The Surface RT firmware update Microsoft made available last week as part of this year's first Patch Tuesday brought with it a number of improvements, including improved audio playback in Connected Standby and “additional capabilities for handling firmware updates during low battery situations.” But as with most firmware updates, there are always issues, known and unknown, that remain unresolved until a future update — or, as in this case, a simple registry hack — gets rid of them.
An XDA Developer member, who goes by the handle "Tamarasu", last week posted a registry tweak that makes the ARM-powered Microsoft Surface RT's touchscreen more responsive . True, touch responsiveness may not figure prominently on every Surface owner's list of pet peeves, but it is a nifty little hack that many people will find helpful.
"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," Tamarasu wrote Thursday. "The key is: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TouchPredict ion."
Tamarasu suggests changing both "latency" and "sample time" from 8 to 2 and, finally, restarting the device in order for the changes to take effect.
However, please be warned that the increased responsiveness may have an adverse impact on the tablet's battery life. The good news is that most people who have tried the hack haven’t noticed a significant decrease in battery life.
