Game Compatibility

Graphics API	Non-VR	OpenXR	Oculus	OpenVR (SteamVR)
OpenGL	❌	❌	❌	✅
Direct3D 11	✅	✅	✅	✅
Direct3D 12	❌	✅	✅	✅
Vulkan	❌	✅	❌	✅

Oculus API: only Link or Air Link are supported; Virtual Desktop or other similar tools are only supported via SteamVR or OpenXR. Where possible, OpenXR is strongly recommended instead.

OpenXR + Vulkan: the game must use XR_KHR_vulkan_enable2 and the xrCreateVulkanInstanceKHR() + xrCreateVulkanDeviceKHR() functions.

Common Games

BeamNG.drive	untested	❌	n/a	✅

BeamNG.drive: as of April 4th, 2024, BeamNG.drive in VR is incompatible except when using SteamVR, because BeamNG.drive does not use XR_KHR_vulkan_enable2 + xrCreateVulkanInstanceKHR() + xrCreateVulkanDeviceKHR().

Advice

• For VR: use OpenXR if possible - otherwise use OpenVR (SteamVR). OpenXR will give you the best performance and reliability
• OpenVR is the least likely mode to have compatibility issues, followed shortly by OpenXR. Non-VR and Oculus have significantly higher chances of issues
• Setting WinTab to ‘invasive’ in input settings also raises the chance of issues

Anti-Cheat

While OpenKneeboard is not a cheat, it does hook into the games rendering and input pipelines, which over-eager anti-cheat systems may consider ban-worthy. While this is similar to how other overlays work (e.g. Steam and Discord), it is possible that using OpenKneeboard may lead to an anti-cheat ban.

As of March 19th, 2024, the developers have not received any reports of any users receiving any bans in any games, but this remains a theoretical possibility in the future.

Note that OpenKneeboard has NO WARRANTY; see the LICENSE file and full text of the GPLv2 for details.

OpenComposite

OpenKneeboard is not tested with OpenComposite, and issues will not be investigated.
