GROWLER GUNCAM [NOT A RELEASE]

i need some help. So please help a fellow mpgh member out as i tried to help you guys out in the past. I was wondering if anyone ever tried to record a vid on CA with growler guncam. the site said it wont affect gameplay performance but you know how advertiseres are, always lieing about their shit. So if anyone can hurriedly reply, tell me if it lags while recording. I want to make a montage dedicated to a good friend of mine ASAP. Thanks in advance( if i find that it wont lag, ill thank the poster with that info with the thanks button xD)
