jays2kings 86079b029e Version 1.4.266
Flash Lightbar when at high latency now has the option to choose what
you decide is high latency
Show Notifications now has the option to only show warnings, such as
when a controller cannot be grabbed exclusively
Speaking of bad news for Windows 10 users: Hide DS4 has now been
disabled, until i can figure out why this is, it will be disabled, this
means some games that rely on this may not work properly or at all,
sorry about that
As for good news for Windows 10, did you know you can press Windows + G
to open a game bar which can record games. For Windows 10 users, there's
a new special action: Xbox Game DVR. Pick a trigger (only one button)
and tapping/holding/or double tapping does various things, such as
start/stop recording, save an ongoing recording, take a screenshot (via
the xbox app's option or your own hotkey ie form steam), or just open
the gamebar
Much of the code has been updated with c# 6.0
Added manifest so DS4Windows can notice Windows 10 and high DPIs, also
reorganized files
