When running the DX11 test I get a "DirectX 11 measured result is too high to be possible and will be discarded." error message.

This error message will occur if the frame rate for the DX11 test is detected as being too high to be valid. This has been reported to occur in some instance when running video capture software (eg Nvidia shadowplay, AMD gaming evolved, fraps etc). If you see this error message please try disabling the video capture software before trying to run the test again.
