Read update I found a fix!
This isn't exclusively an OBS issue but since theres a great deal of capable people around here, let's give this a go.
Basically, League of Legends produces a delayed frames every 0.5-2 seconds in the most trivial situations, for example when OBS is rendering a 360p 24fps preview/stream (or higher), or when my camera preview window is "in sight". (it's ok when hidden behind a different window). (also preview is disabled in obs)
Using Aero Theme and Vertical Sync in LoL.
It's mostly an issue in borderless window, but fullscreen mode has an even harder to notice subtle stutter no matter what in LoL.
The sad part is, it's soo smoooth when avoiding these situations (cam preview not in sight/obs not rendering)
UPDATE: While I was writing this I found a fix. Minimize OBS while it's rendering. Just turning off preview wasn't enough.
If you use a monitor with strobed backlight and vsync you can notice the issue easily, probably. Hardware I'm using is 1090T and HD 7770, Win7
Not sure if this should go in bug reports or guides instead now, maybe someone move it where it's helpful!
edit: this is mostly a problem for multi screen users I'd imagine, unless someone has problematic apps displayed while playing in windowed. oh and SKYPE in sight also causes the problem.
