When it comes to some things, platform of choice doesn’t matter. Battery life is always a struggle, something will always lag, and Steve Ballmer will always be crazy. It doesn’t matter if you have iOS, Android, or Windows Phone, these pitfalls are sure to remain with us for time to come.
Recently, a method was released that’ll help increase touch responsiveness on the Microsoft Surface thanks to XDA Forum Member tamarasu. It’s not a particularly hard modification to make, as it is just a registry modification, and most users should be able to do it without any trouble. Here is how it’s done:
Found a key for touch prediction that when edited showed a marked improvement in keyboard responsiveness and small item manipulation ie classic desktop, file explorer, etc.
The key is: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TouchPredict ion
Edit key for latency from 8 to 2.
Edit sample time from 8 to 2
As stated, this is pretty easy to do. So far, everyone who has tried it has confirmed that it works very well. There are some caveats, though. XDA Recognized Developer GoodDayToDie noted that this will could affect battery life in a noticeable way for heavy users, as the system has to poll the screen much more frequently. Some haven’t noticed a decrease, but it’s likely that battery drain is increased as the touch screen is used more often. If you want better responsiveness on your Surface touch screen and don’t mind lessening your longevity, this is something worth trying.
