Question / Help Getting stuttering in game while streaming. Monitor refresh rate drop?

As the title suggests, I am having a weird issue with my refresh rate being dropped down when OBS is in use. I noticed it in games and then tried a few other tests and noticed it as well. My monitor is at 100hz normally. After noticing the refresh rate drop I went to testufo.com to check the refresh rate. It is normal while OBS is idle, but as soon as I start streaming, recording, or even previewing the stream, it causes the refresh rate to stutter badly and jumps between 60 and 75hz. It would not normally be an issue, but it is not constant and the refresh rate is constantly jumping around, causing weird stuttering. OBS shows a solid 30fps while streaming with no dropped frames and the game shows solid fps (depending on the game). Even with constant framerates according to the programs, the stuttering is still there while OBS is on.

Vsync has to be on in-game for my recordings or stream to even be watchable, without vsync the stream is extremely choppy.

My specs:

Windows 10
i7-4770k
GTX 980ti
16GB RAM
Game and OBS on SSD.
1440p Main Monitor, 2 x 1080p secondary monitors
150mb down / 25mb up connection

I have tried adjusting all settings in OBS and still nothing. Current bitrate is at 3500, video stream quality is 1440p down sampled to 720p at 30fps. I tried downsampling all the way down to the lowest video settings, different capture modes, and it still does it no matter what.

Any help with this is greatly appreciated.

Thanks!

yeah i downloaded overwatch and have the same issue, less severe but same no matter what encoder qs, nvenc or x264, game looks almost cheap like TF2 and gives problems while BF4 records for me perfectly and smooth

It can't be the game. There are a few hundred streamers with worse hardware streaming 60fps overwatch.

I also recorded a video of Dota 2 in case it was Overwatch, but it has the same issue.

Edit:

I tried using Shadowplay to stream/record and it works perfectly:

So it isn't a hardware issue, but I would really like to get OBS working so I can have more customization. Shadowplay is pretty lacking in that department.

One more edit:

I then tried 1080p 60fps for fun with shadowplay and it also works fine:

Something with OBS is amiss. Hopefully it can be figured out =)
