HTC has pushed out an update for their Windows Phone Sound Enhancer. While no change log is available to let us know what all the update accomplishes, it appears to improve the graphics lag.
The graphics lag appears when the SRS Enhancements are turned on in the Sound Enhancer and can be a little on the annoying side. The graphics lag wasn't present in every app, mainly the games that had greater graphics animations (e.g. Fruit Ninja, Line Birds, etc.). We've never received official confirmation that the two are related but after applying the recent update, the lag doesn't appear to be present.
The Sound Enhancer has been updated several times and with each update, the graphics lag issue seems to get a little better. Maybe this update did the trick.
For those who have installed the update, see any changes?
Thanks, Yodani, for the tip!
