osu!stable

No input from my tablet is detected

Don’t run osu! as admin.

I can’t reach certain areas of osu!’s window with my tablet

Set mouse sensitivity to 1.0x in osu!’s settings and disable “Map raw input to osu! window”.

My cursor is moving faster in osu! than in other applications

See above.

My cursor is only moving in an extremely small area on top left of osu!’s window

Do not use Windows Ink.

My cursor is shaky

That’s perfectly normal unless it’s going really crazy and teleports everywhere. In that case, see this section about resolving EMI issues.

If it is not an EMI issue and you still wanna remove the shakiness, try one of the many smoothing plugins that OpenTabletDriver and its community has to offer.

Valorant

Valorant is not detecting input from my tablet

Use the VMultiMode plugin’s VMulti Relative Mode as OpenTabletDriver’s output mode.

Make sure to read the following text before running Valorant.

Vanguard (Valorant’s anti-cheat software) blocks input from certain sources. This includes SendInput API which OpenTabletDriver uses in its Absolute Mode. VMulti is a kernel-level driver, which means that it is not affected by Vanguard. However, there are still some restrictions:

  • The first mouse input source that it detects is the only one that it allows to send input. This means that you MUST NOT use your mouse to open and play Valorant. Doing so leads to the tablet not working in Valorant.
  • Since VMulti exists as a separate input source than those that serves the mouse AND keyboard, this means that interacting with the keyboard will also cause issues in Valorant in certain cases.
    • You won’t be able to press “Left Click” while pressing any keyboard key. “Left Click” is a Vanguard-protected keybind.
    • Every time you press a keyboard key, the next two “Left Click”s will ALWAYS be dropped/blocked.
    • Pressing a keyboard key while holding “Left Click” will cause the “Left Click” to be dropped/blocked.

There is NO fix for this. All other drivers that rely on VMulti to send input are also affected without exception. This includes the original TabletDriver (Hawku, Devocub, etc.), XP-Pen, Huion, Gaomon, Veikk, etc.

As a workaround, do not use “Left Click” as your binding to “Fire” action. Instead, use an unused keyboard key then go to OpenTabletDriver and change your “Left Click” binding to that unused keyboard key.

Art Programs

Use Windows Ink plugin to enable pressure support. OpenTabletDriver does not support the WinTab API.

Clip Studio Paint

Photoshop CC

If Photoshop CC is not detecting pressure, try the following:

  1. Go to %appdata%\Adobe\Adobe Photoshop 2023\Adobe Photoshop 2023 Settings
  2. Check if there is a file called PSUserConfig.txt. If there is, open it. If not, create it.

# Use Windows Ink for tablet input

Replace 2023 with your version number if you’re using a different version of Photoshop CC.
