Pen-Cursor: Disable

Is this the right place for this question??

Good evening everyone.

I just got a Surface Pro 3.

It uses N-Trig technology for its pen.

This has the disadvantage of having a worse hover delay.

So I did increase its sample rate within the registry.

(HKLM\Software\Microsoft\TouchPrediction: Latency, SampleTime)

However, that did not help to much.

Alternatively, is there a way to disable the pen cursor within the registry?

(That might solve the problem as the precision while actually inking is fair enough.)

Thanks alot for your help!!
