Question / Help Low fps ingame even though PC specs are okay

[MushRoomD]

So, I want to stream league of legends. My internet is fine, I have a good upload speed so that ain't a problem. Thing is, I use 1920x1080 ingame resolution and downscale to 720p on stream. I lowered all the graphics settings in game to low and without stream I get around 120 fps even with medium settings. When I start up the stream, fps ingame drops to 20-25, sometimes goes up to 30 and therefore stream is really laggy fps-wise.
My PC specs are
CPU: AMD Phenom II x4 945
RAM: 4 gigs of 1300 mhz RAM
GPU: ATI 6870

Tips?

Use Window Capture+Enable Aero or Game Capture. Monitor Capture is the worst method unless you're running Windows 8. Use the scene switcher plugin at http://obsproject.com/forum/viewtopic.php?f=11&t=1785 to automatically bounce between the game and the lobby.
