# OpenVR SDK 1.23.7HEADv1.23.7master

IVROverlay:
* Added the ability to specify the pitch angle (in radians) of the overlay before curvature is applied -- to form a fan or disk.  Previously, this used the global pitch angle, which prevented these overlays from being pitched independently (i.e. the cone segment or disk were always and only vertically aligned.  Note: The old behavior will continue to be applied when using the older interface to avoid breaking legacy apps.  Overlay applications which update to this version and were using pitched curved overlays, are now required to call SetOverlayPreCurvePitch explicitly.
* Added WaitFrameSync.  This function will block until the top of each frame, and can therefore be used to synchronize with the runtime's update rate.  Note: In non-async mode, some signals may be dropped due to scene app performance, so passing a timeout of 1000/refresh rate may be useful depending on the overlay app's desired behavior.

IVRRenderModels:
* Added VRRenderModelTextureFormat_RGBA16_FLOAT for loading dds textures.
* Added mipmap support to render model textures.

IVRDriverDirectModeComponent:
* PostPresent now takes throttling parameters.  Drivers which implement this interface can set Prop_SupportsAppThrottling_Bool to enable throttling / prediction UI in per-app video settings.

Driver Interface:
* Added VRInitError_Driver_WirelessHmdNotConnected. A driver can return this error when it expects to connect to an HMD over a wireless link, but has not yet connected. Instead of “HMD Not Found”, the user will be shown a message that encourages them to turn on their wireless headset.

App containers:
* Added VRInitError_Init_NoServerForAppContainer. This error can be returned when VR_Init is called from a process that is running inside an application container on Windows when SteamVR is not running. In this context, SteamVR must be running before the application can start.
