Question / Help Framerate drops while streaming WoW.

Hello. I'm noticing a huge FPS drop in WoW. I usually run around 85-100 FPS but whenever I begin to stream it drops around 20-35 FPS. Now I know my computer is strong enough to run it. I can't find what the problem is.

Motherboard - Intel DX58SO
CPU - Intel Core i7 920 @ 2.67 ghz
Memory - Corsair 6GB
Graphics - Radeon HD5750

Post a log file from a live streaming session; they're located in %appdata%\OBS\logs and are timestamped appropriately. Just open one with Notepad and post the results here between 'code' tags to keep things neat.
Run a 6MB test at http://testmy.net/upload (speedtest.net is useless for livestreaming purposes, testmy checks constant throughput, which is what's important for livestreaming).

I'd guess either the video card (as it's an older, mid-to-low end card), RAM (as both OBS and WoW are kind of memory-hungry), or that you might be using Monitor Capture mode, which is the slowest/worst of all capture options and should be avoided at all costs.

We'll need the log file and testmy results to be able to tell more.

Ok here is the log. My upload speed is at 4.9 mbps from the site you referred me to. And I was running in monitor capture mode. What would be the best situation for me since I'm only running one monitor?

Yeah, the monitor capture is almost definitely causing those frames to lag on the stream, and can cause in-game slowdowns.
Turn Aero ON. It's counter-intuitive, but OBS can hook the window textures from Aero if it's enabled, under Win7.
Use Game Capture, or if you only get a blackscreen, then use Window Capture. One of the two will work.

Lagged frames = local system problem (And at about 70% of frames lagged, this is the issue, with using monitor capture being far and away THE most likely cause. Swapping to Game/Window cap almost definitely will fix this.)
Dropped frames = network problem (Not your problem, with 0% dropped)

Also, unless I'm missing something, you aren't recording locally... should turn CFR *off*. It's only really there for if you're recording video to be edited later with something like Sony Vegas, which can really pitch a fit with a non-constant rate.
Also, ditch DXtory. It's only needed for XSplit because their capture solution is... lacking (sucks). Native OBS game/window cap will give you higher performance.
