We've been doing retry with 1ms sleep if DecoderBeginFrame() returned E_PENDING which means application should call DecoderBeginFrame() again because GPU is busy. The 1ms sleep() during retry would result in usually about 15ms delay in reality because of bad clock precision on Windows. To improve throughput performance, this commit will enable high precision clock only for NVIDIA platform since DecoderBeginFrame() call on the other GPU vendors seems to succeed without retry.
