Hello, brand new here. I've been streaming for about 2 months now and I will hit the HIGH CPU usage which I have troubleshooted and I believe have resolved but I have some quick questions. Let me Post my specs real quick.
  • Motherboard: Asus z87a
  • CPU: Intel I7 4970K
  • RAM: 16 gigs 16000 MHZ ram
  • GPU: EVGA GTX 980 Ti
  • STORAGE:Crucial Solid State
  • OS: Windows 10 64 bit
  • MONITOR 1:150 inch projector- Acer 6510BD
  • Monitor 2: ASUS VE278H
With that being said my OBS is ran at all the recommended settings. The resolution is at 720 downscale and bitrate at 2200 @ 30 FPS. For high motion games (dying light, R6 Siege IE IE) Is this about the norm? I also use the bilinear quality. Here is the URL to the stream highlight I made earlier. Is this about the normal quality for non partnered streams? http://www.twitch.tv/roids0777/v/43176129. I guess I'm just looking to get some opinions on the quality of my stream and some suggestions/tips. I personally think it looks pixelated at some points in the game which I might try Bicubic or Lanczos Would increasing the FPS to say 40 or so require more bitrate as well?

Also does disabling the OBS preview help lower the CPU usage? I noticed a difference in cpu usage when I turned it off and also the preview in twitch's dashboard. I would have posted a log, but I am at my office currently.

Thank you

Don't use the Twitch dashboard preview; you should never watch the stream from the machine you're streaming from.
40fps will increase load, and add jitter on 60hz monitors. You want to stick to a full-integer divisor; 60, 30, 20, 15, 12, 10, etc.

If you're getting high load, check the stickied thread at the top of the forum. Also make sure your CPU isn't overheating, throttling, or parking cores. Also that you haven't added any 'best settings' custom x264 bits, as most guides out there are full of used food.

R6S can be kind of CPU taxing for obvious reasons, as can Dying Light. Your CPU should handle 720p@30 on x264 Veryfast no sweat.
Post a logfile from the Help menu (just upload, and paste the link it gives you here) and we'll be able to help further.

And no, the 4790k can't handle 1080@60 unless it's running as a standalone encoding-only machine, or using the Superfast preset, which looks like junk.

01:20:23: Total frames encoded: 8426, total frames duplicated: 0 (0.00%) 01:20:23: Total frames rendered: 8448, number of late frames: 1 (0.01%) (it's okay for some frames to be late)

OBS is performing admirably. You could try using a slower preset, like Faster, instead of Very Fast, to improve the quality somewhat.

When you do your test runs though, make sure you're testing on high action gameplay, not static scenes. Five minutes or more to make sure its a representative sample.

I've found bicubic to look the best, imo.
