This tip makes some sense in making your Surface RT touch-screen display more responsive, while there are lot of fuss being made in the tablet industry at the moment, centering around the pros and cons of the most well-known tablets on the market and which piece of the hardware will reign supreme in the race to be king of the advanced slates. Contenders include the Apple iPad, the Microsoft Surface, the ASUS Nexus 7 and the Nexus 10 manufactured by Samsung. All of them are out with extremely capable options, but looks past their feature sets and in fact you’ll all find the same ultimate reason of issues that affect our user experience. Already opted for the Microsoft Surface RT tablet, then this discovery of one individual could go some way to eradicate the touch-screen responsiveness issues, if you are been facing.
However, some Surface RT tablet owners may not even have an issue with how responsive the touch-screen is on the device, but for some people it may be irritating how the screen responds to your touch and could be finding themselves increasingly frustrated as they continue to use it. In fact the users question has invested the time in exploring the underlying file system and registery and has been able to find a key factor that corresponds to the touch-screen. Improving the feel and responsiveness of the display involves interrogating the key and making some small changes to two of the whole contained within it.
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.
Here’s – The registry key in question is specified as:
with tow values needing to be edited (changed) internally to transform the default latency and sample times when interating with the touch display. The finder of the key notes that he has personally changed the latency down from the default 8 to 2 and the sample times also from 8 to 2.
Edit key for latency from 8 to 2.
Edit sample time from 8 to 2
Restart of the device will need to be carried out for the changes to take effect.
However this process has been tested on a number of Surface tablets with no ill effect, and worth noting that a number of people fear it could have a nagative effect on the batter life due to the system having to poll the touch-screen on a more regular basic, It has been noted that this could affect battery life in a noticeable way for heavy users, as the system has to poll the screen much more frequently. In fact, the results appear to be in a notable improvement in keyboard responsiveness as well as a marked improvement with scrolling, allowing us to whizz through more information with each scroll gesture.
Still it is considerably worth trading-off when we cinteract with the display constantly when using our RT tablets and don’t mind about the battery drainage, this is something worth trying. (via XDA-Developers)
