Small Registry Hack Improves Touchscreen Lag for the Surface RT

Small Registry Hack Improves Touchscreen Lag for the Surface RT

With the Windows RT jailbreak method now easily available, its only a matter of time before we start to see some pretty cooler homebrew fixes and apps that take advantage of the unlocked potential of the ARM version of Windows. While this latest hack doesn’t have anything directly to do with the jailbreak effort, it does prove that an active modding community is starting to exist for Windows RT.

This latest mod is all about addressing some lag issues with the touch experience in Surface RT.

All that is involved is a simple registry hack, yup that’s it. To make the change, type “regedit” in the Start Screen. From there, find the following:


What you want to do is change the “latency” over from 8 to 2, and sample time needs changed to 2 as well. Just like that, Surface users report that things are much smoother now, though it is also reported that a very small hit to battery life might occur as well.

Why the battery drain? Simply put, the device will be polling the screen much more. Still, the hit is probably not even that noticeable for most users. No report on what kind of difference, but I’d expect the difference to be rather tiny (10-20 minutes maybe?).

For all the details on this little hack, head over to the XDA developer’s forum. Has anyone tried this yet, if so, is there a noticeable difference in display responsiveness in your opinion or not?
