Question / Help Lagging frames when I never used to

I'd like to start streaming regularly, but I keep running into frames lagging resulting in stuttering motion in the video. What doesn't make sense to me is that my CPU never went above 55% and the game (League of Legends) gets a consistent 150+FPS. I've tried window capture and game capture, doesn't make a difference. I have also streamed a few times in the past 1080p@60 with perfectly smooth encoding. My hardware hasn't changed and now I get frames lagging with 720p@60. It's driving me insane because I know my computer can handle it, but I keep seeing my FPS drop from 60 to 55 or so every couple of seconds.

Anyway, here's my log:

Do you have frame drops without streaming?

1) Did you update your GPU drivers recently? Make sure your video card isn't under clocking while playing games.

Go to Nvidia control panel -> Manage 3D settings and under power management make sure it says "Prefer max performance." Keep an eye on your gpu temps using HWmonitor or something (although the 670 will run cooler than some older cards, like my 570).

2) You could have your CPU cores parked and you might need to unpark them.

That's the best I can think of right now =/

I checked Resource Monitor and half my cores are parked even when streaming. However, I'm pretty sure those are the hyper-threading cores, so I don't know if it matters. I tried the Nvidia control panel setting and it didn't make a difference. Just for the hell of it I set my stream to 640x360 (3x downscale) and 1000kbps and it still lags frames. I keep seeing it drop to anywhere from 50-59FPS. It rarely stays at 60 for more than a couple of seconds. This is such a pain in the ass.

EDIT: So, apparently Aero was causing the issue. I turned Aero on to get proper window capture working (couldn't get window capture to show the mouse cursor with it off) and as soon as I turned it off I got a rock solid 60FPS at 1080p or even 720 with the "fast" preset. I even tried 120FPS (my monitor's refresh rate) and that worked flawlessly. It's just annoying now that I can't really use window capture, unless someone knows how I can fix my Aero problems.

Window capture on windows 7 is not too efficient. It's unsurprising that you had that issue.
