Microsoft Surface Pro 6 and earlier are trying to combine the best of tablets and full Windows 10 PCs. Although the idea generally works, the consensus is that Surface is not as good at being a tablet as an Apple iPad. Part of this is due to hardware, another part is software.
One area that can be improved is tactile responsiveness. This function is supposed to be achieved by simply changing the registry on the Surface Pro (any generation) or any Windows 10 PC with touch support, like the new Samsung Galaxy Book2.
In the Windows 10 registry, there are parameters to change latency and sampling time, both will be increase the responsiveness of the touch screen when it is decreased. As mentioned above, the potential disadvantage is the decrease in battery life. However, many users who make this change claim that any change in battery life is imperceptible to detection, or at least invisible.
Litigation article: Brandon Paddock from Microsoft notes that this tip does not quite what some people think:
"This value DOES NOT change the polling frequency or the sample rate of the touch screen, it only lies to the prediction engine as to the nature of these values, which affects its ability to function properly. a predictor of what those values are, breaking down their ability to do their job well, at best you give invalid values that they ignore. "
As always, we will leave it up to the user to determine if the experience is worse or better for himself. Just be aware that Microsoft obviously does not support or approve this change or our article.
If you notice massive battery downgrades or other abnormalities, you can quickly cancel the registry change and return to normal.
It is important to note that if you are using Windows 10 in S mode, as with the delivery of Surface Go or Galaxy Book 2, you can not access the registry in this configuration and you will need to exit S mode for it to work .
Finally, the difficulty and the risk factor for this "hack" are also "easy" and "weak".
How to change tactile sensitivity under Windows 10
Since Microsoft does not offer a way to change touch sensitivity through the Windows 10 operating system, the most direct way to do this is to use the registry.
Warning: Changing the system registry can have serious consequences if it is not followed to the letter: driver failures, system instability, unable to boot Windows. Users are always prompted to perform a system backup before making any changes to the registry.
To increase or decrease the touch responsiveness on your PC, follow these steps:
- type registry editor in the search box.
-
Click on Yes in the User Account Control window.
-
Move towards
HKEY_LOCAL_MACHINE SOFTWARE Microsoft TouchPrediction
- Double-click on Latency and change the default 8 at 2 (or less) in the Value data box.
-
Hit D & # 39; agreement once you have finished.
-
Double-click on Time of sampling and change the default 8 at 2 (or less) in the Value data box. Hit OK when done.
- Close the registry editor.
- Restart the computer to make sure the changes take effect.
The exact value for setting Latency and SampleTime is questionable. Most users set it to "2", but others set it to "1" or even "0", which probably makes it even more responsive. Due to the likely impact on battery life, setting to "2" seems to be the best choice, as it provides a substantial improvement without any noticeable side effects.
Does it really improve responsiveness to touch?
If you frequently use the touch screen on your PC, then yes, it will give the PC a much more natural, fluid and responsive feel. As to what value you get out of it – and if it materially affects battery life – can be debated, but there does not seem to be any dramatic negative consequences, and that's why we suggest it.
The most interesting question is why Microsoft does not set a lower default value. The immediate explanation would seem to be to maximize the life of the battery. One solution for Microsoft could be simply to place this in Windows settings and allow users to access a slider with a small warning indicating that increased sensitivity could affect the lifetime of the drums.
Like all things Microsoft today, the best way to send your requests to Microsoft is the Feedback Hub integrated with Windows 10.
