Dear guys and gals,


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
Restart

See attached for a edited registry key to inject. Tested on two surfaces with no ill effects.

edit: to answer a few questions: this increases performance on all touch aspects of the device

The most likely ill effect would be a decrease in battery life as the system must poll the touchscreen more often... just be aware. Otherwise, cool find.

Keyboard does seem faster... Does this also affect swiping? it seems like I can swipe in any way and get the full length of the page / app in one swipe?

Could this improve the home key button, when my surface is on standby it takes about 6 taps to get the surface to wake up.

I also have not noticed an increase in battery usage on my asus vivo tab. Not a surface, but rt.

What would decreasing the values to 1 due? I am assuming the lower the value, the better. Or did it not test well on Surface?

Originally I choose 2 to test the battery draw. However, now that I haven't seen any significant increase in battery usage the drop to 1 can be done.

Is it that easy for all the values? In other words, can all of the registry values be set to 1 to improve performance? Or are all the values a certain number for a reason? Cuz if latency of 1 works better than the original 8, idk why Microsoft would put it at 8 in the first place. Sorry for all the questions. This stuff is interesting to me!

First off all any values are "safe values". Some screens might be of worse quality then others (different manufacturers of parts). Having that value setup to happy medium means all screens act the same. You lower the value you demand that screen reads the inputs faster and more often. Might not be a good idea on some devices.

Not only talking about surface. Remember win8 (especially pro) will go on many different devices.

Also if you set sampling and refresh to low it might start having ghost touches from minimum input that would normally not be visible (oversensitive).

Best to practice and find perfect for you and your device.
