I just updated to this version, from the previous stable version. Win 8.1update1x64.
The actions log is spamming/scrolling out of control. Every second every running process is being listed with action "automatic gaming mode off", moreinfo "automatic gaming mode was...". I dont remember this happening with the previous version.
Fixed in v6.7.0.55 beta, now available.
This was a simple error on my part. I rushed out the change w/o testing, thinking 'testing is what betas are for'. I am so sorry, I will be sure to test betas better in the future prior to launch. Finals get a lot more testing, of course.
