So I'm having issues when streaming at 1920 x 1080p 60 FPS at the moment through Vmix.

When streaming, the Stream button flashes Orange and Red and I get the following message spammed in the stream status/log screen:
real-time buffer[vMix Video] too full (64% of 2560000000) ! frame dropped

System Specs:
BlackMagic 4K which receives the feed from the production machine.
i7-4770k
GTX 780
16GB RAM

Full Streaming Settings
Destination: Custom RTMP Server
URL: rtmp://live-lhr.twitch.tv/app

Input Size: 1920x1080
Frame Rate: 60
Quality: 1080p, 3.5Mbps
Application: FFMPEG

Edit:
CPU sits at around 30% total usage.
Memory sits at 13%

Make sure the latest vMix 15 is installed from our web site then from the quality settings in the streaming
window try increasing the thread count.

I had already tried increasing the thread count which does seem help and increases the threshold at which the frame rate drops to however it still seems to happen.
