Gaming Evolved/Raptr Session Video feature

[Gnash]

During heavy in-game lag, like this afternoon from about 12 pm (-8:00 GMT) til 1:30ish, I experienced the worst lag to date in RoR and CTD after the lord room was (literally at the time) assholes to elbows in Order; we had only 100% AAO, but that's 100% of 3, almost 4, WBs. So there were many, many players, which makes for epic times, until there's a mass CTD/DC, which I know happens server wide regardless of faction.
My question: has anyone encountered these circumstances while running a video capture app, specifically AMD's Gaming Evolved/Raptr app, and in general, i.e., FRAPS, etc.?
If so, did turning the capture quality down help? Or was turning it off the solution?
I love being able to capture battles, but ultimately will lose said feature if its compromising my connection/GPU/Processor. Any advice is appreciated

Good hunting.
