I also game and was wanting to know if turning the brightness down would help with image retention?
The Brightness setting increases/decreases black level, it doesn't actually adjust screen brightness. The Contrast setting adjusts screen brightness but it's effect on IR seems to be hit or miss as some panels seem to be prone to persistent IR while others are very resistant to IR. I typically use Custom mode with Contrast set around 85% on my GT50 and i'm not having any IR problem despite watching lots of news and Speedchannel with bright logos. Others aren't so lucky.
There are several existing/redundant threads about "break in" you should be reading, here's one of the more recent ones:
