I have been trying to stream league of legends. in 720p. I'm using the game capture option. I'm getting sort of low fps when i normally have high fps anywhere from 140-190 and now i get about 45-60. Also getting choppy fps like i'm missing frames from the game. I have tried different settings, all the same it seems. I have a Q9650, 8 gig of ram, 650 gig hd, Nvidia gtx 285 and 4.5mb up and 20mb down internet.

I notice you're using window capture, that's good, but could you try turning aero on and see if it makes a difference? (You also have to use the windows aero theme as well if you're not already)

I think this might be your problem but I'm just guessing since I just installed Open Broadcaster this morning on my PC. http://youtu.be/0xCl1BD88fw?t=14m53s watch about three or four minutes of this video from this point, the x264 CPU present might be set to very fast which will makes things choppy. Try lowering it to a better setting like normal. The slower you go the more strain you put on your CPU but the video will display smoother this will really help when you are moving in game play. Hope this helps and have fun.

jscobee - that's incorrect, it goes in the opposite direction, the name of the preset implies how fast the encoder itself should run. so "veryfast" means the encoder is set to run very fast and not use much CPU, "ultrafast" means it uses as little CPU as possible. you should avoid ever using any preset slower than "veryfast" if possible because it will cause much more CPU strain.

bryandaman22 - try game capture instead, then.

I'm streaming LoL among other games and I noticed a huuuge difference pulling down the fps on the video tab from 59 to something like 40.

I've been having odd problems streaming 1080p with a pretty good machine and CPU but the FPS made all the difference for me. I could easily raise my bitrate up to 4k when pulling the FPS down a bit.
