lag on windows 8

[XieRH]

Just would like to know, have windows 8 users been experiencing severe lag on their desktop when trying to broadcast? I noticed that during my broadcast the framerate always dips to sub-20FPS levels (usually around 18-19) regardless of what quality I choose to broadcast in. The lag is very noticeable from things like dragging windows around to the cursor movement, but there are no issues on the broadcast side (framerates are still smooth for viewers watching the stream). I don't have any concrete info on whether procaster is yet to be optimised for Windows 8 so I'd like to enquire.


For reference, these are the specs for my PC and speedtest
OS: Windows 8 Pro
CPU: i7 3630QM
GPU: nVidia GTX675m
RAM: 8GB
Speedtest: 54.07Mbps download, 25.29Mbps upload
