Regarding the Change to Video Settings

After applying the new patch 3.1.2, when reaching the login screen you may receive the message, "Your video settings have changed." This is because the Projected Textures option in the Video Effects menu will now default to being turned on instead of turned off.

Q u o t e:
Super! I just hope this won't force-reset my current existing settings though. But as always I'll backup first just in case. ;)

It shouldn't change other settings (I just had a try and everything remained the same except this option).
