Name Value Description
AllOkay 0 Signifies that everything is ideal: context created successfully, all required and optional features are available,
and browser did not signal a major performance caveat.
MissingOptionalFeatures 1 Signifies that the base requirements of compatibility are met but at least some optional features are missing.
Consult the contents of WebGLRenderCompatibilityInfo.missingOptionalFeatures.
MajorPerformanceCaveat 2 Signifies that the base requirements of compatibility are met but WebGL reported a major performance caveat. The browser
has likely fallen back to software rendering due to lack of a usable GPU.
Consult WebGLRenderCompatibilityInfo.contextErrorMessage for a possible description of what went wrong.
There could also be some missing optional features; consult the contents of WebGLRenderCompatibilityInfo.missingOptionalFeatures.
MissingRequiredFeatures 3 Signifies that the base requirements of compatibility are not met; rendering cannot occur.
Consult the contents of WebGLRenderCompatibilityInfo.missingRequiredFeatures.
CannotCreateContext 4 Signifies an inability to create either a canvas or a WebGL rendering context; rendering cannot occur. Consult
WebGLRenderCompatibilityInfo.contextErrorMessage for a possible description of what went wrong.
