Monitor response time getting slower? RTC/Overdrive causing damage to monitor?

Bought a brand new Benq GL-2460 a month ago.
I would enable Advanced Motion Accelerator (Benq's version of RTC/overdrive) from time to time when playing games.

Everything was fine up until a week ago when I started noticing a little more motion blurriness while playing games and watching movies. It's like the response time has gotten slower or something...

Do you think the use of RTC/overdrive damaged the monitor in some way that caused a slower response time/ms?
