`TooManyUniqueStateObjects`

There are too many unique instances of a particular type of state object.

`InvalidCall`

The method call is invalid. For example, a method’s parameter may not be a valid pointer.

`D3d101LibraryNotFound`

d3d10_1.dll cannot be loaded.

`FunctionNotFound`

Couldn’t find the function in the loaded DLL.

`InvalidUserPrivilege`

Current User is not Admin.

`ExpectedNonPrimaryDisplayHandle`

The handle corresponds to GDIPrimary.

`ExpectedComputeGpuHandle`

Setting Physx GPU requires that the GPU is compute-capable.

`StereoNotInitialized`

The Stereo part of NVAPI failed to initialize completely. Check if the stereo driver is installed.

`StereoRegistryAccessFailed`

Access to stereo-related registry keys or values has failed.

`StereoRegistryProfileTypeNotSupported`

The given registry profile type is not supported.

`StereoRegistryValueNotSupported`

The given registry value is not supported.
