So I've been working on this project on and off for a couple of weeks now, and I've discovered lots of stuff. I've one more thing to solve - audio lag

Example 1 - recorded with FMLE in 720p 60 fps - FMLE does not allow me to reduce FPS to anything else, and therefore it saturates my upstream to the point where my 26 ping in QW becomes 150 ping 50 pl, and very unstable. However, as you can see in the recording, the audio lag is only about 0.5-1.0 seconds. Still there, though

Example 2 - recorded with xsplit in 720p 30 fps (xsplit is nicer about FPS (and resolutions)) - there are no side-effects on ping (I was playing on Australian server so I get 250-260 ping either way, and I've tested this on local servers too, ping is not affected) - However, the audio is really lagged as you can see, unacceptable for a general audience.

I am streaming by using a 2nd PC with an external capture card (blackmagic intensity shuttle) - I don't have an external audio mixer yet. Connections:

Game PC DVI1 -> Monitor
Game PC DVI2 -> Capture card HDMI
Game PC Audio -> Capture card Audio IN

Capture card USB -> Capture PC
Capture card Audio Out -> Headset

(I've tried HDMI audio and it doesn't work at all...)

If anyone can help, please do!

Thanks
Phil
