Question / Help Recording only issue with SLI or BenQ motionblur reduction??

So I have a really weird issue and I'm thinking it originates from either the fact that I run SLI or possibly from the blurbusters motion blur fixes which I am using, or just the fact that I have a 144hz monitor. These are shots in the dark though.

Here is a link to the utility I use from blurbusters http://www.blurbusters.com/benq/strobe-utility/ and I also am utilizing the nvidia setting which they suggest in the "Additional Improvement in Ghosting..." section if you scroll down a little bit on that page. I have a BenQ XL2411 144hz monitor for my main screen (although it's set to run @ 120hz because of that nvidia driver setting I just referenced).

The Issue: RECORDING at 720p 30fps causes frequent stuttering, not like a freeze sort of stutter (there's always motion) but more of a weird kind of extreme frame rubber banding in short bursts, not in-game but when I'm viewing the recording. This does not occur when I set OBS to 60fps, but I have experienced it at 30 and 45fps. The weird thing is I went to upload two comparison videos to YouTube to showcase the issue in action, and once they were uploaded the problem had magically disappeared. The source recordings still have the rubber banding on the 30fps settings, but not the YouTube versions. Same goes for when I stream and replay a short VoD to Twitch.

I've heard things about SLI incompatibilities but I also just noticed that watching the source recordings on my second monitor which is a standard LG 60hz monitor dramatically changes the nature of the stutters, there is still a kind of micro hang / lag every several seconds or so but it's very different and not nearly as pronounced as it is on my main BenQ monitor- and it's not really a rubberband effect on the 60hz monitor at all.

I've tried searching all over for a solution to this but I couldn't find anything. If it matters I'm running a new i5 4690k not yet overclocked, two GTX 660s in SLI which I've had for awhile and 16GB ram (I think the clock speeds are like 2000).

Thanks.

OBS Classic does indeed have major issues with SLI much of the time. Studio has multi-adapter compatibility which can reduce or eliminate most of these.

As far as the 'blur buster' software, I can only imagine that it acts as a DX hook, which indeed will interfere with OBS, just like MSI Afterburner, SweetFX and other visual mod/alteration software does.

Fully uninstall blurbuster, and disable SLI. Run a test recording. You kind of have two factors at the moment that absolutely could be causing significant issues, and need to rule them out before any other troubleshooting can take place.

Oh just an update while I still have this tab open in my browser (I'm a tab aholic), Studio is the bomb, using it and playing around with the SLI compatibility really helped me out. Also the color correction is bomb, silky smooth looking gameplay now w/ 720p 60fps online / offline and not even partnered.
