U that only gets longer (up to 5 seconds) the more I play and stream so there are issues there.

So many questions... can somebody help me find an answer?
Thanks for any help anyone can provide.

I downloaded Xsplit on my streaming computer with the same setup and was getting the same video response as with OBS so it's my determination that the issue must solely lay with the Elgato HD and not the software. I'm not sure if it's a defective unit or if it's just the way Elgato is but, as I've said before, I've run into and read a lot about delay issues with the system so it might be the norm with the device. I'm tossing the Elgato in a corner, choking up the money spent as a loss and calling it case closed on this one.

A log file from when the issue occurred would be useful - https://obsproject.com/forum/threads/problem-make-sure-to-post-a-log-and-or-crash-dump-howto.97/

Please keep in mind that OBS does not support 1080p output from the Elgato. It should be running at 1280x720, which means that setting your base resolution to 1920x1080 and then downscaling is a waste of resources. Have you tried completely uninstalling the Elgato software and then reinstalling it? Tried connecting it to a different USB port? Does the same problem happen in Elgato's software? It does sound like an issue with the unit itself or with its drivers if the problem happens in XSplit as well.

If you do decide to ditch the Elgato altogether you would be much better served by a good internal capture card, USB 2.0 external capture devices are generally pretty subpar and totally unnecessary if you have a free PCIe 1x slot in your encoding PC.
