As per the title it seems the info cycle button does not work very well if at all with V-sync enabled. Sometimes after 20 or so presses it does go on to the next batch of info but it is very intermittent. Others have posted they have this problem too. Can you add this to the list of bugs please ISI. Thanks, Alric.
When you say V-Sync, are you talking about forced from the Nvidia control panel or from the game setup? I was able to replicate this in the game setup with Sync set to Software, but when set to GPU or Video it worked fine.
