Hi guys, Just purchased SB2 and had the same issue, found a solution on the Blender Forums - https://blenderartists.org/t/surface-book-pen-problems-using-grease-pencil/1123178/7
1.Open a Command Prompt window as an Administrator
2.Run "reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Pen /v LegacyPenInteractionModel /t REG_DWORD /d 1 /f"
The deadzone appears to be completely gone in both Blender and Zbrush, Photoshop is running fine too.
Wow thanks, this is really handy! Running Zbrush on my Surface Book 2 this eliminates the issue of needing to drag the cursor a certain distance to make a stroke.
However, now I'm noticing there's still a bit of lag between placing the pen down and when the stroke starts registering. For example, if I make a stroke too quickly it will not affect the mesh at all or only register the beginning of the stroke.
This issue isn't present on the trackpad or in other programs like Clip Studio Paint. Also, I have unchecked "Enable press and hold for right-clicking" in the pen and touch control panel settings. Performance setting is on "best performance". Anybody have any tips for this?
