Hey all,

I'm new to streaming so there is every chance this is a rookie error and I apologies in advance.

The fault:
When streaming (League of Legends) I get some FPS lag in game and the audio breaks up (small breaks like feedback/gaps in the audio). I believe my rig should be more than capable of handling streaming. Please see below details

System:
EVGA GeForce GTX780
Intel i7-920 @ 2.67GHz (8) ~ 2.8Ghz
Gigabyte EX58-UD5 (Using onboard audio)
6GB RAM
Wacom 23" DTU-2231 Tablet (1920x1080)
Samsung Rose 19" (1620x1080)
Headset if it matters is Razer Krakken 7.1 (USB)
Logitech C920 Webcam (HD)
Windows 7 Pro 64Bit

Internet:

Virgin 120MB. Getting roughly 98MB Down, 10MB Up.

Your settings seem fine, your system seems pretty decent, and there's no real report of errors in the log. Do you have a video of the problem?

Hey Jim,

Thanks for the response. Not at present but I'll record one when I get home tonight if that's OK?
Any preferred method for uploading the video (i.e. YouTube or upload file to here?)
